PPSC Lecturer Computer Science Quiz no 11 A.J. Bhatti September 10, 2020 Welcome to your PPSC Lecturer Computer Science Quiz no 11 Name Email Each process is represented in the operating system by a process control block (PCB) – also called a Process control Board Task Control Board PCB TCUB All of the Above Process state: The state may be new, ready, running, waiting, halted and so on .........TRUE or FALSE Yes True No False ALl of the above None of the above The counter indicates the address of the next instruction to be executed for this process Process State Program Counter CPU Register CPU Scheduling information Micro kernels typically provide minimum process and ............. management in addition to a communication facility memory management Project management Process Management All of the above This information may include such information such as the value of the base and limit registers, the page tables, or the segment tables, depending on the memory system used by the operating system. Memory-management information CPU-management information Memory-Scheduling information CPU-Scheduling information This information includes a process priority, pointers to scheduling queues, and any other scheduling parameters CPU Scheduling CPU Scheduling information CPU Scheduling Process CPU Scheduling Project This information includes the amount of CPU and real time used, time limits, account numbers, job or process numbers, and so on is known as CPU Accounting information Accounting information Memory Accounting information Memory Information The information includes the list of I/O devices allocated to the process, a list of open files, and so on is known as CPU Process information Memory Process Information Monitor Process Information I/O status information The objective of multiprogramming is to have some process running all the time so as to ....................... maximize CPU utilization minimize CPU utilization maintain CPU utilization All of the above Switching the CPU from one process to another requires saving of the context of the current process and loading the state of the new process,This is called content switching context switching contact switching Process switching As processes enter the system, they are put into a job queue. This queue consists of all processes in the .......... CPU Monitor Scheduling system The processes that are residing in main memory and are ready and waiting to execute are kept on a list called the ........... Job queue ready queue Process queue All of these When a process is allocated the CPU, it executes for a while, and eventually quits, is interrupted or waits for a particular event, such as completion of an I/O request. In the case of an I/O request, the device may be busy with the I/O request of some other process, hence the list of processes waiting for a particular I/O device is called a ............ Process Queue Job Queue device queue Both A & B A process migrates between the various scheduling queues throughout its .......... Progressing lifetime CPU Time All of Them In .............scheduler (or job scheduler) selects which processes should be brought into the ready queue, from the job pool that is the list of all jobs in the system Long Term Short Term Middle Level None of the above The ................ scheduler (or CPU scheduler) selects which process should be executed next and allocates CPU. Short-term Long-term Middle-term All of the above At some later time the process can be reintroduced at some later stage, this scheme is called ......... Processing Progressing swapping Sneeking The area on the disk where swapped out processes are stored is called the ........... swap space Process space Progress Space All of Above A process may create several ................. via a create-process system call during the course of its execution new processes old processes previous processes short processes The creating process is called a parent process while the new processes are called the ............ of that process children Father children parent Parent Childern The ............ call suspends the calling process until one of the immediate children terminate, or until a child that is being trainterestced stops because it has hit an event of wait system wait system call not wait system Both a and b How to Cut selected item in computer .... ctrl+x ctrl+v ctrl+r ctrl+s Dynamite invented by...x Alfred Nobel Einstein edison all of them, 1 kilo byte= 1020 bytes 1000 bytes 1024 bytes 1200 bytes Indus treaty signed during era of Ayub Khan Yahya Khan Pervaiz Musharraf All of them Related Author: A.J.
