A word processor (WP) [1] [2] is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features.. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.
Word processing became the most popular use for personal computers, and unlike the spreadsheet (dominated by Lotus 1-2-3) and database markets, WordPerfect, XyWrite, Microsoft Word, pfs:Write, and dozens of other word processing software brands competed in the 1980s; PC Magazine reviewed 57 different programs in one January 1986 issue.

A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits [a] in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architecture.
A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations.
A word processor program is an application program that provides word processing functions. The most basic of them include input, editing, formatting, and output of rich text . The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).

The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch–execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.
