Eduqas GCSE Computer Science networks and security overview quiz quiz

Large Area Network, covering a whole country and its major cities

Linked Access Node, covering just one device on a single desk

Long Access Network, covering the entire world and its continents

Local Area Network, covering a small area such as a building

A break in the backbone cable stops the whole network

It uses far more cabling than any other topology design

It cannot connect more than two devices to the shared cable

It requires an expensive central switch for every connection

A switch

A router

A network interface card

A repeater

Greater mobility for users moving around the building

No cabling required anywhere across the whole network

More stable bandwidth and better security

Far easier to add brand new devices without any setup

They are exactly the same thing and the two words mean one identical system

The web is the physical hardware while the internet is just the software that runs on top

The internet only carries email and nothing else can travel across it at all

The internet is the global network; the web is one service (linked pages) running on it

Translates domain names into IP addresses

Encrypts all web traffic before it is sent across the network

Stores every web page in the world on one central server

Blocks unauthorised network traffic at the boundary of a network

IMAP

SMTP

POP

FTP

It makes the network run much faster than an unlayered design

It removes the need for protocols altogether on the network

One layer can be changed without rewriting the others

It encrypts all data automatically as it passes between layers

Flooding a server with so many requests that it cannot respond to anyone

Trying many different passwords automatically until one of them finally works

Software that secretly encrypts a victim's files and demands a ransom payment

Sending fake messages pretending to be a trusted organisation to steal data

To make a service unavailable by flooding it with requests

To steal passwords by tricking users into typing them in

To encrypt the user's files and then demand a ransom payment

To read a database secretly through a poorly protected login box

By guessing user passwords automatically until one of them works correctly

By entering malicious SQL into an input field to manipulate a database

By flooding the network with so much traffic that the server stops responding

By disguising harmful malware as useful free software that people download

It scrambles data into ciphertext so it cannot be read without a key

It backs up all of a system's data automatically to a separate offsite location

It monitors and controls network traffic, blocking unauthorised connections

It authenticates users by scanning their fingerprint before they log in

Blocks unauthorised network traffic at the boundary of a network

Copies a system's data to a separate backup in another location

Tries many different passwords automatically until one finally works

Scrambles data into ciphertext so it cannot be read without the key

A full backup copies all data; an incremental copies only data changed since the last backup

A full backup copies only the changes since last time; an incremental copies absolutely everything

They are exactly the same process and the two terms describe one identical method

A full backup is always stored off site while an incremental backup is always stored on site
