CPU burst VS I/O burst

CPU burst VS I/O burst

Process somethimes use CPU burst, sometimes use I/O burst.
CPU burst means Process operates CPU commands.
I/O burst is a waiting time for input or output through device.

CPU-burst If CPU burst time is 10sec, CPU completes the Process for 10sec.
I/O burst coming after CPU burst means the process needs input or output
to operate the next CPU burst.

Process burst has 2 types: CPU bound process and I/O bound process.

If the Process has more CPU burst than I/O burst, it is CPU bound process.
If the Process has more I/O burst than CPU burst, it is I/O bound process.

CPU-burst In CPU burst, Users do not attempt the Process, which means that the process
work only (e.g. scientific calculator). CPU bound Process time is usually short.
