A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks.
What Is a Computer? A computer is a programmable device that stores, retrieves, and processes data. The term "computer" was originally given to humans (human computers) who performed numerical calculations using mechanical calculators, such as the abacus and slide rule.
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 an electronic device that processes data according to instructions provided by software programs. It takes input (data), processes it using a central processing unit (CPU), stores information, and produces output (results) to perform various tasks.
A computer is an electronic device wherein we need to input raw data to be processed with a set of programs to produce a desirable output. Computers have the ability to store, process, and manipulate data.
A computer is a programmable machine capable of executing a programmed list of instructions, accepting input, and returning output. While many mechanical devices can technically function as computers, the term commonly refers to digital electronic computers.
A computer is a programmable machine that responds to specific instructions and uses hardware and software to perform tasks. Different types of computers, including desktops, laptops, tablets, and servers, serve various purposes based on portability and power.
Computer - Technology, Invention, History: 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. Specific methods to make automated calculation more practical, such as ...
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. Computers come in many different shapes and sizes, from smartphones to supercomputers weighing more than 300 tons.
Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The discipline of computer science includes the study of algorithms and data structures and artificial intelligence.
Computer - History, Technology, Innovation: How did the abacus lead to modern computers? The earliest known calculating device is the abacus, dating back to at least 1100 BCE and still in use today, particularly in Asia. The abacus showed that calculations could be represented physically and manipulated systematically. Its use of discrete bead positions—on or off—anticipated the digital ...
Personal computer, a digital computer designed for use by only one person at a time. A typical personal computer assemblage consists of a central processing unit, which contains the computer’s arithmetic, logic, and control circuitry on an integrated circuit; computer memory; and various peripheral devices.
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). Traditional histories of computers assign generations on the basis of technology.
A computer is a device for working with information. The information can be numbers, words, pictures, movies, or sounds. Computer information is also called data. Computers…
Generally, a computer is any device that can perform numerical calculations—even an adding machine, an abacus, or a slide rule. Currently, however, the term usually refers to…
Computer science - Architecture, Organization, Algorithms: Computer architecture deals with the design of computers, data storage devices, and networking components that store and run programs, transmit data, and drive interactions between computers, across networks, and with users. Computer architects use parallelism and various strategies for memory organization to design computing systems ...
