OCR GCSE Computer Science 1.5 Systems software overview quiz quiz

Writing a word-processed document on behalf of the user

Editing and applying filters to a photograph for the user

Browsing web pages and loading websites for the user

Memory management, allocating RAM to programs

Several programs to run at once by sharing processor time

Two separate users to share a single keyboard at the same moment

A large file to be compressed so that it takes up far less storage

The whole disk to be encrypted so its data cannot be read if stolen

A person whose job is to install new hardware into a computer system

Software that translates between the operating system and a specific device

A type of cable used to connect a peripheral device to the computer's ports

A backup utility that copies the user's files to keep them safe from loss

File management

Memory management

User management

Peripheral management

Application software that does productive work for the user, like a spreadsheet

The physical hardware components found inside the case of a computer system

A particular type of operating system installed on most home computers today

Systems software that performs maintenance and housekeeping tasks

It reorganises fragmented files so each is stored contiguously, so the head moves less

It deletes all of the unused files from the disk so that there is more free space available

It permanently increases the speed at which the magnetic disk platters spin around

It encrypts the files on the disk so they cannot be read without the correct key

SSDs are always kept completely empty, so their stored files can never become fragmented at all

An SSD has no moving read/write head, so the position of file parts does not affect speed

SSDs are physically unable to store any file in fragmented pieces across the whole drive

SSDs automatically run their own backups, so defragmenting them would be pointless

Makes files smaller so they take up less storage and transfer faster

Reorganises the scattered parts of files on the disk so each is contiguous

Scrambles data with a key so it cannot be read without the key

Copies the selected files to another location to keep them safe from loss

Copies only the files changed since the last backup

Copies nothing at all, and merely checks the files

Deletes the old files to free up storage space

Copies all the selected files every time

Each backup is faster and uses less storage because only changes are copied

It is far simpler and quicker to restore from than a single full backup is

It copies absolutely everything every single time the backup is run on the disk

It never needs an initial full backup to be taken before it can be used at all

Calculating the result of a spreadsheet formula

Allocating RAM to running programs

Drawing a picture in a graphics package

Writing and sending an email message

Scrambles data with a key so it cannot be read without it

Controls the printer by translating between it and the OS

Reduces the size of files to save space and transfer faster

Manages user logins, accounts and the access rights of each user
