What are the advantages of parallel transmission? What is the chief disadvantage?
What will be an ideal response?
A parallel mode of transmission has two chief advantages:
? High speed: Because it can send N bits at the same time, a parallel interface can operate N
times faster than an equivalent serial interface.
? Match to underlying hardware: Internally, computer and communication hardware uses
parallel circuitry. Thus, a parallel interface matches the internal hardware well.
The main disadvantage of parallel transmission is number of cables required, for long distance
communication, this is an important consideration.
