1.0 INTRODUCTION

Recent advances in micro-electronics have brought us to the age

of the inexpensive, yet powerful, microprocessor. Closely resembling

the advances of the 1960's which brought about the transition from

batch processing to time-sharing, this technological trend suggests

the birth of decentralized architectures where the processing power

is shifted closer to the user in the form of intelligent personal

workstations. The virtual terminal model described in th...
