AQA GCSE Computer Science 3.5 Fundamentals of computer networks overview quiz quiz

A network covering a large geographic area using third-party telecommunications infrastructure

A single standalone computer that has no network connections to any other device

A network covering a small area usually owned by one organisation

Another name for the worldwide internet that links networks together

All sharing one single backbone cable that runs between every device

Joined in a single closed ring that passes data around in one direction

Directly connected to every other device with a separate dedicated link

Each by its own cable to a central switch

If the central backbone cable fails, the whole network goes down

It wastes cabling because every device needs its own dedicated link

Each device must have its own separate switch in order to communicate

It is physically unable to carry any data between the connected devices

It is generally slower and far less secure than a wireless link

It is faster, more reliable and more secure

It is unable to transfer files between connected computers at all

It always requires encryption before any connection will function

To make the wireless signal travel a much greater distance

To speed up the connection by compressing the transmitted data

So intercepted data cannot be read without the key

To reduce the number of devices that are able to join the network

To store the data on a network permanently so it is never lost

To physically connect the cables that join the devices together

To display web pages inside a browser on the connected computer

A set of agreed rules that lets devices communicate

FTP

HTTP

SMTP

IMAP

To deliberately make networks run more slowly so that the data is far easier to monitor

To completely remove the need for any protocols when devices communicate over a network

To break a complex task into independent parts that can be changed separately

To increase the number of physical cables required to join the devices on a network

Scans and removes viruses from infected files stored on the computer

Encrypts all of the files stored on the network so they stay private

Speeds up the CPU so the computer can process network data faster

Monitors and controls traffic entering and leaving a network

Allows only devices with an approved hardware address to connect

Scrambles the data travelling on the network so it cannot be read

Checks a user's password before they are allowed to join the network

Speeds up wireless signals so devices can transfer data more quickly

HTTP

HTTPS

Telnet

Ethernet
