The demand of LCD (Liquid crystal display) monitors is rapidly growing in the market. With the advancement of technology LCD are quite familiar to computer users and we can see most of them are using LCD. It would be a challenge for LCD manufacturing companies to fulfill the growing demand of LCD in the market.

Some comparison between LCD monitor and CRT monitor is given below

1. LCD panels are only an inch thick without including the stand. These consume less power and don’t radiate a lot of heat when used, unlike CRT monitor.

2. Their digital display is sharper and produce good quality picture as compare to CRT monitor.

3. An LCD monitor is slim and comes in a very compact configuration. They can be fit easily into any less vacant part of the room or any where. They are very suitable for small offices or homes

4. But its difficult for everyone to afford LCD display because LCD display screens or monitors are quite expensive as compare to CRT

5. LCD screens or displays are very sensitive and should be handling with care. They are not suitable for minor used.

6. As far as moving images or 3D images are concern, LCD screen are blurry and unclear. Hence, someone prefers CRT over LCD screens. Graphic designers also prefer the CRT over the LCD. Not only that, the color gradations are not clear in the LCD panel, and it causes problems in differentiating between darker shades, creating practical problems for graphic designers.

Among the biggest names in computer and technology is Dell. The expanse covered by Dell is so great that it actually develops and markets software up to computer gadgets and accessories such as computers, routers, networks, even switches, among others. From its early years, Dell has really grown stronger as evident with the 95, 000 employees it has right now in the year 2008. During the 1980s up until the 90’s, Dell was able to achieve immense success by becoming achieving the top spot in terms of sales. Although it’s been a decade since those years, Dell has consistently retained its place despite the fact that it is a second tier with Hewlett-Packard obtaining the top spot in 2008 computer sales.

Michael Dell is the force behind the inception of this technological icon. He began to found the company while he was still a student back in the University of Texas. It was in 1984 when Michael decided to run his own business, using the name PC’s Limited during that time. He started off with just a thousand dollars and from then on, Dell emerged as a result of all his hard work and technological passion. In his early years of being a computer entrepreneur, Michael Dell decided to sell various IBM computers which are considered to be PC-compatible. These computers are built right out of stock components.

During that time, Michael thought that it would be a good venture to try selling personal computers to direct customers. He thought that this strategy will help make computers more attuned to the needs of every individual. In his mind, he saw this strategy as a very helpful way of making PC’s Limited a very effective computer program from users as it learns from what previous clients have suggested with the earlier version of the computer products. True enough, his efforts paid off and his computer business soon began to boom. Because of the overwhelming success he experienced, Michael Dell finally decided to quit school and focus instead on making his business a full-time venture.

Just a year after it began, PC’s Limited launched its “Turbo PC” back in 1985. The design of the computer is specific to the said brand. At that time, the turbo PC already ran via Intel 8088 and also has a functional speed set at 8MHz. To be able to reach bigger and better markets, Dell advertised on computer magazines which are nationally distributed. Moreover, Michael Dell also allowed customers to make their own specifications when it comes to what they want for their computers to look like. Indeed, Michael Dell was able to meet two of the most important things computer users want: a customized platform at an affordable price.

Within three years after that, PC’s Limited once again opted for an expansion venture. It was in 1988 when the company finally changed its previous name to what we now know as “Dell Computer Corporation.” By this time, the company’s capital already increased by 50 million dollars and its shares has also started to pick up. From here on, Dell established itself as a technological pioneer.

An essential component to any computer, be it a desktop, laptop or notebook computer, keyboards have generally been a fixed device directly connected to the control of the computer. The spaghetti junction worth of cables, wires and plugs was not only unsightly, but severely limited the options of the user as well as posing safety risks.

In a bid to give the user more freedom, and to help save on space, wireless keyboards have became increasingly common and popular. It is a testimony to the value of wireless keyboards that they are now being sold as an included component of the machine, as opposed to as an accessory.

Many of the early prototypes of wireless keyboards did not have a particularly successful career, due to limited battery lifespan and a constant need to replace the batteries soon irked consumers. Advances have now been made which have ensured that the longevity of the batteries are ensured. Whilst keyboards in general are always assumed to be the QWERTY model so often associated with desktop and laptop computers, wireless keyboards have became increasingly common amongst handheld devises such as PDA and other media players.

These wireless keyboards are used to more conveniently play and manipulate media, and include fast foward, rewind, play features as well as volume control and mute function. Miniature QWERTY keyboards which are fully wireless are also available for the likes of PDAs and other hand held devices so as to allow the user a greater ease for entering data and contacts.

Other useful features include a button which can be used to engage the internet browser, and another dedicated to email. Rather than being a traditional keyboard minus the cords, wireless keyboards are a clear mark in the next stage of evolution of keyboards, designed to be more user friendly as well as of greater, practical benefit to the user. Many wireless keyboards also come with a pointer device akin to he standard mouse which is designed to eliminate the need for a traditional mouse, and this further increases the freedom for the user.

