- common unit of computer storage
- 8 binary digits (bits) = 1 byte
- smallest addressable group of bits accessible by computer
- a byte holds the equivalent of a single character
- allows computers to talk to each other
- 128 characters, 33 non printing controls that effect text and space
- used to control printers
-allows the import and export of data
tab delimited
ASCII, way info separated
