which is effective parallel or serial communication?

Answer Posted / s.naveen kumar

Serial Communication no matter is high speed ex if u want to
transmit 8 bits of data serially it requires 8 clock cycles
and receiver has to wait 8 clock cycles to process the data.

So processing data will be slow.Less hardware is req.

Where as in parallel transmission all 8 bits are available
in single clock cycle so processing time is fast.More
Hardware is req to implement

The conclusion lies on transmission and processing time you
have to choose according to the application

Is This Answer Correct ?    9 Yes 1 No
