Serial Communication (Simplex)

Defination

In telecommunication and computer science, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.

Types Of Serial Communication:

1. Synchronous
2. Asynchronous (Discuss In This Post)

Modes Of Communication
