In a multiprogramming environment :

a single user can execute many programs at the same time

the processor executes more than one process at a time

the programs are developed by more than one person

more than one process resides in the memory

a single user can execute many programs at the same time

The primary distinction between the short term scheduler and the long term scheduler is :

The type of processes they schedule

The frequency of their execution

What is a short-term scheduler ?

It selects which process to remove from memory by swapping

It selects which process has to be brought into the ready queue

It selects which process has to be executed next and allocates CPU

It selects which process to remove from memory by swapping

What is a medium-term scheduler ?

It selects which process has to be brought into the ready queue

It selects which process has to be executed next and allocates CPU

It selects which process to remove from memory by swapping

What is a long-term scheduler ?

It selects which process has to be executed next and allocates CPU

It selects which process has to be brought into the ready queue

It selects which process has to be executed next and allocates CPU

It selects which process to remove from memory by swapping

When a process terminates :

It is removed from all, but the job queue

Its process control block is de-allocated

Its process control block is never de-allocated

When the process issues an I/O request :

It is placed in a waiting queue

It is placed in the ready queue

The objective of multiprogramming is to :

Have multiple programs waiting in a queue ready to run

Have some process running at all times

Have multiple programs waiting in a queue ready to run

The degree of multiprogramming is:

the number of processes executed per unit time

the number of processes in the ready queue

the number of processes in the I/O queue

the number of processes in memory

The state of a process is defined by:

the final activity of the process

the activity just executed by the process

the activity to next be executed by the process

the current activity of the process

A set of processes is deadlock if

each process is blocked and will remain so forever

all processes are trying to kill each other

What is interprocess communication?

communication between two threads of same process

communication within the process

communication between two process

communication between two threads of same process

What is the ready state of a process?

when process is unable to run until some task has been completed

when process is scheduled to run after some execution

when process is unable to run until some task has been completed

In operating system, each process has its own

address space and global variables

pending alarms, signals and signal handlers

By operating system, the resource management can be done via

both time and space division multiplexing

The main function of the command interpreter is

to provide the interface between the API and application program

to get and execute the next user-specified command

to provide the interface between the API and application program

to handle the files in operating system

Which one of the following error will be handle by the operating system?

connection failure in the network

Which one of the following is not true?

kernel remains in the memory during the entire computer session

kernel is the program that constitutes the central core of the operating system

kernel is the first part of operating system to load into memory during booting

kernel is made of various modules which can not be loaded in running operating system

kernel remains in the memory during the entire computer session
