Semaphores

The entity we create for the O/S to handle a process is a :

Struct

Table

Vector

Device

A miss indicates that the word that was referenced:

Is on the disk

Is not in cache

Is not on the stack

Is in the register

Virtual memory is a portion of the:

Registers

Main memory

Disk

Cache memory

When a process is busy waiting it is:

Waiting in the ready queue

Waiting in the device queue

Exicuting in a continous loop

Exicuting a wait(s) function

Data is transferred from memory to cache in units of

Blocks

Words

Threads

Vectors

In a multithreaded process model, each of the individual threads:

Have their own PC register

Have their own open files

Have their own stack section

Have their own data section

If the time quantum is made larger, the number of context switches will likely

Increase

Decrease

Either increase or decrease

Not be affected

A monitor used in an O/S is a

Terminal

Software module

Hardware device

Boolean flag

You delete a file from the disl. What happens to the bit sequence that was there?

It was removed by the O/S

It was erased when you clicked 'delete'

It gets changed to all zeros

Nothing

The Program Counter of a process holds a:

Process number

Memory address

Logical address

Cache address

The critical section, is a segment of code

That is needed to do critical calculations

In which a process utilizes some shared resources

In the users program that is the most important

Used in special applications which deal with life/death matters

A user process can request the services of the O/S through

Aging

Short term scheduler

System calls

Interrupts

In a multithreaded process controlled in the user level (Choose all that are true)

When any thread blocks, its process cannot continue to run

When a process blocks, its threads can continue to run

The difference between FCFS and RR in scheduling is:

Length of queue

Preemption based on a clock

Priority scheduling

None of the above

An interrupt is issued by:

The short term scheduler

The running process

The interrupt vector

The I/O device

Process B exits and there are still threads of that pocess running, they will

Continue to run untill they complete

Be put on a device queue

Be put into virtual memory

Terminate when the process exits

When a process exicutes a signal operation on a semaphore then:

The process must block itself

The process must exicute a wait(s)

The process must go to the ready queue

None of the above

A semaphore used to impliment mutual exclusion that contains a negative value indicates:

The number of resources of that type availible

The number of process using that resource that are running concurrently

Number of processes needing that resource that are blocked

Priority of the running processes that need that resource

Priority of the running processes that needs that resource

Priority of the blocked process that needs that resource

A semaphore used to impliment mutual exclusion that contains a positive value indicates:

The number of resources of that type availible

The number of process using that resource that are running concurrently

Number of processes needing that resource that are blocked

Priority of the running processes that need that resource

Priority of the running processes that needs that resource

Priority of the blocked process that needs that resource

Device drivers are

Hardware chips in the computer

Hardware chips in the device

True

False

True

False

The return address of a function call is normally held in the

Pcb structure

Return register

Stack

Cache memory

True

False

The part of the O/S that allocates memory space to a new process is the

Dispatcher

Medium term scheduler

Long term scheduler

Memory controller

Process B moves from the running state to the ready state. To do this the O/S must:

Move its location in memory to the back of the ready queue

Move its location in memory to the front of the ready queue

Change the values of its queue pointers

Do nothing since the process will move itself

Data is transferred from cahce to registers in units of

Blocks

Words

Threads

Vectors

The stack pointer will give the maximum address of the stack

True

False

In the cache memory

On the disk

In main memory

None of the above
