Byte Per Second (B/s)

ComputingCurrent unit

Eight bits per second.

1 byte per second = 8 bits per second (exactly).

1 byte per second = 8 bits per second

About the byte per second

Byte is a younger word than bit. Werner Buchholz coined it in June 1956 during the early design of the IBM Stretch computer, deliberately spelling it with a y so that nobody would mistake it for bit. At first it had no fixed size, and Stretch's early design allowed groups of one to six bits. Eight-bit bytes were then built into Stretch, and IBM's System/360 spread them widely in the 1960s. Another person, Louis Dooley, has also claimed to have coined the term at MIT Lincoln Laboratory around 1956 or 1957.

A byte per second is eight bits per second, the smallest rate counted in bytes. Protocol documents that need to avoid any ambiguity often use the word octet for exactly eight bits. The unit is tiny by modern standards. On serial links, start, stop and parity bits mean the line must run at a higher bit rate than the byte rate alone suggests.
