2.

The _________ generates the primitive commands that control a peripheral device.

CPU
IOCS
Memory Manager
Process Manager

Correct Answer

A. IOCS

Explanation

IOCS stands for Input/Output Control System. It is responsible for generating the primitive commands that control a peripheral device. This includes tasks such as initializing the device, sending commands to the device, and receiving data from the device. The IOCS acts as an interface between the CPU and the peripheral device, ensuring that the device functions correctly and can be controlled by the CPU. Therefore, the IOCS is the correct answer for this question.

The boot sector contains

Instructions to shut down the computer
Instructions to load the operating system into memory
The disk directory
A queue of programs to start up

Correct Answer

A. Instructions to load the operating system into memory

Explanation

The boot sector is a small section of a computer's hard drive or other storage device that contains instructions on how to start up the computer. It includes the necessary code to load the operating system into memory, which allows the computer to begin running. This process is essential for the computer to function properly and for users to be able to access and use their operating system and other software.

A resident operating system routine is one that

resides on secondary storage
Is loaded as needed
Loads other programs
Stays in memory

Correct Answer

A. Stays in memory

Explanation

A resident operating system routine is a program that remains in memory while the computer is running. It is not loaded from secondary storage every time it is needed, but rather stays in memory to be accessed quickly whenever required. This allows for faster execution of the routine and efficient use of system resources.

5.

The transient are of memory is used to hold application programs and transient operating system routines.

True
False

Correct Answer

A. True

Explanation

The transient area of memory is indeed used to hold application programs and transient operating system routines. This area of memory is temporary and is used for storing data that is currently being processed or executed. It is different from permanent storage, such as hard drives or solid-state drives, which are used for long-term storage of data. In the case of the given statement, it is correct that the transient area of memory is used for holding application programs and transient operating system routines.

Multiprogramming is

The ability of the computer to run programs built using compilers, interpreters, or assemblers
The ability of the computer to run multiple programs concurrently
the ability of the computer force a user to login before running programs
The ability of the computer to communicate with other programs running remotely

Correct Answer

A. The ability of the computer to run multiple programs concurrently

Explanation

Multiprogramming refers to the ability of a computer to run multiple programs concurrently. This means that the computer can execute multiple programs at the same time, allowing for efficient utilization of system resources. This is achieved through techniques such as time-sharing, where the CPU is shared among multiple programs, allowing each program to execute for a short period before switching to another program. Multiprogramming improves overall system performance and responsiveness, as it allows for better multitasking and efficient utilization of system resources.

Which of the follhttp://www.proprofs.com/quiz-school/submit2.phpowing best describes a virtual memory system?

All of the program's pages reside on disk, and are executed on disk by the processor
Pages that are currently needed are brought into memory; the rest of the program's pages are swapped to disk
The program's pages are converted to object code only when they need to be executed
All of the above

Correct Answer

A. Pages that are currently needed are brought into memory; the rest of the program's pages are swapped to disk

Explanation

A virtual memory system is a memory management technique that allows a computer to use secondary storage (such as a hard disk) as an extension of its primary memory (RAM). In this system, only the pages of a program that are currently needed are loaded into the main memory, while the rest of the program's pages are swapped out to the disk. This allows for efficient memory utilization and enables the computer to run programs larger than the available physical memory.

Dynamic address translation:

Converts a programmer's symbolic address into an absolute address
Converts a bus address into a peripheral's address
Converts a transient memory location into a resident memory location
Converts a relative address into an absolute address

Correct Answer

A. Converts a relative address into an absolute address

Explanation

Dynamic address translation is a process that converts a relative address, which is an address that is relative to a specific point or location, into an absolute address, which is a fixed address that directly corresponds to a specific memory location. This allows the programmer to work with relative addresses, which can be more convenient and flexible, while the system handles the translation to the actual memory location where the data is stored.

A programmer is concerned with , and the operating system is concerned with _ to the device.

Logical I/O , physical I/O
Physical I/O , logical I/O
Physical I/O , peripheral I/O
Logical input , logical output

Correct Answer

A. Logical I/O , physical I/O

Explanation

A programmer is primarily concerned with logical I/O, which refers to the input and output operations performed by a program at a higher level of abstraction, such as reading from or writing to a file. On the other hand, the operating system is concerned with managing the physical I/O, which involves the actual transfer of data to and from the device, such as sending data to a printer or reading data from a hard disk.

Dynamic memory management is a strategy in which

Memory is split into fixed partitions
Memory is treated as a pool of unstructured free space
Memory is dynamically increased by adding more RAM chips
Memory is dynamically refreshed 500 times a second

Correct Answer

A. Memory is treated as a pool of unstructured free space

Explanation

Dynamic memory management is a strategy where memory is treated as a pool of unstructured free space. This means that memory is not divided into fixed partitions, but rather allocated and deallocated as needed. This allows for more efficient use of memory, as it can be dynamically allocated to different processes or programs based on their needs. It also allows for better memory utilization, as unused memory can be freed up and used by other processes.
