The need for students, home users and business professionals to work remotely is growing therefore laptops are becoming increasingly common to fill this need. Laptops are useful computing and entertainment machines because they are powerful and portable. Many homes and offices are equipped with wireless and networking capabilities enabling a laptop computer to be used in the facility for gaming, entertainment, work, and watching television. The growing computer and technology industry has been able to make smaller and more powerful laptops therefore the difference in performance between desktop computers and laptops is steadily becoming narrower. The need for people in society to work remotely, on location and to use their computing device in different places creates a need for the mobility that laptop computers provide. They are a good tech solution for people who travel and need to bring their computers with them to perform work.
Laptops are smaller in size and much lighter than desktop systems. Their frames and internal components are much smaller than their desktop counterparts. Many of them are equipped with LCD screens that come in a range of sizes to provide consumers with options. Some consumers may prefer a laptop with a 14 inch screen and others may prefer a full sized 17 inch screen for a wider display area. Thickness is another factor that differentiates laptop computers and desktop systems. Today laptops can come in very thin sizes. Apple MacBook laptops tend to be some of the thinnest that are available in the market. Many people value laptops because of their compact size, their significantly lighter weight, and their portability as compared to desktop computers. Laptop computers tend to range between five and seven pounds although some models can weight much less.

Users may need to sacrifice durability but the hardware and capabilities of laptop computers is advancing and becoming more powerful. There was a time in history when the performance of a desktop computer was unparalleled but that gap has significantly narrowed over the years. Laptop computers come with hard drives and storage capacities that can be in the terabytes and powerful processors including quad cores. There are also high end gaming laptops available in the market such as the Alienware M14x R2 AM14XR2-6111BK 14.0-Inch system or the MSI Computer Corp GT70 17.3 inch system. In the computer industry laptops have become more than simple word processing and computing devices. Laptops have become powerful multimedia, entertainment, and gaming systems.

The biggest benefits for students, home users and business professionals that use laptop computers are mobility and networking. It is becoming increasingly important for people to have their personal computer or computing device with them in locations other than the classroom, home or office. Desktop computers are too heavy and large to carry around to different locations and generally anchor their users to a single work location. There have been advancements in cloud computing, networking and remote data access but a computing device is still required to perform the work.

Laptops fill the growing need for students, home users and business professionals to work and use their computers remotely. Desktop computers are not portable and mobile whereas laptops can be easily carried to different locations. Laptop computers will continue to become equipped with better hardware and capabilities as technology advances to close any existing gap in performance with desktop computers.

Writing about technology and computers is a passion of mine because gadgets and devices assist people in their daily lives. I write to share my knowledge in technology with others because I believe we all grow together. I particularly enjoy writing reviews for technology products including computers and laptops because they are a common tech gadget in homes and businesses that people use daily to work and connect with others.

Network Interfaces and Ports - Is There Any Difference?

 By Barry Burdette 

Photo: i.dell.com
 
Over the long course of my career I have heard many of my colleagues refer to these two terms interchangeably, although this is actually not true and may cost you a wrong answer on an exam such as Cisco's CCNA or CCNP which could make the difference between you passing the exam or not. Let us take a look at the differences in these two terms.

Ports:
The Port resides at layer 1 of the OSI model, the Physical layer. This layer defines the electrical and physical specifications for a device, such as copper or fiber media as well as the voltages, line impedance, signal timing, and the physical layout of pins for the connecting device such as twisted pairs, coaxial or in the case of fiber cable single mode or multi-mode.

Interfaces:
The Interface resides at layer 2 of the OSI model, the Data Link layer. This layer defines the functional and procedural method of transferring data between network devices, such as Serial, Ethernet, FDDI, and Token-Ring. Additionally this layer may provide the ability to detect and maybe correct errors that might occur at the physical layer.

Virtual Interfaces:
There are a number of interfaces that have no physical connection to any device such as Loopbacks, Lines, and VLANs. These interfaces are referred to as virtual interfaces, and although these interfaces have no physical connection they can still be addressed and accessed by other devices in a network. Interfaces such as Loopback interfaces are very useful in insuring devices are reachable with many routing protocols.

