byte
A '''byte''' is a group of 8 bits. As a bit is one binary digit, a byte can be used to represent any number from 0 to 255.A byte is the basic unit for data storage and manipulation, as well as measuring information-handling capacity.
One half of a byte (4 bits) is called a '''nibble'''.
A byte can also be called a word, two bytes can also be called a dword and four can be called a qword. I also think that eight bytes is called a uword, but I'm not sure.
For larger quantities of bytes, we use the metric system prefixes for sizing, with one notable exception: due to the binary nature of bytes, we do not separate them exactly into groups of 1000, as the metric system would normally suggest. Instead, we use a factor of 1024 to scale the measurements. Thus:
1 kilobyte (KB) = 1,024 bytes 1 megabyte (MB) = 1,024 kilobytes = 1,048,576 bytes 1 gigabyte (GB) = 1,024 megabytes = 1,073,741,824 bytes 1 terabyte (TB) = 1,024 gigabytes = 1,099,511,627,776 bytes 1 petabyte (PB) = 1,024 terabytes = 1,125,899,906,842,624 bytes
