Assignment Overview
The transmission of a data stream from one device to another requires cooperation from all transmitting sites through synchronization. In asynchronous transmissions, each character of data is treated independently, and each byte begins with a start bit for the receiving end to know that a character is arriving; however, sending data in one block is more efficient than sending one character at the time. Each block of data is formatted as a frame. A form of synchronization such as the Manchester encoding is used. It is possible for errors to occur in transmission, and for this reason, the HDLC protocol creates a layer of control. Circuit switching is used in public telephone networks but is also used for dedicated lines to establish the path between two stations. Packet switching is an efficient way in the design of share facilities in a communication network.