Sub interfaces are another form of virtual interface and are used in WAN connections like Frame-Relay, and VLAN Trunks between routers and switches when creating a router on a stick to route between VLANs or deploying DHCP addressing for multiple VLANs.

In conclusion the line between Ports and Interfaces may be blurry, and in the real world the two terms may be used interchangeably but there is a difference and you need to understand the difference not only to pass an exam, but to help you properly configure network interfaces on Cisco routing and switch equipment and help you troubleshoot some complex networking issues. A good way to remember this is you use some form of media to physically connect a network port to another network device port and you configure a network interface with some form of protocol to allow communication between network devices on a LAN or WAN.

Types of Computer Hardware

Author: Isabel

Photo: http://images03.olx.in
 
Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.

Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware's found in a computer.

Ø Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.

Ø Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.

Ø Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.

Ø Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.

Ø Power Supply: Power Supply supplies electrical energy to an output load or group of loads.

Ø Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.

Ø Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.

Ø CD-ROM drive: It contains data accessible by a computer

Ø Floppy disk: It is a data storage device

Ø Zip Drive: It is a medium capacity removable disk storage system.

Ø Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.

Try Simple Fixes Before Getting Computer Tech Support

 By Darin McGilvra 

Photo: cdn.canadianfinanceblog.com
 
Have you recently gotten the dreaded "Blue Screen of Death?" You may not need to get computer tech support. Try some simple fixes first before looking for professional help. Even if they don't fix the problem, you can gain some valuable information that will help speed up the process of fixing your computer when you do get computer tech support.

When you do get the blue screen, write down the error message that tells you what the problem is. These messages can be cryptic and confusing, but it may prove helpful for diagnosing the problem. Just as important, you will want to make sure the next time you get the blue screen that it is because of the same problem.

With most problems with a computer, you should try restarting it. The problem may have happened on start-up. Restarting the computer could fix the error. If the blue screen does reappear, make sure it is the same error message you had received before.

Once the computer has gone through the start-up process, see if you can reproduce the blue screen. Try to remember exactly what you were doing when the blue screen popped up. Go into the same software you were working on. If you get the blue screen every time you work in a certain software, especially one that you recently installed or updated, it's a good bet the problem is in the software.
If it is a software problem, try running the software on a different computer. If you still get the blue screen, then the problem is in the software. If not, then the problem is compatibility between the software and the original computer.

Try uninstalling the software to get rid of the blue screen problem. Most software comes with an uninstall program, or you can go into the uninstall program on a Windows computer in the Control Panel.

If you are unable to uninstall the software, you may try using a System Restore on a computer with Windows XP or newer. This also can be done through the Control Panel. This will erase anything done to the computer after the date of the System Restore.

If it does not appear to be a software problem, you may try investigating the error message you keep receiving. Paste the message into a search engine and see what results pop up. If other people have received this error message, they may have figured out the problem and posted this problem, and possibly a solution, online.

If you're still stuck, you might check to see if you have a virus or some other type of malware. Run an antivirus program on your computer and fix any problems that are found, if possible.
The problem could even be a hardware issue. Check air vents to see if fans are running properly and that vents are clear of dust and debris. If you feel confident about it, you could even shut down the computer, open up the case, and turn on the computer to see if all the fans are running.

If your problem persists, it would be a good idea to contact a trusted computer tech support company. Fortunately, you'll be armed with information to help the tech diagnose your problem.

Compact Flash Card Recovery and USB Flash Drive Recovery

Author: Hardley Thompson

Photo: s3.static.mymemory.co.uk

Compact flash cards and USB flash drive are small storage devices, easy to carry, used to gain additional storage capacity, to backup files or to transfer information from one device to another. These storage devices are reusable, can be erased and reused indefinitely without loss of existent data.

Data loss on compact flash cards or USB can occur through accidental deletion or formatting, from physical damage or virus attack, and the list can go on. The ideal case is when data was deleted or accidental formatted, because the files aren't completely erased. They are still there and can be recovered. USB flash drive recovery or compact flash card recovery can be done in companies specialized in data recovery.
As time passes we tend to depend more and more on technology and the reason for that is that these devices make our life simpler and easier. While there are many reasons for data loss, the evolving technology makes recovering accidentally deleted data from USB flash drives easier.

