(a) Multiprogramming and period sharing strategy requires keeping some(prenominal) jobs in computer storehouse. First problem face by this systems ar maintaining several program in memory, like many exploiters ar using different programs to lay out different processes for each(prenominal) user all programs should be on main memory that requires beseeming memory management. Second part is as multiple jobs caterpillar track concurrently may affect superstar another, like both processes using same data in memory unrivaled is modifying it and second one is reading same data. In this scenario in that location will be always possibility of malfunctioning. (b) Yes we clear fulfil same level of security in concurrent execution systems by using suitable memory management for maintaining each user program in memory as sound as by processor scheduling. To manage memory a proficiency is use known as virtual memory, lifelike memory enable users to run programs that are l arger than unquestionable natural memory. Well CPU scheduling is another technique to lift mix-up between processes, if several jobs are stimulate to run at the same time system desexualise decision to choose among them. Answer # 1.14 Mainframe or Minicomputers: operating(a) system in such systems designed to maximize the imagination utilization.
Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? CPU time Memory allocation I/O withal honorable distribution of imaginativenesss among users Workstation connected to servers: Operating system in this eccentric is designed to compromise between individual usability and resource utilizati! on. Resources cautiously manage are: ? ? ? ? Networking Server File counting mark server Handheld Computers: Operating system move in take hold computers care dependabley manages: ? ? Individual usability transaction per unit of battery Answer # 1.16: a. sight programming: (Handheld turn of events) handheld device has small memory to draw processes. Ultimately sustain 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: OrderCustomPaper.com
