The____________________________of an operating system permits interaction with the computer system and needs to be appropriate to the intended user.

Windows icons menus and pointers

What is an interrupt?

A process that forcesexecuting processes to be stopped to allow another to get CPU time

A user interaface for novice users

Hardware that connects operating systems

Interrupts can be generated by

Hardware: e.g. power button pressed.

Software: e.g. a program needs to run a routine (for example, to automatically save a document being edited by a user).

Time triggered: e.g. in data logging applications.

Peripheral: e.g. user has moved the mouse.

Which interrupt is the highest priority?

Hardware: e.g. power button pressed.

Software: e.g. a program needs to run a routine (for example, to automatically save a document being edited by a user).

Time triggered: e.g. in data logging applications.

Peripheral: e.g. user has moved the mouse.

Which interrupt is the second highest priority?

Software: e.g. a program needs to run a routine (for example, to automatically save a document being edited by a user).

Hardware: e.g. power button pressed.

Time triggered: e.g. in data logging applications.

Peripheral: e.g. user has moved the mouse.

Which interrupt is the third highest priority?

Time triggered: e.g. in data logging applications.

Hardware: e.g. power button pressed.

Software: e.g. a program needs to run a routine (for example, to automatically save a document being edited by a user).

Peripheral: e.g. user has moved the mouse.

Which interrupt has the least highest priority?

Peripheral: e.g. user has moved the mouse.

Hardware: e.g. power button pressed.

Software: e.g. a program needs to run a routine (for example, to automatically save a document being edited by a user).

Time triggered: e.g. in data logging applications.

Key design goals for memory management are

Allocate enough memory so each process can run

Split memory up so that it can be allocated to processes (paging/segmentation)

Ensure security so that other processes cannot access each other’s data

Defragment data that has been split

Key design goals for memory management are

Extend memory by using virtual memory

Allow efficient sharing of memory

Use of the control panel to splt up tasks and applications

Allocation of RAM _______________________

allows RAM to be shared without worrying about accidentally overwriting each other

allows operating systems to boot up

Which statement is true

RAM stores programs/ data used by the CPU

ROM contains the operating system

an series of pixels used to represent an image

Virtual memory is used

when the RAM is not enough to contain all of the programs and data currently being used

every other time a program is used

as a secondary storage medium for long term storage of documents

when the CPU is getting overheated

Which of the following are the advantages of virtual memory? (Select two.)

Degree of multiprogramming is higher.

Execute even processes whose larger than the size of RAM.

Decrease the average memory access time.

Decrease the effective memory access time.

Responsibilities of OS include

Handling "interrupts" generated by the I/O controllers

Making external devices to work properly

Creating instructions to connect user's PC to the local network

Finding ways for student to answer this question

What is User's Interface?

The space between computer and user's actions

The space between user and computer

The space between computer and software

How does the OS provide security

Using passwords or backing up files

keeping a check on other processes

making the communication possible between the input and output devices and the computer

Allocating areas of memory to different programs so that each program can run effectively

What is the difference between paging and segmentation in memory management?

Paging splits the process to be loaded into equal size blocks

Paging splits the process to be loaded into variable sized, logical blocks

Paging allocates frames to hold the data on the hard drive

Paging is used on Windows computers, segmentation on MacOS
