CPU Bound jobs are jobs that spend most of their time using the CPU, although they do preform I/O operations as well.

I/O Bound jobs are jobs that spend most of their time doing I/O, although they do use the CPU as well.

When a process is cpu-bound it is limited by the available cpu cycles.

When i/o/ bound it is limited by the speed of disk i/o

In either case, if you add resource: - more cpu or faster disk access -- the program speeds up.
