Monitor Technology Explained
Monitor types
CRT (cathode r
ay tube) monitors are a now archaic display technology that was popular even into the 21st century. A cathode ray tube contains multiple electron guns, which fire electrons through a vacuum onto phosphor "pixels". Three colours of phosphor "pixels" are present (red, green and blue), and deflection by a magnetic field determines which ones will be lit. Although colour reproduction and contrast were excellent in later models of CRT monitor, modern
LCD monitors (see below) are vastly thinner and lighter, whilst providing outstanding contrast ratios, good colour reproduction and response times. A list of now-redundant terms related to CRT monitors can be found in the final section of this PC Monitors article.
History of the Computer - Computers and Technology
The volume and use of
computers in the world are so great, they have become difficult to ignore anymore. Compute
rs appear to us in so many ways that many times, we fail to see them as they actually are. People associated with a computer when they purchased their morning coffee at the vending machine. As they drove themselves to work, the traffic lights that so often hampered us are controlled by
computers in an attempt to speed the journey.
