A Webopedia Definition. Main » TERM » C » By Vangie Beal. A computer is a programmable machine. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well- defined manner and it can execute a prerecorded list of instructions (a program). Modern Computers Defined. Modern computers are electronic and digital. The actual machinery — wires, transistors, and circuits — is called hardware; the instructions and data are called software. Common mass storage devices include solid state drives (SSDs) or disk drives and tape drives. A computer program is a list of instructions that tell a computer what to do. Everything a computer does is done by using a computer program. A computer program is written in a programming language. Some examples of computer. New computer program aims to teach itself everything about anything. What is a Computer Program? Most software programs have versions that run with various operating systems. I’m not sure I follow the article’s definitions of two kinds of computer programs. Computer program, a series of instructions that a computer can interpret and execute; programs are also called software to distinguish them from hardware, the physical equipment used in data processing. An introduction to what computer programs are for those who do not write them. A computer program is one type of software. Cite This Article; Recent Questions; Ask A Question; All Questions; Tags.

The Department of Veterans Affairs on Monday sought to clarify VA Secretary Robert McDonald's controversial comparison between the VA's wait times and wait times at Disneyland, by saying veterans themselves have. Input device: usually a keyboard and mouse, the input device is the conduit through which data and instructions enter a computer. Output device: a display screen, printer, or other device that lets you see what the computer has accomplished. Central processing unit (CPU): the heart of the computer, this is the component that actually executes instructions. In addition to these components, many others make it possible for the basic components to work together efficiently. For example, every computer requires a bus that transmits data from one part of the computer to another. Computer Classification: By Size and Power. Most people associate a personal computer (PC) with the phrase computer. PCs are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. Personal computers at home can be used for a number of different applications including games, word processing, accounting and other tasks. Computers are generally classified by size and power as follows, although there is considerable overlap. The differences between computer classifications generally get smaller as technology advances, creating smaller and more powerful and cost- friendly components. Personal computer: a small, single- user computer based on a microprocessor. In addition to the microprocessor, a personal computer has a keyboard for entering data, a monitor for displaying information, and a storage device for saving data. Workstation: a powerful, single- user computer. A workstation is like a personal computer, but it has a more powerful microprocessor and a higher- quality monitor. Minicomputer: a multi- user computer capable of supporting from 1. Mainframe: a powerful multi- user computer capable of supporting many hundreds or thousands of users simultaneously. Supercomputer: an extremely fast computer that can perform hundreds of millions of instructions per second.