If your storage device has been under a virus attack, it is indicated that the files should be quarantined and the rest of the data transferred on your computer's hard disk.

Also, make sure that you or other people don't try recovering data if you aren't sure what are you doing or use the broken USB, because this could lead to permanent and irremediable losses. If we face with data loss we should seek a company that is specialized in USB flash drive recovery, compact flash card recovery or other similar devices. These professionals will help you easily recover data from damaged units. They use specific software programs that have been specifically designed for such such recovery operations and aren't usually available for sale for the general public.

If you get your hands on a USB flash drive recovery or compact flash card recovery software and want to try the recovery yourself, you must follow these steps:

For the recovery of deleted files there must be a "Deleted Recovery" option.
In case of accidental formatting you should use the "Format Recovery" option. From the partitions list, the software will choose your flash drive.

Clicking the "Scan" option will open a new window.  Remove the files needed form the folders available, then select the ones you need recovery for.

Click "Recover" in order to start the data recovery process. Recovered data can be stored on hard disk or any storage device other than the one in question.

Once the operation is finished click the "OK" button to complete  the  USB flash drive recovery or compact flash card recovery process.

Closing the page, in order to keep important data safe, it is not necessary to store them on a second storage device, it is advisable to have multiple copies stored on more than 2 devices to increase the chances of recovery data. Also if you are not sure what to do in this situation seek advise from professionals.

Common Laptop Faults To Look Out For

 By Noah Zee 

Photo: cdn3.sbnation.com
 
A laptop computer shouldn't be viewed as unbreakable, you will find there are plenty of issues that might go drastically wrong in day-to-day use, from bumps and scrapes or computer software complications to hardware problems. Having a laptop computer which is frequently carried with you means that anything at all might happen and it may be rather frustrating if issues are encountered. Being familiar with possible laptop errors can help you to self-diagnose complications and from that point figure out the appropriate plan of action to get the issue solved. Here are several of the most common complications where a laptop computer may have to be mended -

Bumps & Knocks

Laptops are designed with mobility at heart, and because of the continual traveling to and fro, they can withstand a substantial amount of punishment. A substantial bump can certainly trigger a laptop computer to fail. Impact damage can damage the external shell or case and even more importantly result in the harddrive malfunctioning. For the case, a couple of good bumps could before long leave the outer shell damaged, warped or dinged up. And, with regards to the inner elements, an unexpected jolt could result in damage to the harddrive or mother board, which can result in the laptop becoming unusable.

Overheating

Quite a frequent issue with laptop computers is getting too hot which generally develops from a fan no longer working efficiently enough. In the event the fan is obstructed, which often can occur when the laptop is put on a soft or textile surface area or blocked with airborne debris, than this might quickly result in the laptop starting to overheat. When the fan isn't capable of working as designed, the interior elements, for example the Central processing unit and hard drive may very well get too hot, which can force the laptop computer to immediately power down - this is usually a built-in, protective measure to prevent long-term harm.

Life Of The Battery

In the event the battery pack isn't in a position to charge then chances are it will be an issue with the exterior power supply or perhaps a defective power jack. The power jack, it is the outlet on the side or rear of the laptop computer which allows you to connect to the AC adapter and it is fairly susceptible to damage because of the frequency of its use. When the AC adapter is often connected and removed, the jack may well come unfastened from the mounting within the mother board, which could result in charging related difficulties.

How to choose between: Netbook vs Laptop

 by: Dawood Mamedoff

Photo: techmaza.in
 
 Share of netbooks at PC market has rapidly grown recently. They are more often considered as a future replacement for regular laptops that used to utilize before. However there is an inherent confusion as to what exactly a netbook is and how it compares to a laptop. Undoubtedly both of them have their own advantages and shortages. In order to make your life easier when choosing between 2 gadgets we have listed below points to consider before purchasing:

Size. What you surely feel in the first instance about netbooks is their size. Netbook’s display usually ranges from 7 to 10 inches whereas laptops normally start from 14 inches. This consequently makes netbooks much smaller and lighter comparing to laptops. They are so portable that you may carry them in a purse or small backpack.

