applications including computer monitors‚ televisions‚ instrument panels‚ aircraft cockpit displays‚ and signage. They are common in consumer devices such as video players‚ gaming devices‚ clocks‚ watches‚ calculators‚ and telephones‚ and have replaced cathode ray tube (CRT) displays in most applications. They are available in a wider range of screen sizes than CRT and plasma displays‚ and since they do not use phosphors‚ they do not suffer image burn-in. LCDs are‚ however‚ susceptible to image persistence

Parts of the Computer & Their Functions Computers are assembled from several key components that make the computer functional‚ called hardware. While most computer users are primarily familiar with the monitor‚ keyboard‚ mouse‚ and other peripherals‚ the most important physical parts of a computer exist inside the case. CPU * The central processing unit processes all of the data that is accessed by the machine. In PCs the CPU‚ or microprocessor‚ is a small silicon chip located beneath the

With the development of Computers and information technology came talk of a new environmentally friendly era. The need to create and store documents on paper would be gone‚ along with the need to travel from city to city to conduct business meetings. The developers of computers sold Government Originations and Corporate America on these cost saving concepts. The promises made by computer developers proved to be somewhat true‚ especially given the wide spread deployment and use of Internet and email

you wouldn’t be able to use your computer‚ unless‚ of course‚ you use your T.V as a monitor. Computer monitors are tremendously made as liquid crystal displays. They are used because they are thinner and lighter and use much less power than cathode ray tube monitors. LCD computer monitors are made in a specific and special type of way. Computer monitors contain raw and treated materials like metal semiconductors‚ phosphorous‚ lead and mercury. Depending on the type of computer screen‚ different

earliest moving silhouette images on June 14‚ 1923. In 1927 philo Farnsworth made the first working TV with electric scanning that could both pickup and display devices. German scientist‚ Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897‚ and which is the picture tube found in modern TV sets. In December 17‚ 1953 RCA designed the first successful color television. In the

There are two types of radiation exposure—82% is from natural resources such as cosmic and solar rays and 18% of the exposure is from man-made radiation. Radiation injures the body by destroying cells and parts of cells. It hinders cells from dividing which gives rise to cells which does not have the ability to reproduce. The reason why

The displays that we see on the monitors are caused by the electrons directed on a phosphor coating on the screen by the cathode gun of the picture tube. To put it simply‚ the computer monitor comprises of a display device along with the circuitry required to form a display using the signals sent by an external source. The computer monitor receives the signals sent by the CPU of the PC
