Computer Monitor

A computer monitor is the viewing display of a computer. People often get confused and call the monitor the computer. The reason they get mixed up is because the monitor is the unit that people look at and is usually quite big. There are two types of monitors, these are the CRT (Cathode Ray Tube) and the LCD (Liquid Crystal Display). The CRT is the older of these two types and is very chunky unlike the LCD monitors which are very thin.

A computer monitor connects to the computer's video card. The information is sent from the computer, processed by the graphics card and then sent through the cable to the monitor where it becomes visible. The monitor does not store information but only displays what is sent from the computer.

This means a computer can run without a monitor but there would be no point as the user cannot see anything he does.

The CRT monitor connects through the VGA (Video Graphics Array) port on the graphics card while the LCD monitor can connect either through the S-VGA port or the DVI (Digital VideoInterface) Port.

A pc monitor is measured in inches. Common screen sizes are 15", 17", 19", 20", and 22". Some screens reach sizes of 40" or more but this is rare. A monitor is measured from one corner diagonally to the other. This gives it's size in inches.

The LCD monitors which are more recent then the CRT monitor are very useful in saving desk space and are usually easier on the eyes. LCD widescreen monitors have also become popular and these stretch further across. The widescreen monitor takes a while to get used to but once you do it feels much better. Not only can you watch movies in full capacity but you can sometimes view two A4 pages at the same time and it is much easier to turn your head sideways then up and down.

What is a Sound Card?

A computer sound card is an additional card that is often included in the motherboard. This computer component is not compulsory but it is useful to have as most programs use a sound card.

A computer sound card is used by a computer for music, sounds during applications and entertainment (TV, movies and games). A typical sound card usually has four ports. The largest port is the Midi/Game port, which is used for connecting a joystick or gaming controller to. The other three ports look similar and are generally green, pink and blue.

Underneath each port will be a small engraving of what each port does. The pink port is for a microphone which can record sound to the computer. The green port is line out and this is where the speakers are connected to produce sound from the computer. The blue port is line in and this is for connecting a CD-player or cassette tape to the computer.

Computer Video Card

The computer video card is a very important component in a computer. Without it you would not be able to send any information to the monitor. Your computer can be running fine but if you can't see anything on the monitor then it is basically worthless. So can you see the importance of the video card and choosing one that suits your needs?

A computer video card is placed in the motherboard, where it transfers video signals through a cable to your monitor. The video card can either be built into the motherboard or be a separate card that is placed in either the AGP or PCI-Express Slots.

The computer graphics cards major job in a computer is to convert graphic patterns into signals for the monitor's screen. However in recent times as the graphics card has become more advanced it has taken some of the jobs previously assigned with the CPU and through a graphics pipeline adds 2D and 3D effects and it also adds textures.

A computer video card has three memories chips, a processor fan and process heat sink and etc.