Resolution. Most of netbooks currently allow for maximum screen resolution at 1024x600. Anything below doesn’t let you to view whole width of the web page at any one time. So the user has to scroll the page back and forth to read a full line of text. However most recent netbooks are usually produced to allow 1024x600 which is ok for comfortable surfing over majority of web-sites.

Power. The smaller size of netbooks makes them much more power efficient. So you can use a netbook for 5-6 hours without recharging batteries which is about 3 times longer than your average laptop. This feature together with an increased portability puts netbooks in a category of must-have stuff for long distant travellers.

Performance. Of course a size is not the only difference between these 2 categories of gadgets. The main shortage of netbooks relates to their weaker performance specifications. Lower hard drive speed, processor speed and graphics memory apparently do not add any value to the attractiveness of netbooks. Therefore running any sort of processor-intensive jobs like graphics, footage or video modifying wouldn’t be as smooth as it used to be on laptops. Even excessive playing of videos on sites like Youtube can also slow down your netbook considerably. 

Keyboard. Another major complaint about netbooks is the dimension of the keyboards. If you have large fingers, you’ll find that you spend as much time correcting typos as you do typing. Netbooks generally carry scrunched up small keyboards that are rather uncomfortable to type on, making them unsuitable for note taking.

Optical drives and connectivity. Netbooks usually do not have an optical disc drives - so that means no CDs or DVDs. Nonetheless, connectivity is a central focus for netbooks. All of them come with Wi-Fi built in and an increasing number now also have Bluetooth on board, so they can be connected wirelessly to a 3G mobile phone for internet access on the move.

Price. And the last but apparently not least point to consider is the price. Netbooks cost between $200-$500 depending on how fancy you want it and what you are using it for. The cheapest laptops start at around $400. With a low end netbook, you can get on the Internet, type and edit documents, and play some games that don’t need a lot of graphics to run smoothly. The higher end models offer more storage, more RAM, and more features.

 By Danny Bob 

Photo: 3.bp.blogspot.com

Quite often you come across a situation where you need to recover deleted files that you may have removed through (Shift + Del) or by clearing your recycle bin, in such an event you can use some of the popular data recovery software's that you can easily find on the internet.
Ideally when you need to recover deleted files, what happens is that only the reference location of the directory structure is deleted while the space that has stored the original data remains unused. Unless you have overwritten in that space, files can be recovered easily and these software's are easy to use and resourceful. Also, for this software's to be effective, it is also important that the user do not carry out any sort of formatting or disk defragmentation to the hard disk after deleting the file.
Here are some useful software's that you could use to help recover your deleted files.
Kickass Undelete
This software is a portable recovery system and an open source application that can be used on Windows platforms. To make it work, just open the software and on the left panel you will see the directories. Click on directory that originally stored your file and click scan. Once the scan has been completed you will notice that the files have been listed on the basis of Name, Type, Last Modified and Size. Click on the file you want to recover and then click 'Restore Files'.
Pandora Recovery
This is one of the most popular file recovery options in circulation right now. It has a simple interface and is equipped with one of the best wizards to aid you in data recovery. It can also be used across various storage devices like memory cards, USB drives, and external disks apart from the usual Hard Disk. It also features an interesting advanced recovery feature called the 'surface scan', which scans and provide better recovery results than most standard applications.
Free Undelete
As the name suggests, it's available for free and is a good choice for file recovery software. This software can also be used across different storage devices that can be connected to your PC. One of its unique aspects is the 'folder drill down' feature. This feature makes searching for your files less cumbersome and easy to spot.
Recuva
This is another file recovery application that is popular with the masses. The software is available for free and has an easy to use interface. It can be used across most Windows platforms and file recoveries are even successful on Apple iDevices. It also has many advanced recovery and search options, which easily makes it one of the most sought after options for data recovery.
Undelete Plus
This is an effective data recovery application. It may not be in the same league as some of the other recovery software's, but can do a good job nevertheless. It can be used on most Windows platforms and can recover files from various storage devices that can be connected to your PC. It searches and scans most of the files with popular extensions. Good and safe choice!

