If you look at any process you’ll notice that it spends some time executing instructions (computing) and then makes some I/O request for example to read or write data to a file or to get input from a user. After that it executes more instructions and then again waits on I/O. The period of computation between I/O requests is called the CPU burst.

Interactive processes spend more time waiting for I/O and generally experience short CPU bursts
