... known as the baud rate. Generally, one baud is one bit per second. There is no simple relationship between the baud rate and rate of data transfer between devices because additional "framing" bits have to be transmitted with each character to provide start/stops bits, error detection and other communications controls. A baud rate of 56K is therefore not necessarily 7000 characters per second. (8 bits in a byte 56 ÷ 8 = 7 7 × 1000) Parity Computers use either odd or even parity. In an even parity machine, the total number of 'on' bits in every byte must be an even number. When data is transmitted, the parity bits are checked at both the sending and receiving end and if they are different, or the number of parity bits 'on' is wrong, an error message is displayed. In the diagram below the parity bit is the most significant bit (MSB). Synchronous ...