CCIE Certified Professionals and Pay Rates

By Allan Castro  

Photo:4.bp.blogspot.com
 
As the upsides of managed network services have come as an essential need for business organizations and entities, the demand for certified IT Professionals has dramatically increased, with employers and organizations more inclined to hire individuals who can actually deliver results at pegged expectations, basing their performance capacities on the certifications and accredited skills-qualifier documents they hold.
Even though an IT Professional is not exactly a graduate of an IT-specific course, different certificates and accreditation credentials have done their part in propelling countless professional IT careers into being, with the Cisco Certified Internetwork Expert (CCIE) certificate being one of the more respected and highly valued.
Given the fact that a CCIE Certificate holder has demonstrated the capacity and ability to work in the most complex of network systems, the average holder is bound to have the highest salary rates in the Information Technology industry.
CCIE Certified Professionals and their Pay Rates
Unofficially considered as the "doctorate in computer networking courses or certifications", a CCIE Certificate holder takes on duties covered by the certificate's covered tracks, including working technical knowledge on data center management, service provider operations, security implementation, online-based voice services, wireless network management, routing and switching operations, storage networking and service provider operations.
Generally, it isn't strange to hear of Certified professionals earning six figure salaries, typically starting at a "humble" $150,000, as it is also not strange to hear of bigger pay rates being given to CCIE Certified professionals who specialize in particular network management disciplines.
Though salaries are dependent on one's geographic location, thereby dependent on a given location's current economic and entrepreneurial standing, instances of some individuals earning as much as $100,000 is known to be, but not altogether a "deal breaker" when talking about the financial prospects available for such qualified personnel.
Is a CCIE Certificate enough to ensure high salaries?
As it is true that a certificate holder is bound for a lucrative position in the IT industry, it has to be said that matching the credentials that pieces of paper gives with solid experience proves to be the ideal match that truly defines ideal standards.
Given the ever dynamic shifts and changes in the IT arena, an experienced CCIE holder is more likely to earn more than an inexperienced one, with just and easy-to-understand cause.
Apart from having the right training and the working-model understanding of today's network systems, an experienced professional's skill set is backed by actual hands-on experience in the real field.
As such, it is highly advised for IT professionals intent on garnering their CCIE Certificates to consider building up their professional work experience portfolios, in improving their employment prospects and building up their knowledge and experience skill sets.

Allan is part of the development team at https://presidential-training.com/, a top CCIE training firm providing extremely competitive service offerings in the form of CCIE Rack Rentals, Virtual Mock Exams, and Workbooks. When one looks for topologies mirroring the exact specifications of CISCO, there should be no compromise. Please visit our site for more information

