a) A complete set of quantized levels containing all of the bits.

Bytes consisting of 8 to 10 bits per sample are typical.

b) Group of eight bits. Can be used to represent a character. Microcomputer instructions require one, two, or three bytes. A word can be one or more bytes.

c) A group of adjacent binary digits operated upon as a unit, capable of holding one character in the local character set, and usually shorter than a computer word (frequently connotes a group of eight bits). Current usage within the context of electronic production concerns is tending to define a byte as eight bits to have a consistent data unit for measuring memory capacities, etc.

d) 8 bits. The combination of 8 bits into 1 byte allows each byte to represent 256 possible values. See Megabyte, Gigabyte, Terabyte.

1 byte = 8 bits = 256 discrete values (brightness, color, etc.) 1 kilobyte = 1,024 bytes (not 1000 bytes) 1 megabyte = 1,048,576 bytes (not one million bytes) 1 gigabyte = 1, 073,741,824 bytes (not one billion bytes) 1 terabyte = 1,099,511,627,776 bytes (not one trillion bytes)
