a. Wide use of computer networks and the increasing use of single-user workstations
A computer network is a collection of connected computing devices that share resources, data, and information. Computers, servers, routers, switches, printers, and other peripherals are examples of such devices.
The widespread use of computer networks and the increasing use of single-user workstations is not a significant feature of fifth generation computers because they were already common in the fourth generation.
Fifth-generation computers are notable for their use of advanced parallel processing technologies, artificial intelligence, natural language processing, expert systems, and high-level programming languages.
Furthermore, fifth-generation computers are built with advanced user interfaces and multimedia applications in mind.
