Operating System Problema

(a) Multi schedule and period sacramental manduction strategy requires keeping some(prenominal) jobs in computer shop. First line of work face by this systems ar maintaining several program in retention, like many exploiters be using different programs to get down out different processes for each(prenominal) user all programs should be on main memory that requires beseeming memory management. Second get is as multiple jobs cartroad concurrently may incite superstar another, like some(prenominal) processes using uniform information in memory angiotensin converting enzyme is modifying it and second one is variation same data. In this scenario in that location will be always possibility of malfunctioning. (b) Yes we force out fulfil same level of security in concurrent execution systems by using competent memory management for maintaining each user program in memory as healthful as by mainframe scheduling. To manage memory a technique is use cognize as virtual memory, real memory enable users to reach programs that be larger than tangible natural memory. Well central processing building block scheduling is another technique to lift mix-up between processes, if several jobs are define to run at the same time system shit decision to choose among them. resolving power # 1.14 Mainframe or Minicomputers: run system in such systems designed to maximize the preference utilization.

Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? mainframe computer time Memory allocation I/O too honorable distribution of imagings among users Workstation connected to servers: operating(a) system in this eccentric is designed to via media between individual usability and resource utilization. Resources cautiously manage are: ? ? ? ? Networking Server File reckoning mark server Handheld Computers: Operating system involve in take hold computers guardedly manages: ? ? Individual usability Performance per unit of battery Answer # 1.16: a. sight program: (Handheld device) hold device has humble memory to draw processes. in conclusion feature 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
