Some questions could have multiple correct answers Choose all correct answers - a point for each correct answer selected a hall-point off for each incorrect answer selected QUESTION Which computer features were introduced to facilitate batch processing? DA. privileged instructions OB. virtual memory oc. pipelining OD. & job control language CH QUESTION Multiprogramming was added to a batch computer system OA. to maximize processor utilization. OB. to minimize user response time. QUESTIONS What are the goal(s) of multitasking in a timesharing system? CA. maximize processor utilization OB. minimize response time oc. allow one user to share multiple programs OD. allow multiple users to share processor and hardware time QUESTION To implement multiprogrammed batch processing, hardware should support OB. I/O interrupts Bc. privileged Instructions OD. multi-threaded processors QUESTIONS The kernel of a monolithic operating system CA. remains in main memory at all times during system operation. DB. is executed in a protected area of memory. Oc. must be able to suspend and resume execution of itselt. OD. can be removed from memory to make room for user programs. QUESTIONS For an operating system to evolve, it should DA. be modular in design, allowing for greater flexibility and change. OD. change as hardware architecture changes. oc. be able to support a new hardware device added to the system. OD. distribute patches to fix problems. QUESTION 7 Duties of an operating system include DA. providing an interface for end-users. OB. implementing cache memory and DMA. oc. allocating resources and scheduling jobs. OD. providing error detection and response. QUESTION As an example of a monolithie kernel, the Linux kernel CA. runs on special kernel circuits - user programs run on user circuits. OB. is a single process that executes in kernel mode. DC. supports multitasking and multithreading. OD. disables (not blocks hardware interrupts while executing kernel code. Com QUESTIOND What problems served to develop the concept of the process? DA. Scheduling in multiprogramming batch operating systems OB. scheduling in time share systems DC. synchronization in multiuser real time transaction systems OD. All of the above QUESTION 10 A paging memory management system provides dynamic mapping between a virtual address in a program and OA. a virtual address in physical memory. B. a real address in physical memory. oc. a real address in a program. OD. another virtual address
