Serial communication and parallel communication differences! (2009-05-07 19:40:17) there are multiple data bits in parallel communication transport, and transmission between two devices. The sending device transmits these data bits to the receiving device via the corresponding data line, plus a data check digit. The receiving device can receive the data at the same time without any transformation to use directly. The parallel mode is mainly used for near-distance communication. The bus structure in the computer is an example of parallel communication. The advantage of this approach is that the transmission is fast and simple. Serial data transmission, data is a bit a ground in the line of communication transmission, first by computing machines with several bus to send equipment, transform and several parallel data via - string hardware converts serial mode, and bit by bit by the transmission line to reach the terminal device, and at the receiving end converts data from serial to parallel way, to be used by the receiving party. Serial data transfers are much slower than parallel transports, but they are more realistic for the very wide range of public telephone systems. There are three kinds of directional structure of serial data communication, namely, single, half duplex, and full duplex. one The difference between parallel and serial transmission transmission From the perspective of the situation of technology development, serial transmission mode is replaced by the momentum of parallel transmission mode, USB instead of IEEE 1284, SATA replace PATA, PCI Express replace PCI... In principle, parallel transport is better than serial transmission. In plain English, the parallel transmission ro
