Description: Parallel and serial communication is communication between the CPU and the external equipment to carry out the basic method of information exchange. Parallel communication to form a character or data you send, every occupier of a communication line, also need to contact to ensure coordination and peripherals to work, it has a higher transmission speed. However, due to the long-term drive and receive the signal more difficult to drive and receive circuits more complex, so the transmission distance parallel communication is limited, this means of communication used for the computer itself, or as a close-up computer and peripheral equipment used to transmit information.
