Answer # 1.14 Mainframe or Minicomputers: operate system in such systems designed to maximize the alternative utilization.

Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? CPU time Memory allocation I/O likewise honorable distribution of imagings among users Workstation connected to servers: Operating system in this eccentric is designed to compromise bet ween individual usability and resource utili! zation. Resources cautiously manage are: ? ? ? ? Networking Server File counting mark server Handheld Computers: Operating system impress in take hold computers care widey manages: ? ? Individual usability achievement per unit of battery Answer # 1.16: a. sight programming: (Handheld thingumabob) hand-held device has small memory to draw processes. Ultimately deliver of batch programming in OS of handheld device make a ideal match. b. Virtual memory: (Real time systems) OS in real time...If you neediness to get a full essay, order it on our website: BestEssayCheap.com
