Computer Network Internet File Pdf Computer Network Duplex A computer is a programmable device for processing, storing, and displaying information. learn more in this article about modern digital electronic computers and their design, constituent parts, and applications as well as about the history of computing. A computer is a machine that can store and process information. most computers rely on a binary system, which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information.
Network Internet Pdf The history of the solving of these problems is the history of the computer. that history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. Ada lovelace is considered the first computer programmer. even though she wrote about a computer, the analytical engine, that was never built, she realized that the computer could follow a series of simple instructions, a program, to perform a complex calculation. Eniac, the first programmable general purpose electronic digital computer, built during world war ii by the united states and completed in 1946. the project was led by john mauchly, j. presper eckert, jr., and their colleagues. Computer software is divided into two basic types—the operating system and application software. the operating system controls how the different parts of hardware work together. application software gives the computer instructions for doing specific tasks, such as word processing or playing games.

Charles babbage, english mathematician and inventor who is credited with having conceived the first automatic digital computer. he designed two calculating devices, the difference engine and the analytical engine, neither of which were fully built. learn more about babbage in this article. By the second decade of the 19th century, a number of ideas necessary for the invention of the computer were in the air. first, the potential benefits to science and industry of being able to automate routine calculations were appreciated, as they had not been a century earlier. A virus consists of a set of instructions that attaches itself to computer programs, usually in the computer’s operating system. typically, the infected programs continue to perform their normal functions, but they also begin to execute the virus’ instructions behind the scenes. Multitasking, the running of multiple programs (sets of instructions) in one computer at the same time. multitasking is used to keep all of a computer’s resources at work as much of the time as possible. it is controlled by the operating system. learn more about multitasking in this article.