Concerns have been raised however as to the actual security of the wireless keyboards. Wireless keyboards in order to actually work, need to transmit signals from the device to the computer and this has meant that they are open to abuse and exploitation.

Radio frequency (RF) or infrared (IR) signals sent and received from the keyboard and the unit attached to the computer facilitates it to work as wireless keyboard and these can be readily intercepted by hackers. This means that not only can the keyboard itself be compromised, but that the actual integrity of your system can also be compromised as well.

Wireless keyboards are also becoming increasingly eco-friendly, with the latest innovative design feature being the inclusion of solar powered keyboards. This has meant that batteries and plugs are no longer required and has thus guaranteed the smooth operation of the keyboards for a long time to come. With an eco-friendly design, wireless keyboards are fast becoming the latest must have computer item.

Sometimes you might end up seeing that your personal computer is not running as fast as usual. This can be due to various problems but here is how you can make sure that your PC is running as it should. All you need to learn is how to differentiate and have the information linked with anti virus, anti spyware and various other optimization programs out there.

First off we need to understand that we must not turn off our computers with the use of the power switch directly until Windows finished shutting down. There is one exception to this rule though. When your PC simply locks up and the hard drive is not running anymore (you can easily notice this by the fact that the hard drive light is not blinking). That is when you can turn the power off to your computer with the use of the power switch without any harmful effect on the hard drive. The problem is that if you cut the power to your PC directly you can end up with data lost and even damaged Windows files. Only do this when you have no other possibility at hand. This is how you can prevent hard drive defects that are caused by its heads hitting the surface of the disc. If possible first try to recover from crashes by pressing CTRL+ALT+DEL and then press them again in order to reboot your PC.

Another thing you can do in order to maintain the speed of your personal computer and also aid in it working properly is purchasing an UPS (uninteruptable power supply). This will aid it from crashing when power outages happen. In the same time you will see that the computer is protected from high and low voltage occurrences. Any UPS is superior to a surge protector and your PC might end up being saved from most power type disasters that can happen.

Every single month you must remember to run Defragment and Scandisk. This is highly important in keeping the hard drive healthy and will also prevent crashes. One can also utilize Norton Utilities for this if you have it installed. Also, remember that you should keep at least 500 MB free on the drive where you installed Windows. If there is not enough space Windows will start dumping data on your hard drive or it can become really slow, without warning you in some situations. Alternatively you can utilize Cleansweep (also included in Norton Utilities) in order to clean your drive. If you decide to use it keep in mind that you should not delete any shared file until you have a backup setup. All cleaners out there will have problems with knowing whether or not any other program uses the files you might end up deleting automatically.

Another common mistake that people do is allowing a lot of programs to load up when it starts. This translates in Windows Resources and memory usage. Every program that is located in the Windows System Tray is working and currently running on your computer. You should close them if you do not use them and configure them not to load when you start up your computer. All other programs that are running in the background can be found by pressing CTRL+ALT+DEL.

Never neglect the existence of a virus checker. Everyone needs one and the best solution is choosing a good anti-virus that also has continuous monitoring. There are also online virus checkers but we do recommend the use of regular anti virus software. Another thing that should not be neglected is the need of a firewall program, especially if you have high speed Internet connections. Such a firewall will keep people that want to gain control of your computer away. There are a lot of such software packages out there and you should do a little research and choose the one that suits your needs best.

Although it is not directly linked to the speed of your computer, you must always remember that backup is essential. you never know when hardware fails or software becomes corrupt and so you end up losing a lot of personal data that might be very important for you or your business. Use at least two separate hard drives and always backup data to zip disks, DVDs, CDs, or whatever you can. You should always save documents as soon as you create them if you can not afford to lose them. Waiting until the next day can be dangerous!

We all use internet to communicate with our loved ones. It has now become one of the most integral source for getting in touch with the people around the world. There were times when we were amused to hear the voices of our friends and relatives who stayed at distant places. However the internet has created an immensely efficient platform for us where we cannot only talk or message our loved ones but can also see them while talking or chatting. Web cameras are an extremely appealing devices which help us broadcast our videos through the internet.

These devices are also called webcams and are largely used by the internet surfers who extensively use the instant messengers and video conferencing applications. It is a small camera which is used to capture images. These images can be accessed through the web based applications and instant messengers. The main purpose of these cameras is to capture the images of the person sitting in front of the PC or laptop and transmit it over the internet on the screen of the other person with whom the user is chatting. These devices are generally low resolution digital cameras which capture the images. These images are then uploaded on the web server at regular intervals and sometimes also continuously. These are small in size and generally very compact and stylish. The webcams are fixed either on the PC or laptop or are attached to a dedicated hardware.

