Fanontaniana matetika: Inona ny disk IO amin'ny Linux?

Disk I/O is input/output (write/read) operations on a physical disk (or other storage). Requests which involve disk I/O can be slowed greatly if CPUs need to wait on the disk to read or write data. I/O Wait, (more about that below) is the percentage of time the CPU has to wait on disk.

What is disk IO?
