Abstract

The characteristic of third generation computing systems that most distinguishes them from previous ones is that they are designed to perform multiprogramming. The purpose of multiprogramming is cost-effective utilization of computer hardware, which is achieved by reducing the CPU time otherwise lost waiting for completion of I/O or operator action. An operating system is necessary to achieve multiprogramming: to schedule jobs, allocate resources, and perform services such as I/O.
