Really bad explanation by the parent!
The clock, in the case of computing, can be considered akin to a metrognome in music.
Each process takes a finite number of "ticks" of the system clock.
A synchronus system means that ALL processes within the system are timed by the same physical clock, meaning that they are all basically synchronized!
An asynchronus system means that different parts of the system run off different clocks, which may run at different frequencies (well, they will always run at slightly different frequencies" or different phases, which simplistically means that we have to store data in a buffer until the "reading" clock catches up with the "writing" clock...
