Difference between synchronous & asynchronous communication.

Answer Posted / arjesh kumar

In synch transmission,the two units share a common clock
frequency and bits are transmitted continuously at the rate
dicted by the clock pulse. in long distant seriel
transmission , each unit is driven by aseparate clock of
the same requency. synchronisation signals are transmitted
periodically b/w the two units to keep there clocks in step
with each other.
A serial asynchronous data transmission technique used in
many interactive terminals employs special bits that are
inserted at both ends of the character code. with this
tchnique , each character cosists of three parts ;a start
bit , the character bit, and stop bits.
