Q

it use multiple central processors to serve multiple real-time applications and multiple users. Data processing jobs are distributed among the processors accordingly

A

Distributed Operating System

20
Q

The processors communicate with one another through communication lines (such as high-speed buses or telephone lines). These are called?

A

loosely coupled systems or distributed systems

21
Q

it runs on a server and provides the server the capability to manage data, users, groups, security, applications, and other networking functions.

A

Network Operating Systems

22
Q

is an operating system intended to serve real-time applications that process data as it comes in, mostly without buffer delay

A

Real-Time Operating Systems

23
Q

The time interval required to process and respond to inputs is very small

A

Real-Time Operating Systems

24
Q

The time interval required to process and respond to inputs is very small in Real-Time Operating Systems. what do you call this time interval?

A

response time

25
Q

it is used when there are time requirements are very strict like missile systems, air traffic control systems, robots, etc.

A

Real-time systems

26
Q

it is also known as Mobile OS which is built exclusively for a mobile device, such as a smartphone, personal digital assistant, tablet, wearable devices or other embedded mobile OS.

A

Handheld Operating Systems

27
Q

Device controller informs CPU that it has finished its operating by causing an

A

interrupt

28
Q

is a signal emitted by hardware or software when a process or an event needs immediate attention

A

Interrupt

29
Q

It alerts the processor temporarily to a high priority process requiring interruption of the current work process and then return to its previous task

A

Interrupt

30
Q

An operating system is not interrupt driven. True or False?

A

False

31
Q

is a signal created and sent to the cpu that is caused by some action taken by a hardware device.

A

hardware interrupt

32
Q

arises due to illegal and erroneous use of an instruction or data.

A

Software interrupt

33
Q

It often occurs when an application software terminates or when it requests the operating system for some service.

A

Software interrupt

34
Q

The operating system preserves the state of the cpu by storing registers and the program counter

A

Interrupt Handling

35
Q

operating systems sends signals to each devices asking if they have a request

A

Polling

36
Q

requesting devices send interrupt to the operating systems

A

Vectored interrupt system

37
Q

operation allows OS to protect itself and other systems components

A

Dual mode

38
Q

Provides ability to distinguish when systems is running user code (1) or kernel code (0)

A

Mode bit

39
Q

Some instructions designated as privileged only executable in kernel mode

A
40
Q

is a way for programs to interact with the OS

A

system call

41
Q

There is one main cpu capable of executing a general purpose instruction set including instructions from user processes

A

Single Processor System

42
Q

Also known as parallel system multicore

A

Multiprocessor System

43
Q

First appeared in servers and now in smartphones and tablet computers

A
44
Q

Most systems used a single general purpose processor

A
45
Q

Each processor is assigned a specific task A boss processor controls the systems and the other processor either look to the boss for instructions or have predefined tasks

A

Asymmetric multiprocessing

46
Q

The most commonly used In which each processor performs all tasks with the operating system. All processor performs all tasks within the operating system.

A

Symmetric multiprocessing