What to Look for in a Wireless Access Point

By David W Christie 

Photo: img.systemaxdev.com
 
Wireless networks have been one of the technologies that have revolutionised data networking, both for the home user and business networks. A wireless network in the home gives us mobility so that we are not tied to a single location within the home. Modern wireless routers have a wireless access point built in and usually give the flexibility of allowing both wired and wireless connections.
So what should we look for when choosing a wireless access point? There are many models to choose from, offering a wide range of supporting protocols and standards. They also come within a wide price range depending on the networks they are designed to support. Prior to the introduction of Wireless Access Points, early wireless networks were referred to as Ad Hoc networks, because two or more wireless-enabled devices communicated with each other when both within range, rather like a Bluetooth network. Ad Hoc networks are fine when there is a common theme such as gaming, but are not particularly good for general Internet connections. Wireless networks using Wireless Access Points have a number of distinct advantages, such as the ease at which they can be secured given the right security protocols and another advantage is the ability to have multiple access points supporting multiple WLANs all connected to the same wired Local Area Network.
Wireless Access Points have many diverse applications these days, and these range from providing wireless access to a corporate LAN, and when multiple access points are used then roaming becomes possible. A WLAN Controller is normally used to manage a group of APs within a LAN environment. Some Wireless Access Points are used to allow the public to connect to the Internet such as in hotels, coffee shops and even supermarkets. It is wise when using these public wireless networks to have good security on your PC as security is not a great feature of these applications. Access points used in this way are often referred to as wireless hotspots.
The common wireless standard is the IEEE 802.11 standard which has 3 main categories, namely 802.11a, 802.11b and 802.11b. The IEEE 802.11a standard is designed to operate within the 5Ghz UNII wireless band, while the IEEE 802.11b and g standards operate within the 2.4Ghz ISM band. The IEEE 802.11g standard can provide speeds of up to 54Mbps and is backward compatible with the IEEE 802.11b standard. With diversity antennas supporting the IEEE 802.11n standard, speeds of up to 300Mbps can be achieved. Don't let these speeds fool you as a lot of the bandwidth is taken up by the sophisticated overhead associated with these networks. Typically a 54Mbps connection will give you a TCP/IP throughput at a maximum of 25Mbps.
A very important consideration when deploying a WAP is security in the form of authentication to ensure only trusted client devices associate with the access point and encryption to ensure any data you send across the radio environment is secure from eavesdropping. All the client devices are sharing the same wireless environment and have access to that network through the use of CSMA/CA (Carrier Sensed Multiple Access with Collision Avoidance). Any wireless client within range of the radio signal will be able to detect the presence of a wireless access point and may try to associate with it. When the right security methods are employed, only clients with the correct authentication credentials will be able to associate and then have access to the radio channel.
When choosing a wireless access point check the security features that are supported. The older less secure methods include WEP (Wired Equivalent Privacy) with normally 64 or 128-bit encryption keys. These methods can be compromised by individuals who have the knowledge. You should at least be looking for device that supports WPA (Wi-Fi Protected Access), or better still the more advanced WPA2 standard. In the corporate environment a WAP is often protected by means of the IEEE 802.1x standard which uses a server to authenticate clients before they are allowed access. The Ethernet switch to which the access point is attached will challenge a device and forward information received to a server like a RADIUS (Remote Access Dial In Use Service) server, who will inform the switch whether access should be granted or not.
When determining which access point you should buy, you have to firstly decide on what it is to be used for. How much throughput do you need for your applications? Will a 54Mbps network be enough or maybe your would like or need to have the IEEE 802.11n standard running at 300Mbps. Does the wireless access point need to be mounted on a wall or ceiling, or is it just to be positioned on a desktop? Will the existing antenna provide sufficient gain for your needs, or does the antenna need to be detachable to allow a more suitable antenna to be used. How and where will the WAP connect to the wired network and what level of security will you need?
Finally, something we haven't discussed so far, can you use an access point with a power adapter or does the device need to be powered over the network from a PoE (Power over Ethernet) Switch or even a Power Injector?
Does the device you have chosen have a simple intuitive Graphic User Interface for configuration and monitoring, or do you need configuration skills because the device is configured from a command line interface?
The more features and functions you need with your WAP, the more the unit is likely to cost you.

Is Apple's iPad the Clear Choice for All Tablet Enthusiasts?

