In parallel communication data is transfered parallely
ex:1
0
0
1
in parallel communication each bit requires separate path
that means for example when we transfer data from source to
destination in single wire but in parallel communication
each bit require separate wire.so cost is very high

In serial communication data is transfered serialy
ex: 0 1 1 0 1
it requires single wire to transmit all the data.
