 # Multitasking
 To speed up computers we overlap CPU time and IO Time.

+While a program waits for IO, other programs can use CPU. This solution requires multiple programs to be loaded into memory, hence the name multitasking.
+
+Multitasking overlaps IO time of a program with CPU time of other program.
+
+## Multitasking with multiple processors
+If computer has a single CPU, programs should take turns in using it.
+
+If computer has multiple CPUS, each task can be given a different CPU.
+	- If the number of tasks is more than available cpu's, we still take turns.

+when program issues IO command, cpu is granted to the next program.
