Computer Security | PDF 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. Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. Computer history, technology, innovation: a computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.”. 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.

Fundamental Of Computer Security | PDF | Security | Computer Security Personal computer (pc), a digital computer designed for use by only one person at a time. The first digital computer designed with internal programming capacity was the “baby,” constructed at manchester in 1948. a program is prepared by first formulating a task and then expressing it in an appropriate computer language, presumably one suited to the application. 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 home use, microprocessors, software: before 1970, computers were big machines requiring thousands of separate transistors. they were operated by specialized technicians, who often dressed in white lab coats and were commonly referred to as a computer priesthood.
