Operating System Problema

(a) Multiprogramming and period sharing strategy requires keeping some(prenominal) jobs in computer memory. First problem face by this systems ar maintaining several program in memory, like many exploiters are using different programs to lay out different processes for each user all programs should be on main memory that requires beseeming memory management. Second part is as multiple jobs rails concurrently may affect superstar another, like both 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 can fulfil same level of security in multiprogramming systems by using suitable memory management for maintaining each user program in memory as well as by CPU scheduling. To manage memory a technique is use known as virtual memory, realistic memory enable users to run programs that are larger than actual natural memory. Well CPU scheduling is another technique to lift mix-up between processes, if several jobs are ready to run at the same time system make decision to choose among them.

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



Resources guardedly manage in mainframe and minicomputers are: ? ? ? ? CPU time Memory allocation I/O Also honorable distribution of resources 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 computation mark server

Handheld Computers: Operating system involve in take hold computers carefully manages:

? ?

Individual usability Performance per unit of battery

Answer # 1.16:
a. sight programming: (Handheld device) handheld device has small memory to draw processes. Ultimately 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