These Web cameras are really exciting and beneficial. With them one can have an incredible experience while chatting with friends and family members. It gives a feeling of having a face to face communication with one’s acquaintances. These are also very useful for educators in case they want to give lessons to their students by taking them on virtual education trips. They are being used widely by the people across the world.

These web cameras are connected to the personal computers and they act like web- enabled camera only with the help of the certain specific software. An enhanced application program is required to transfer the video or image files over the web in continuous streams. The instant messengers support video conferencing and live video chatting which can only be done with the help of a web cam.

Have you ever experienced an annoying problem with your computer that you just could not get sorted out on your own? Most people have, and it can be completely frustrating when you are on a schedule trying to meet a deadline. Computer consultants/technicians are expensive even for the most basic of tasks, and calling one each time you have a simple problem can break the bank pretty quickly. However, if you can read simple directions and follow instructions, then it is likely that you can get all the help you need with your computer problems just for the asking.

So how is this possible and where do you need to go? Just visit one of the thousands of computer forums online and you will have hundreds or thousands of people willing to help you out with whatever problem you may have. Most of the minor issues or concerns that you have can be solved by posing a simple question to the many willing participants of the forum. Despite the cynical thinking of some, people are naturally helpful and computer forums are a great place to get help. Even if you have a major issue, there are some participants on forums who will go out of their way to help you get it resolved.

Considering the helpfulness of many of the participants on computer forums, you may be wondering why these individuals choose to help others who need it. There are probably thousands of reasons, but some of the main reasons computer forum participants are willing to help are:

1. People generally like to help others - it gives them a sense of purpose and usefulness

2. They may be “paying it forward” - someone helped them out when they needed it

3. They may have a type of symbiotic relationship with the computer forum - they provide help in exchange for advertising their business and gaining new clients

The third reason is the probably main reason that many users frequent computer forums and provide help. In addition to generally feeling good about helping others, they are afforded the opportunity to promote their business in the process. This works for you and the person providing the help.

They will provide a detailed response addressing your concern; and in return, they are allowed to place a small two to three sentence ad, also called a “signature”, at the end of their post advertising their business. If they are really helpful, many times people will become regular customers/clients and consult them for future issues.

You should be aware that on any forum you visit, there are rules regarding acceptable behavior; and these rules will vary across the different computer forums. So when you join, be sure to read all the rules regarding forum etiquette before you even place your first post.

Computer forums are an excellent way to get the help you need at either no cost or a reduced rate. In addition to getting help, you benefit from becoming a member of a community. And once you have your issue sorted out, hopefully in the future, you will return the favor and lend a hand to another.

To sit down in front of a laptop computer, a model you have never worked on before, and to attempt to figure out how you are going to dismantle it, and then put it all back together again, can be a little unsettling. This is the scenario I have faced many times when my diagnosis have led me to the fact that the laptop in question does indeed need a new motherboard. The motherboard going bad in a laptop is not an extremely unusual occurrence, but it is going to be one of the most expensive hardware repairs that a laptop owner can face.

I always recommend that the owner of the laptop stop and weigh out the options. Is the cost of the repair, (parts and labor), going to be more than a new, used or refurbished replacement laptop would cost? If the repair cost is less than the cost of a new laptop, how much less is it? Is the difference worth taking a chance on the old one? Maybe the laptop, with a new motherboard, will last for several more years. Maybe after the motherboard is replaced a stick of RAM or something else decides to go bad, and a sense of a money vacuum sets in. Ultimately it is up to the owner of the laptop to decide on how to proceed.

In my experience, if the laptop is not all that old and otherwise functions properly, then the cost of parts and labor is just a fact of life and would ultimately wind up being the most economical way to go. I do like to mention also that a new laptop will come with a warranty of usually at least a year. This helps put a stop to the potential money vacuum of repairs, but new laptops can have motherboards go bad also. Then there is the cost of time that it takes for the laptop to be repaired under warranty.

Parts going bad are just a fact of life. It happens in vehicles, home appliances, audio video equipment and computers. Laptops do not sit nice and stationary like a desktop computer does. Laptop cases are built to be quite sturdy from the outside. They are taken into many different environments and often tossed around slightly, but they are designed to be treated this way to a point. Although there are no moving mechanical parts in a laptop, other than fans and drives, the design of the circuitry on a motherboard is actually rather sensitive to heat and power fluctuations.

It is a good idea to keep laptop computers free of dust as much as possible. You should especially make it a point to keep the vent areas of the case that cover the laptop fans free of any form of dust or blockage. A vacuum or even a can of compressed air are adequate for keeping this area free of dust. Only use the proper rated power adapter for the laptop. Be weary of unstable power sources or plugging the laptop into an already over crowded power strip if possible. These simple tips will help to prolong the lifespan of your laptop computer.
