Operating System

Identify the basic function of an operating system

• limit specifies the the length of the segment

• easy to isolate error and to debug

• to ensure all the user tasks can be done properly

• to allow the system to enter the deadlock state then recover

Identify the CORRECT type of operating system structure based on the description in statement below.

"1. The earliest and the most common operating system

2. 2.Communicate directly with any other components "

• microkernel

• layered

• monolithic

• networked

Choose the CORRECT operating system structure.

• kernel

• microkernel

• single processor

• multiprocessor

Choose the type of operating system structure based on the statement in statement below.

-Includes only a small number of services within the kernel

• -Reduces the kernel services to only basic process communication and i/o control

• monolithic

• layered

• microkernel

• networked

Select the CORRECT concept of operating system that enables many programs to load at a time and allow them to share the attention of a single CPU.

• real time

• multitasking

• multiprogramming

• multiuser

Kernel is the main component of most computer operating system. Select the answer that describes the function of kernel.

• manage the computer resources and allow other programs to run and use these resources

• requests service from the operating system based on the monolithic kernel or microkernel

• organizes data in an efficient manner and is turned to the specific characteristics of the device

• provide an interface for users of an operating system which allows access to the service of a kernel

Identify the type of interface that allows the user type the command to perform any action in the operating system.

• menu interface

• command line interface

• graphical interface

• application program interface

Select the BEST statement that is related to the clustered system

• only one process can be run at a time

• share storage and is closely linked via local area network

• other program must wait until the CPU is free

• many processes can run simultaneously

Select the purpose of system call in operating system

• accept input and provide output by generating voice prompts

• program can request a service from an operating system kernel

• allow user to interact with electronic devices using images rather than text commands

• allow putting jobs in a buffer, a special area in memory or on a disk where a device can access them when it is ready
