A programmable machine that performs high-speed processing of numbers, as well as of text, graphics, symbols, and sound. All computers contain a central processing unit that interprets and executes instructions; input devices, such as a keyboard and a mouse, through which data and commands enter the computer; memory that enables the computer to store programs and data; and output devices, such as printers and display screens, that show the results after the computer has processed data.

A machine that computes. Specifically, a modern computer is a digital electronic system that performs complex calculations or compiles, correlates, or otherwise processes data based on instructions in the form of stored programs and input data.A device that can receive, store, retrieve, process, and output data.

A computer is a general-purpose machine that processes data according to a set of instructions temporarily stored internally. The computer and all the equipment attached to it are "hardware." The instructions that tell the computer what to do are "software."The software that controls the computer is called an "operating system," and the software that inputs, processes and outputs data for the user is called a "program," "application" or "app." See operating system, application, how to select a computer, stored program concept and computer generations.RAM vs. StorageThe interplay between temporary memory (the RAM) and permanent storage is how computers work. The instructions (software) are first written into RAM, and the computer executes them to input, process and output the data.RAM is a temporary workspace, while storage is permanent and comprises any hard drive, solid state drive (SSD), optical disc or USB drive on the same computer or another computer in the network. After processing the data internally, the computer can send a copy of the results from RAM back to storage, to a printer or to another computer in the network. The more RAM, the more programs and data the computer can work with quickly, and entry-level computers have at least two gigabytes of RAM. The more storage, the more data can be saved. Entry-level computers typically have at least 512GB (gigabytes) of disk storage or 128GB of SSD storage.Storage can only be read and written in large blocks called "sectors" that hold hundreds or thousands of bytes. However, it is the RAM that allows one or more bytes to be manipulated independently. This "single byte addressability" is the entire reason data are brought into RAM for processing. See RAM and storage vs. memory.Processing (The 3 C's)The computer performs all processing by "calculating," "comparing" and "copying" the data in RAM.Calculate - Compute Amounts and Keep TrackA computer can add, subtract, multiply and divide numbers to compute money amounts as well as geometric measurements of all variety. The computer's calculating capability enables it to keep track of its own internal iterations for myriad tasks.Compare - Match One Set With AnotherThe computer can look at two sets of data and determine whether they are equal or which set is higher or lower in value. Comparing is performed for searching, analyzing and evaluating data for countless purposes.Copy - From One Place to AnotherThe computer can rearrange data for organizing and reporting by copying data from one area in memory to another. In fact, in France and Spain, a computer is actually called an "organizer."

A device used for computing and otherwise processing information; specif., an electronic machine which, by means of stored instructions and information, is used to perform rapid, often complex calculations, compile and correlate data, download and play audio and video communications, access the World Wide Web, send and receive e-mail, etc.; now, esp., digital computer.

A programmable machine that responds to specified instructions and can execute a list of instructions known as a program. Today’s computers are electronic and ­digital—with wires, transistors, and circuits comprising the hardware and instructions and data comprising the software. Computers generally have these hardware components: (1) memory, allowing a computer to store data and programs, at least temporarily; (2) mass storage devices, allowing a computer to store and retain large amounts of data on the disk drives and tape drives; (3) input devices such as keyboards and a mouse, which act as conduits through which data are entered into a computer; (4) output devices, such as display screens and printers, that let users see what the computer has performed; and (5) a CPU or central processing unit, the primary component that executes the commands or instructions. On a humorous note, in a New Scientist article, futurologist Ray Kurzwell said that although a $1,000 personal computer in 2005 has about the computing power equivalent to that of an insect brain, if development advances continue at the same rate into the future, within 15 years a $1,000 personal computer should have the computing power equivalent to that of a human brain. On a global note, a controversial “computer-political” case arose on March 8, 2005, when Japan’s anti-monopoly agency demanded that Intel Corporation stop business practices that the agency alleged were giving the world’s dominant CPU chip maker an unfair advantage in the PC marketplace. Japan’s Fair Trade Commission (FTC) maintained that it would put forth a motion to enforce harsh actions if Intel failed to respond within 10 days to the allegations. In particular, the FTC claimed that Intel was in breach of Japan’s antitrust laws as early as 2002 when the company gave discounts and marketing payments to PC manufacturers in exchange for exclusivity or near-exclusivity. The FTC claimed that Intel was engaging in actions to keep the CPUs made by competing companies from being used—thus resulting in the limited marketing success of Japan’s own CPU chip manufacturers. Intel’s marketshare of the CPU market in Japan rose to 90% in 2004 from 78% in 2002. The FTC alleged that Intel had offered special incentives to Hitachi Ltd., Sony Corporation, Fujitsu Ltd., Toshiba Corporation, and NEC Corporation to use the Intel chip and the branding of “Intel Inside” or “Centrino” (Intel’s wireless networking chipset). Intel defended its business practices as being not only fair but also lawful. Associated Press. Microchips: Japanese Watchdog says Intel Practices Illegal. The Globe and Mail, March 9, 2005, p.
