What is a LAN?
A network that covers a small geographical area, located on one site
A network that connects WANs that are in different geographical locations
A network that connects only through a wireless connection
A network that connects only through Ethernet cables
Tick all advantages of using a LAN:
Sharing files is easier
You can share hardware such as printers
You can install and update software on all computers at once
You can communicate cheaply and easily
What is a WAN?
A network that connects different LANs that are in different locations
The network that is the Internet
A network that covers a small geographical area located on a single site
A network that uses star topology
How else is a WAN different from a LAN?
Organisations hire infrastructure from telecommunications companies who own and manage the WAN
It is much cheaper and more easy to set up
It is often found in schools, universities and businesses
Is the internet an example of a LAN or a WAN?
What is bandwidth?
The amount of data that can be transferred in a given time
The are that the network you are using covers
The length of the cables connecting the network
The number of devices connected to the network
Wired connections are generally faster and more reliable than wireless
What is a Network Interface Card?
A n internal piece of hardware that allows a device to connect to a network
A card that tells you how to connect your device to a network
A built in piece of hardware that connects to one network that your computer will use (but not more than one network)
NICs only exist for wired connections
What are switches?
They connect devices to a LAN
They switch the networks that the computer is using to make the connection secure
They change the bandwidth of the network
What so switches do (in more detail)?
They receive [blank_start]data[blank_end], in units called [blank_start]frames[blank_end], from [blank_start]one device[blank_end] and transmit this [blank_start]data[blank_end] to the device on the network with the correct [blank_start]MAC[blank_end] address.
What are routers?
They transmit data between networks by directing packets to their destination
They connect devices to the internet
They connect devices to LAN networks only
How many different networks are routers always connected to?
at least 1
at least 2
three or more
What are the two most common Ethernet cables?
How many copper wires do Ethernet cables contain?
How many copper wires are coaxial cables made from?
What is the job of the layer of metallic mesh that is found around coaxial cables?
It shields the cable from outside interferance
It protects the cable from being broken
It ensures that some data can enter but some data cannot
How is data transmitted in Fibre Optic Cables?
What type of waves do wireless use to transmit data?
What is a Wireless Access Point (WAP)?
A switch that allows a device to connect wirelessly
A location where you can get a wireless connection
