In which transmission bits are send one after another without start/stop bits or gaps.
In Synchronous transmission bits are send one after another without start/stop bits or gaps.
Parallel devices have a wider data bus than serial devices and can therefore transfer data in words of one or more bytes at a time. As a result, there is a speedup in parallel transmission bit rate over serial transmission bit rate.
Data is transferred in the form of bits between two or more digital devices. There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel.
Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted via parallel mode on buses with the width of the parallel bus matched to the word size of the computer system. Data between computer systems is usually transmitted in bit serial mode .
In Synchronous data transfer, data is transmitted in the form of blocks or frames whereas in asynchronous data transfer, transmission is done in 1 byte or character at a time. ... Synchronous Communication: It is based on synchronization between the sender and the receiver.
