teleprinter-style keyboards became the main input device for computers. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters‚ numbers or signs (characters)‚ other keys or simultaneous key presses can produce actions or computer commands. Despite the development of alternative

KEYPOINT 1: Computer Literacy (Literacy-ability to read/write) Introduction: • How many people in this classroom learn to use computer? As I look around‚ no one in this classroom‚ don’t use computer in their offices. • We are all students of AIC‚ and most likely gone to different basic computer course. • Does studying computer affect the way we communicate? And if so‚ is this a bad thing? Development • As our society‚ increasingly dependent on computers to take care

Computer Multimedia Sam Quesinberry Computers have come a long way very fast since there start in the 1940’s. In the beginning they were mainly used for keeping financial records by banks and insurance companies‚ and for mathematical computations by engineers and the U.S. Military. However‚ exciting new applications have developed rapidly in the last few years. Two of these areas is Computer Graphics and sound. Computer graphics is the ability of the computer to display‚ store and transmit

years. The modern computers we are all familiar with can trace their roots back to simple computational machines that seem far removed from what we think of as a computer today. Simple Computers • By definition‚ a computer is any device capable of performing mathematical equations or calculations. Therefore‚ many simple devices such as an abacus (which dates back to at least 300 BCE) or a slide rule (first made in England in the 1630s) are the forerunners of today’s modern computers. The Calculating

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language. Source code is
