You will learn the basic terminology of computers and how all of the equipment works together. In order to explain difficulties you experience with your computer, knowing specific information about both types of hardware will prove beneficial. There are, however, some basic concepts and terms common to both. The first term is a byte which represents a single unit of data. A byte by itself is small and pretty useless.
Computers are electronic devices that deal in pulses of electricity.
All data is reduced by the computer into a series of digits that turn ON and OFF electrical circuits. Each letter in your word processing document, and each number in your spreadsheet is reduced to a combination of 1s and 0s. Bits are combined into units called bytes . Even a space, punctuation mark, or a function command is represented by bits and bytes and take up storage on the computer. We measure a computers size and power in terms of the number of byes it can store in memory or on its hard disk.
