Choosing Computer Monitors - How to Avoid Computer Eye Strain

Generally made of carbon frames and glass screens, computer monitors can display color, monochrome and grayscale graphics. There are different kinds of computer monitors depending on their resolution range or display device and they affect your eyes in different ways.

Kinds of computer monitor

CRT or Cathode Ray Tube computer monitors are the most common. They are compatible with Macintosh and PC systems. Although bigger than other monitor types available, CRT monitors are still ideal for home and office use. They are also cheaper.

More expensive flat screen monitors have higher resolution, while LCD computer monitors have wider color ranges and high-contrast displays. For generating faster pixels, TFT computer monitors are available. Most of these computer monitors have built in speakers, mobile bases and security locks.

Your eyes and your monitor

Are you suffering from eyestrain from working long hours in front of a computer? Do not worry. This condition can easily be averted by adjusting your monitor as well as your usual work methods.

You can reduce eyestrain simply by adjusting the font quality and refresh rate of your computer. Make sure that your computer screen is slightly below your eyelevel and at least 20-26 inches from your eyes. Monitors are equipped with lighting systems which you can adjust to reduce glare or any reflections.

Proper cleaning is also important. Monitors that are clean and dust free are less likely to cause eye irritation.

Also take time to rest your eyes even for short periods. Walk away from your computer and look out the window. This can contribute a great deal in reducing computer strain.

Wireless Network Cards

Network cards are the backbone of any network. The Network interface card or the network card is a hardware device that allows a computer to be connected to a network, and through the network to other computers and devices. It is installed in one of the free peripheral connect interface (PCI) slots of a computer and includes a port in which the networking cable is inserted. There are different NICs for different networks even if the computer is the same. For example, if a computer is to be connected to an Ethernet LAN, it must be equipped with an Ethernet network card and if it is to be connected to a wireless LAN, a wireless network card needs to be installed.

Wireless network cards allow you to do away with traditional networking through cables. These are gaining popularity as Wi-Fi hotspots are mushrooming all over the world. Most new laptop computers are now available with pre-installed wireless network cards that are an integral part of the hardware. Wireless network cards that fit into the PCMCIA slots are available for older laptops and similar cards are also available for regular desktop computers.

A wireless network card can communicate only with a wireless router or a wireless access point. It is important that the wireless network card or adapter should work at the same speed and with the same coverage as the wireless router. In addition to the communication software that is embedded in the network interface cards (NICs) ROM, the computer also requires networking software to be installed for the network to be functional. Both the software and the NIC have to adhere to the communication protocols of the network to which the computer is to be connected.

Wireless network cards have increased the mobility by allowing people to work from any location which is Wi-Fi enabled and have also helped in doing away with the hassles associated with installation of traditional wired networks.