By Jackie Munton

The so called 'cult of apple' arguably began its reign as first choice for electronics consumers, with the release of its ever popular '1984' advert. From the adverts indirect attack on IBM's corporate prison style image, more and more people decided to side with the apparent freedom fighting and creative style of Apple. But how free does buying from Apple make you?
Primarily Apple products limits cross functionality through differentiating software and hardware to stop people from linking none Apple devices. Additionally, Apple encases their products in such a way that even removing your battery would incur a void warranty. This forces you to always turn to Apples extremely high prices in order to service every one of your electronic needs. Is this the freedom Apple was referring to?
However, regardless of Apples obvious attempts to force customer retention, they have done an incredible job of making this seem irrelevant to most consumers. Within three days of release, Apple posted sales of over five million of its latest iPhone 5 and these impressive results have not only been seen on their mobile phones.
The Telegraph shows a 14% increase in tablet users from last year with one in four smartphone users using a tablet this year. A large influence on this has been from Apples own tablet, the iPad. Apple have shown over 84 million iPads have been sold with CNN suggesting these figures resulting from a huge 88.3% of all tablet market share owned by Apple. But how long will this dominance last?
Recent years have seen a high level of competition in the tablet market. Apples largest competitors utilise the ever growing popularity for Android and Windows operating system (OS) devices. This has allowed companies such as Samsung to reap the rewards for those who have a dislike for Apples controlling nature, wishing for a more customisable and cost effective experience.
Samsung is not alone in their attempt to pinch Apple's loyal customer base. Amazon has also released their own take on a tablet with the Kindle Fire HD, offering tablet functionality at lower prices. Although this is unusual for an online marketplace to delve into, with the shocking success of the Kindle Paperwhite, and its revolutionising effects on reading in the 21st century, the tablet world seems an attractive focus for the online retailer.
History has shown that tablets have been around for a long time with the first ever patent for an electronic tablet being granted in 1888. But only in the past decade has technology really allowed tablets to shine above traditional personal computers. The masses of features and functionality have allowed tablets to become a strong competitor for the future of personal computing and have seemingly made tablets the primary focus for 2012/2013. Currently, Apples hold on the industry is the strongest, but with ever growing competition from cheaper and more feature packed devices, the duration of their stay at the top of the tablet choice will depend on Apples innovation and first in industry developments.

CISS - Benefitting Your Printer

By Tocab Jackson  

Photo: inksystem.com
 
In today's modern world of computers, most of us have access to a printer. Whether it is at home, at your place of work, or at the local library, if you need to use a computer, you can be assured that the need for a printer will follow close behind. As important and as useful as these printers are, they have one major flaw - ink usage. Heavily used printers require a lot of ink, which equates to a lot of money - unless you have discovered Continuous Ink Supply Systems (CISS).
What is CISS?
CISS, or Continuous Ink Supply Systems, have totally revolutionized the way in which we supply printers with ink. Traditionally, you would fit black and color cartridges into an inkjet printer and replace them when they run out of ink - CIS systems mean that you never have to worry about changing a cartridge again. By connecting a CISS, Epson printers, Canon printers, and every other brand of printer, can be supplied with a constant stream of ink, allowing you to print until your heart's content.
A CISS works by delivering a constant flow of ink to a special cartridge that is connected via a capillary system to external tanks. When the tanks are near empty (you can purchase 4 to 8 tanks depending on your printer), you simply fill them back up with the correct color; it really is that simple!
This type of set-up is now being used by more and more people and comes with a number of tremendous benefits.
Continuous Ink Supply benefits
The most obvious benefit of CISS is the money that can be saved. Using a Continuous Ink Supply means that you do not have to worry about buying cartridges, or throwing away cartridges that may still contain ink. Ink is bought and sold in bulk and not in cartridges, which makes it much cheaper, so much so, that users estimate savings of over 90%!
Using CISS, Canon and other printers suddenly become much greener. Not in actual color, but from the drastically reduced amount of packaging and plastic that is wasted.
Many people also see CISS as a much more hassle free method of getting ink as it means not having to track down a cartridge that matches the make and model of your printer. The ink CISS ink is also generally of a higher quality than that used in cartridges.
If you are someone that finds yourself changing cartridges on a regular basis, you should think about switching to a Continuous Ink Supply today!

Find out how you can save money with Ciss Epson ink supply. With a continuous ink supply system you save money and the headache of having to replace ink cartridges on a normal basis. We also carry Ciss Canon.

Do Dell Blade Servers Make Sense for Certain Companies?

