Most people using a personal computer work according to a cyclical pattern. A program developer for instance will repeatedly execute and load the functions EDIT, COMPILE and EXECUTE from secondary storage. The efficiency of this user-cycle critically depends on the performance of the channel to secondary storage. However, if all programs required during one user cycle can be kept in local main memory then the local disk can be omitted and even a medium speed local area network will be adequate to supply the missing portions of data and code.
