What is serial communication?
In order to understand communication protocols we first need to understand digital systems. A digital systems communicates a message in the form of binary information. This is a flow of digital pulses sent from one point to another creating a means of data transmission. Serial communication is a widely used medium to transfer information between various different equipment and peripherals. Data is in the form of sequential binary pulses. Binary can be represented in two states i.e: a one (1) represents a logic high or "on" status and a zero (0) represents a logic low or "off" status. The different modes of transmitting data over serial communication Simplex transmission is a one-way communications method, with only one client present on the network. if a sender engages in transmission then a receiver is only able to accept information. examples: Radio and television transmission. Half Duplex mode have both an active sender and a receiver, ho
