WJEC GCSE Digital Technology Systems overview quiz quiz

Data is entered, the processor acts on it, and results are sent out

Files are compressed, stored and then deleted

A network sends data to every connected device

Software is analysed, designed and tested

A spreadsheet built into a word processor

A computer built into a larger device to control one function

A network that has no internet connection

A backup stored inside a hard disk

A LAN is wireless and a WAN is always wired

A LAN has more devices than a WAN

A LAN covers a small area; a WAN covers a large area

A LAN is faster than a WAN in every case

Files and printers can be shared

If the server or network fails, many users are affected at once

Data can be backed up centrally

Users can log in from any machine

Connects different networks together

Stores backups of network files

Translates domain names into IP addresses

Allows a device to connect to and communicate on a network

A switch connects devices within one network; a router connects different networks

A switch connects to the internet; a router connects devices in a LAN

A switch stores web pages; a router displays them

There is no difference; the terms mean the same thing

They are two names for the same global network

The internet is the network; the Web is a service of websites running on it

The Web is the cables; the internet is the websites

The internet only carries email; the Web carries everything else

Translates a domain name into the matching IP address

Encrypts data sent over the internet

Stores all the world's web pages in one place

Connects a home network to the internet

Requests resources from the client

Translates IP addresses for the client

Responds to requests by sending the resource back

Connects only to wireless devices

Editing photographs for the user

Managing memory by allocating RAM to running programs

Writing a user's report automatically

Carrying out a user's online banking

A web browser

A spreadsheet

A presentation package

Antivirus software

Reduces the size of files to save space and speed up transfer

Removes viruses from infected files

Connects the computer to a network

Schedules processor time between programs

The operating system

A device driver

A word processor

A firewall

The system is installed and users are trained

The requirements are investigated and gathered

The system is checked for errors using test data

The solution is built according to the design

It gathers the requirements for the system

It installs the system for the users

It finds and fixes errors so a faulty system is not released

It designs the screens and data structures

Normal data only

Normal, boundary and erroneous data

Only data that the system should reject

No data, because testing reads the code
