Synchronous

Synchronous is a term which means that some event, or device, operates on a clock, or with fixed timing.

A synchronous serial line uses a fixed clock (which is usually provided by one end, or by the transmission channel itself) which is carried on a separate signal line.

Contemporary logic design is usually synchronous; a clock signal is used to control when flip-flops are clocked, etc.
