word

In computing, a group of bits (binary digits) that a computer's central processing unit treats as a single working unit. The size of a word varies from one computer to another and, in general, increasing the word length leads to a faster and more powerful computer. In the late 1970s and early 1980s, most microcomputers were 8-bit machines. During the 1980s 16-bit microcomputers were introduced and 32-bit microcomputers are now available. Mainframe computers may be 32-bit or 64-bit machines.

Word

In computing, versatile and powerful word-processing program developed by Microsoft for IBM-compatible and Apple Macintosh PCs. The program began its life as a MS-DOS program in 1983, and a year later it was released as one of the first programs for the Macintosh. The advanced features and ease of use of Version 6.0, released in 1994, established Word as the market leader in its field. A series of enhancements and further versions followed.
