Which transmission suits long distances?
Short answer. Serial, because it needs only one line and signals do not clash.
Where is parallel transmission used?
On short paths, like the connections inside a computer.
Serial vs parallel
| Point | Serial | Parallel |
|---|---|---|
| Bits | One by one | Many at once |
| Distance | Long | Short |
| Cost | Low | High |
Remember
| Serial: a single queue |
| Parallel: side by side |
Do bits travel in a queue or side by side? Serial sends one bit at a time. It suits long distances. Parallel sends many at once. It is costly, so it stays short. Remember. Serial is a queue. Parallel is side by side.
