In which transmission there is only one line and bits are sent sequentially.
In Serial transmission there is only one line and bits are sent sequentially.
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. ... Parallel data transmission sends multiple data bits at the same time over multiple channels.
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 .
Serial transmission is where bits are transmitted one at a time over a single channel, particularly used within USB devices. Parallel transmission is where bits are sent simultaneously over their own individual channel.
