WJEC GCSE Computer Science Computer networks and the internet overview quiz quiz

Computers over a small area such as one building

Computers across different countries

Only wireless devices

Only one computer to the internet

A home network

A school network

The internet

A single switch

All computers are equal and share directly

It provides services, files and resources to client computers

It only connects to the internet

It has no role once the network starts

It needs a central switch to work

It cannot connect more than two devices

It always uses more cable than a star

If the main cable breaks, the whole network fails

To connect devices within a LAN and forward data only to the intended device

To connect different networks together

To translate domain names into IP addresses

To encrypt web traffic

To give a device a permanent hardware address

To connect different networks and route data between them

To store the user's files

To play sound through speakers

It lets devices move around freely

It needs no cables

It is generally faster, more reliable and more secure

It works without any hardware

The amount of data that can be transmitted per second

The number of devices on a network

The distance a signal can travel

The number of packets lost

So it can only travel on one fixed route

So the whole message must be resent if anything is lost

So encryption is no longer needed

So packets can travel independently and a lost one can be resent

A set of rules that govern how devices communicate

A piece of network hardware

A type of cable

A numerical device address

HTTP is for email; HTTPS is for files

HTTPS encrypts the data; HTTP does not

HTTP is faster and more secure

There is no difference

FTP

HTTP

SMTP

DNS

It changes every time the device joins a new network

It is used to route data across the internet

It is the same as a domain name

It is a unique, permanent address built into the NIC

Translates domain names into IP addresses

Stores all the web pages on the internet

Encrypts data sent to a server

Connects two LANs together

They store the data until the user logs in

They read each packet's destination IP address and forward it hop by hop

They use the MAC address to reach the final website

They send every packet on exactly the same route

The internet is the global network; the web is one service running on it

They are exactly the same thing

The web is the network; the internet is just web pages

The internet only works without the web
