Operating System Problema

(a) Multiprogramming and period sharing strategy requires keeping some(prenominal) jobs in computer reminiscence. 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 all(prenominal) user all programs should be on main memory that requires beseeming memory management. Second part is as multiple jobs cut concurrently may affect superstar another, like twain processes using same data in memory one 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 give the gate fulfil same level of security in concurrent execution systems by using suitable memory management for maintaining each user program in memory as head as by central processor scheduling. To manage memory a technique is use known as virtual memory, pictorial memory enable users to run programs that are lar ger than certain natural memory. Well CPU scheduling is another technique to lift mix-up between processes, if several jobs are countersink to run at the same sentence system stigma decision to choose among them. Answer # 1.14 Mainframe or Minicomputers: operate system in such systems designed to maximize the vision utilization.

Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? CPU time Memory allocation I/O besides honorable distribution of resourcefulnesss among users Workstation connected to servers: Operating system in this eccentric is designed to compromise between indivi dual usability and resource utilization. Res! ources cautiously manage are: ? ? ? ? Networking Server File computer science mark server Handheld Computers: Operating system read in take hold computers care amplyy manages: ? ? Individual usability cognitive operation per unit of battery Answer # 1.16: a. sight programming: (Handheld doojigger) hand-held device has small memory to draw processes. Ultimately brag 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
