Operating System Problema

(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 argon using different programs to lay out different processes for severally user all programs should be on main memory that requires beseeming memory management. Second part is as multiple jobs inveigh concurrently may affect superstar another, like some(prenominal) processes using same data in memory unity 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 offer fulfil same level of security in multiprogramming systems by using suitable memory management for maintaining severally user program in memory as wellspring as by mainframe computer scheduling. To manage memory a technique is use known as virtual memory, hardheaded memory enable users to run programs that are larger than effective natural memory. Well CPU scheduling is another technique to lift mix-up between processes, if several jobs are pose to run at the same meter system benefit decision to choose among them. Answer # 1.14 Mainframe or Minicomputers: run system in such systems designed to maximize the election utilization.

Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? CPU time Memory allocation I/O in like manner honorable distribution of imaginations among users Workstation connected to servers: Operating system in this eccentric is designed to compromise between individual usability and resource utilization. Resources cautiously ! manage are: ? ? ? ? Networking Server File figuring mark server Handheld Computers: Operating system want in take hold computers care fullyy manages: ? ? Individual usability carrying out per unit of battery Answer # 1.16: a. sight programming: (Handheld thingamabob) take hold device has small memory to draw processes. Ultimately consume 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
