Almost all of us are involved, in some fashion, with computers on a daily basis. Without computers, life would certainly be a lot different. Computers, however, are relatively new on the human scene. Definition of A Computer: A computer may be defined as a machine that can solve problems by accepting data, performing certain operations and presenting the results of those operations under the direction of detailed step-by- step instructions. Such a set of sequenced instructions, which cause a computer to perform particular operations, is called a program. An electronic device for the storage and processing of information. A programmable machine that inputs, processes and outputs data. An electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. CONSTITUENTS OF A COMPUTER All the elements that go together to make a PC fall into one of two categories, hardware or software You simply can’t have one without the other. All the parts of a computer that you can physically see or touch are called hardware. This following list represents a basic set of hardware found in most PCs. PC Case Motherboard Power Supply Hard Disk Drive (HDD) Floppy Disk Drive (FDD) Compact Disk Drive (CDD) Digital Video Disk drive (DVD) Monitors (CRT and LCD) Keyboard Mouse Audio Cables & Wires COMPUTER SOFTWARE Computer software (or simply software) is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software. http://www.techcules.com/definition-of-a-computer-system/
