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. These programs enable computers to perform a wide range of tasks.
Apr 9, 2024 · 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. The term was later given to mechanical devices as they began replacing human computers.

May 31, 2023 · 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.
At a high level, all computers are made up of a processor (CPU), memory, and input/output devices. Each computer receives input from a variety of devices, processes that data with the CPU and memory, and sends results to some form of output. This diagram visualizes that flow:
This unit provides an overview of how computers work. Learn about transistors, logic gates, logic circuits, the CPU, memory, and the file system.
A computer is a machine that uses electronics to input, process, store, and output data. Data is information such as numbers, words, and lists. Input of data means to read information from a keyboard, a storage device like a hard drive, or a sensor. The computer processes or changes the data by following the instructions in software programs. A ...
