Parallel Communication

Parallel communication sends multiple bits in parallel (through multiple buses). This is hard because you need to Synchronization across mu

in Serial Communication you can just spit it out.

Examples of parallel communication systems:

• Internal buses: memory bus, system bus, and front-side bus

• Multiple Serial Buses: Imagine you have four serial buses, each sending one bit at a time. While you might be sending four bits at once across the system (because of four buses), each bus is still sending data serially, so the communication is not parallel by definition.

• Parallel Communication: In parallel communication, you would have four wires, and each wire would carry one bit of a four-bit value at the same time (synchronized), which makes it parallel.
