Operating Systems (Assignment 06 - Memory Management)

The main memory accommodates

• CPU and user processes

• CPU and operating system

• Operating system and user processes

• All of these

The operating system is

• In the low memory

• In the high memory

• Either (A) or (B), depending on the location of the interrupt vector

• None of these

In contiguous memory allocation

• Each process is contained in a single contiguous section of memory

• All processes are contained in a single contiguous section of memory

• The memory space is contiguous

• None of these

The relocation register helps in

• A different address space to processes

• To protect the address spaces of processes

• Providing more address space to processes

• None of these

With relocation and limit register, each logical must be __________ the limit register

• Equal to

• Less than

• Greater than

• None of these

The operating system and the other processes are protected from being modified by an already running process because

• They have a protection algorithm

• They are in different memory spaces

• They are in different logical addresses

• Every address generated by the CPU is being checked against the relocation and limit registers

Transient operating system code is code that

• Is not easily accessible

• Comes and goes as needed

• Stays in the memory always

• Never enters the memory space

Using transient code, ___________ the size of the operating system during program execution

• Changes

• Increases

• Maintains

• Decreases

When memory is divided into several fixed partitions, each partition may contain __________.

• Exactly one process

• At least one process

• Multiple processes at once

• None of these

In fixed sized partition, the degree of multi-programming is bounded by ________.

• The memory size

• The CPU utilization

• The number of partitions

• All of these