By Alex Bardi  

Photo: images.bidorbuy.co.z
 
The invention of blade servers was a significant advancement in hardware technology, but an advance in IT technology that benefits one company does not always benefit another. Dell blade servers offer compelling IT advantages and economic benefits to companies whose needs the hardware is designed to address. Nevertheless, how does one know if its company has the needs that Dell blade servers address? If it needs to accomplish some of the things below, then it does.
Creates Room in the IT Department. These models take up less room than tower models and rack mounted models because they are smaller, and are housed in a compact chassis. This compressed storage design increases the amount of floor space in the IT department. Companies that need to get the biggest return on a rented office can benefit from installing blade units.
Increases Energy Efficiency. Because the chassis combines all the energy it needs of these models into a compact unit, it saves the owner more energy than it would from operating several tower models or rack-mounted models. If a company has recently implemented a green initiative, using blade models is an excellent way to support the initiative and improving energy efficiency.
Reduces IT Cabling. If an office has unsightly and potentially dangerous IT cabling running across the floor, up walls, and through ceiling panels, implementing Dell blade servers that limit IT cabling to a single unit can help solve the problem. Types of cabling that the hardware reduces include cabling for Ethernet connection, SANS connections, and cluster connection.
Fills the Chassis. Buying a chassis and only filling it with a few units is not economical. Consequently, companies that are considering investing in configured Dell blade servers should ensure the need to deploy enough units to justify the investment. Otherwise, implementing tower models or rack-mounted models may be more sensible.
Reduces IT Management Cost. These models have several features that can reduce the cost of IT management, such as a user-friendly interface that is used to manage all of the units in the chassis, and centrally controlled configuration management, operation status monitoring, and fault monitoring. If a company needs to decrease the IT budget, implementing the hardware is a viable strategy for lowering cost in the long-term.
Expedites Hot Swapping. Blade models can be quickly hot swapped while the system is up and running. In fact, timed hot swapping tests have demonstrated that multiple units can be swapped out in less than one minute. If availability is integral to a company's business, implementing blade models is a sensible choice.
Conclusion
Using blade models offers several advantages, including increased space in the IT department, increased energy efficiency, reduced IT management cost, and expedited hot swapping. If a company has some of the IT needs listed above, using Dell servers in the blade configuration could offer benefits that decreases IT expenditures and increases network flexibility. For more information about the benefits of blade models, contact a vendor of Dell blade servers today.

As long as the IT network has needs that can be met by implementing Dell blade servers, implementing blade configured Dell servers is an excellent move.

However, with the huge selection of multimedia notebooks available these days, it is possible to get your hands on a top-rated portable computer for an affordable and inexpensive price. That being said, the best gaming laptops are obviously the most expensive, but the cheap notebook computers reviewed here are all great options to consider as well.

How Do You Connect Two Monitors To One Computer?

By Jason Smythson 

Photo: cdn4.digitaltrends.com

After years working in the computer industry, a question I was frequently asked was. How do you connect two monitors to a computer that only has one VGA socket? The answer is not as straightforward as you may think. You can add a VGA graphics card that offers dual outputs, these can cost around sixty pounds and if you are not confident at installing a PCI card you will also need to pay your local computer shop to install into to the motherboard of your computer, they will probably charge you twenty pounds to do this.
Another solution is to use a VGA splitter. There are a few types of monitor splitter available. They range from basic 2 into 1 cables costing around 10 pounds right up to complex mains powered switches that can run multiple monitors. The basic 2 into 1 VGA splitters are ideal for most peoples needs. They have a male 15 pin VGA plug which you would place into your existing computer VGA socket, the other end of the cable will divide into two female VGA sockets. You simply plug your two monitor cables into these sockets and you are ready to go.
The best type of VGA Splitters are the mains powered versions. This actually amplify the signal before they send it to your monitor. The mains powered splitters are a standalone box that has an input socket from the computer and multiple output sockets to feed your monitors. This can be very useful as many VGA graphics cards do not produce enough power to run multiple computer monitors. You will certainly require a mains powered splitter if you intend running more than two monitors of if you are using longer VGA cables. You can purchase a basic mains powered VGA monitor splitter from as little as twenty five pounds in the United Kingdom. You will obviously pay more if you require more than two additional ports.
VGA splitters can be used on both laptop and desktop computers. The are frequently used to power projectors for presentations. A VGA cable has 15 pins arranged in 3 rows of 5 pins, the plugs have two small thumb screw on either side, these are used to secure the cable into the computer and monitor. It's important not to confuse VGA with DVI which is also found on many computers, DVI is a larger plug which has a wider spade type connection to the side, it can have anything from 17 to 29 pins.
