Question

definition of computer?

Answer 1

1. A device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.
2. One who computes.

Computer:
A device that receives, processes, and presents information. The two basic types of computers are analog and digital. Although generally not regarded as such, the most prevalent computer is the simple mechanical analog computer, in which gears, levers, ratchets, and pawls perform mathematical operations—for example, the speedometer and the watt-hour meter (used to measure accumulated electrical usage). The general public has become much more aware of the digital computer with the rapid proliferation of the hand-held calculator and a large variety of intelligent devices and especially with exposure to the Internet and the World Wide Web.

An analog computer uses inputs that are proportional to the instantaneous value of variable quantities, combines these inputs in a predetermined way, and produces outputs that are a continuously varying function of the inputs and the processing. These outputs are then displayed or connected to another device to cause action, as in the case of a speed governor or other control device. Small electronic analog computers are frequently used as components in control systems. If the analog computer is built solely for one purpose, it is termed a special-purpose electronic analog computer. In any analog computer the key concepts involve special versus general-purpose computer designs, and the technology utilized to construct the computer itself, mechanical or electronic.

In contrast, a digital computer uses symbolic representations of its variables. The arithmetic unit is constructed to follow the rules of one (or more) number systems. Further, the digital computer uses individual discrete states to represent the digits of the number system chosen. A digital computer can easily store and manipulate numbers, letters, images, sounds, or graphical information represented by a symbolic code. Through the use of the stored program, the digital computer achieves a degree of flexibility unequaled by any other computing or data-processing device.

The advent of the relatively inexpensive and readily available personal computer, and the combination of the computer and communications, such as by the use of networks, have dramatically expanded computer applications. The most common application now is probably text and word processing, followed by electronic mail.

Computers have begun to meet the barrier imposed by the speed of light in achieving higher speeds. This has led to research and development in the areas of parallel computers (in order to accomplish more in parallel rather than by serial computation) and distributed computers (taking advantage of network connections to spread the work around, thus achieving more parallelism). Continuing demand for more processing power has led to significant changes in computer hardware and software architectures, both to increase the speed of basic operations and to reduce the overall processing time.

Answer 2

A pc may be a machine that manipulates information per an inventory of directions.

Computers take various physical forms. the primary devices that check fashionable computers date to the mid-20th century (around 1940 - 1945), though the pc construct and varied machines almost like computers existed earlier. Early electronic computers were the scale of an oversized area, intense the maximum amount power as many hundred fashionable personal computers.[1] fashionable computers ar supported relatively little integrated circuits and ar millions to billions of times a lot of capable whereas occupying a fraction of the area.[2] Today, easy computers is also created sufficiently little to suit into a watch and be battery-powered from a watch battery. Personal computers in varied forms ar icons of the knowledge Age and ar what most of the people consider as "a computer"; but, the foremost common style of pc in use these days is that the embedded pc. Embedded computers ar little, easy devices that wont to management alternative devices—for example, they'll be found in machines starting from airplane to industrial robots, digital cameras, and children's toys.

The ability to store and execute lists of directions known as programs makes computers very versatile and distinguishes them from calculators. The Church–Turing thesis may be a statement of this versatility: any pc with an exact minimum capability is, in essence, capable of playing identical tasks that the other pc will perform. Therefore, computers with capability and quality starting from that of a private digital assistant to a mainframe computer ar all able to perform identical process tasks given enough time and storage capability.

Answer 3

The proper term for a computer is an inventions that converts information digitally and allows someone to have entertainment purposes for the use of this these are complex inventions with the guides of proper use by someone that knows how to illustrate to use one properly. Nah thats my term for it, the term for a computer can be multiple and expressed in different ways but mainly the best term to express for a computer is something you should use from the web as I can't be assed making a backside of myself to explain it properly... or making the wrong explanation..

Answer 4

A computer is an electronic device that takes instruction from the user and provides these instructions to the hardware and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed.
