lecture 2: Communication Concepts
Parallel:
In parallel transmission all bits in a single character are transmitted simultaneously.
Data travels in parallel (simultaneously) within a PC over the data bus (bundle of data lines).
Similarly we can transmit data between two PCs in parallel.
That is all data lines (normally 8) from one PC are connected to the other PC.
Parallel transmission is primarily limited to transmission of data within a computer, between
computers and between a computer and a printer.
It is fast compared to serial transmission but limited to shorter distances. ...
