What is the function of a computer monitor?

The monitor is an essential part of the overall computer system. It is sometimes referred to as the video screen or video display unit (VDU).

There are two main types of computer monitors:

Cathode Ray Tube (CRT) monitors utilize a cathode ray tube to display images. The cathode ray tube is constructed using a vacuum tube, heaters, electron guns, deflection circuits and a glass screen. When electrons are produced within the cathode ray tube, the screen is bombarded with electrons, making it glow and produce an image. CRT monitors resemble older television sets. They are bulky and consume a lot of energy.

Liquid Crystal Display (LCD) screens utilize monochrome pixels when projecting images. The pixels are arranged systematically between transparent electrodes and polarizing filters. Images are formed when the pixels are polarized. LCD monitors consume less energy and offer better graphics quality. They are outselling CRT monitors because they occupy less desk space, provide wide viewing angles and are decreasing in price. The screen sizes range from 17 inches to 60 inches.

What is Motherboard ?

Motherboard is a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to be slotted into.

TIA/EIA 568a and 568b Wiring Color Codes

TIA/EIA-568-B.1-2001 is likely the most commonly used and talked about feature of the specification created in 1988. 568-a is the definition of pin assignments for the the pairs within Category 3 (CAT3), Category 5 (CAT5) and Category 6 (CAT6) unshielded twisted-pair (UTP) cables (eight conductor, 100-ohm balanced twisted pair cabling). The Pin/Pair assignments were named T568A and T568b, both of which define the pinout or specific order the UTP pairs need to be terminated within 8P8C (Eight Position, Eight Conductor) modular connecters, also known as RJ45 connectors. 568-A Color Code Pin #Wire Color 1-White/Green 2-Green 3-White/Orange 4-Blue 5-White/Blue 6-Orange 7-White/Brown 8-Brown 568-B Color Code Pin #Wire Color 1-White/Orange 2-Orange 3-White/Green 4-Blue 5-White/Blue 6-Green 7-White/Brown 8-Brown
