From the Paper:

"Modern personal computers are multi-user, multitasking systems. A user is no longer forced to wait for a given process to complete before attempting to start the next process. With the introduction of time slicing, the Central Processing Unit (CPU) of the computer can have its time divided up and shared between numbers of different processes. However the concept of multitasking brings with it the problems associated with managing the computer's memory. The operating system, in the case of this report, Microsoft Windows NT has the responsibility of distributing the available memory between applications or processes effectively, as well a number of other functions."
