Computer Network Practical File Pdf 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. 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.
Computer Network Internet File Pdf Computer Network Duplex 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. 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. Personal computer (pc), a digital computer designed for use by only one person at a time. 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.
Computer Network Pdf Computer Network Network Topology Computer, programmable machine that can store, retrieve, and process data. a computer consists of the central processing unit (cpu), main memory (or random access memory, ram), and peripherals (e.g., a keyboard, a printer, disc drives). Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. Mainframe, digital computer designed for high speed data processing with heavy use of input output units such as large capacity disks and printers. mainframes have been used for such applications as payroll computations, accounting, business transactions, information retrieval, airline seat. Digital computer, any of a class of devices capable of solving problems by processing information in discrete form. it operates on data, including magnitudes, letters, and symbols, that are expressed in binary code—that is, using only the two digits 0 and 1.
