What is computer? – Definition from WhatIs.com

A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program, software, or sequence of instructions on how the data is to be processed.

Complex computers include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer hardware (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today’s computers have both kinds of programming.

Major types of computers

Analog computer – represents data by measurable quantities
Desktop computer – a personal computer that fits on a desk and is often used for business or gaming
Digital computer – operates with numbers expressed as digits
Hybrid computer –

What is system software? – Definition from WhatIs.com

System software is a type of computer program that is designed to run a computer’s hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. The operating system (OS) is the best-known example of system software. The OS manages all the other programs in a computer.

Other examples of system software include:

  • The BIOS (basic input/output system) gets the computer system started after you turn it on and manages the data flow between the operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
  • The boot program loads the operating system into the computer’s main memory or random access memory (RAM).
  • An assembler takes basic computer instructions and converts them into a pattern of bits that the computer’s processor can use to perform its basic operations.
  • A

What is Web site? – Definition from WhatIs.com

This definition is also listed under presence, site and Website.

A Web site is a related collection of World Wide Web (WWW) files that includes a beginning file called a home page. A company or an individual tells you how to get to their Web site by giving you the address of their home page. From the home page, you can get to all the other pages on their site. For example, the Web site for IBM has the home page address of http://www.ibm.com. (The home page address actually includes a specific file name like index.html but, as in IBM’s case, when a standard default name is set up, users don’t have to enter the file name.) IBM’s home page address leads to thousands of pages. (But a Web site can also be just a few pages.)

Since site implies a geographic place, a Web site can be

What is software? – Definition from WhatIs.com

Software is a set of instructions, data or programs used to operate computers and execute specific tasks. Opposite of hardware, which describes the physical aspects of a computer, software is a generic term used to refer to applications, scripts and programs that run on a device. Software can be thought of as the variable part of a computer and hardware the invariable part.

Software is often divided into application software, or user downloaded programs that fulfill a want or need, and system software, which includes operating systems and any program that supports application software. The term middleware is sometimes used to describe programming that mediates between application and system software or between two different kinds of application software. For example, middleware could be used to send a remote work request from an application in a computer that has one kind of operating system to an application in a computer with
