The difference is that serial transmissions only use 2 wires
for transmitting and receiving data, and only 1 for sending
or receiving, and can only send one bit at a time.

Parallel cables use several wires for data transmission and
is much faster than serial thus 8 or more wires are carrying
data *parallel* to each other to it's destination.

In Serial Transmission, Data goes out one by one bit basis
at a time.
Ex - 1 0 1 0 1 1 0 1 0 1 0 > out

In Parallal Transmission, Data goes out group of bits
(Basically 1 byte) basis at a time.
Ex -
1 > out
0 > out
0 > out
1 > out
0 > out
1 > out
0 > out
1 > out


Hope u can understand little from this topic.

Mark it & let me knw the feedback.
