Y10 Network Recap

What is a Local Area Network

• A network that covers the local area

• A network that covers a large geographical area

• A network that covers a small geographical area

• A network made up of smaller networks

What is a wide area network

• A network that covers a large geographical area

• A network that would typically be found in an office

• The Internet is an example of a LAN

• A network that covers a small physical area

What are the three factors to consider when looking at the advantages and disadvantages of networks

• Speed, Reliability, Portability

• Performance, Speed, Durability

• Communication, Collaboration, Sharing Resources

• Cores, Clock speed, Cache

Martha has set up a network by plugging a cable from her laptop into the computer next to her. What type of network is this?

• Client-Server

• Peer-to-Peer

• LAN Party

• WAN Access

How would the number of users affect network performance?

• More users means that they will share more of the resources, this is a good thing as it gives you access to more things

• More users is a bad thing because the bandwidth is divided out among everyone - more users, less bandwidth

• Less users is a bad thing because without them, there would be no services like websites or the internet

• Less users is a good thing because each user has its own bandwidth and you need to keep it low to boost performance

What is error rate?

• This is the rate at which errors occur on a network

• This is the number of packets received divided by the time taken to receive them

• This is the how many errors occur in 1 second

• This is the number of data packets that are either lost or corrupted over time

If you wanted to stream high definition TV, which would be the most suitable media

• Fiber optic

• Wi-Fi

• Online Streaming Platform I.e. Netflix

• It would need a direct connection with the media source

What are the advantages of Wi-Fi as a media choice?

• It covers a large geographical area compared with other wired options

• It is means that the user is mobile and not fixed to a single location

• It is secure because anyone can transmit data

• It is the fastest media choice

What do we mean by 'Bandwidth'?

• This is how much traffic travels across a network in a given amount of time

• This is how fast data travels across a network

• This is the amount of time taken for each data packet to arrive at its destination

• This is how fast something can be downloaded

If the latency is high, what does this mean?

• The network is working fast - Data packets are arriving early to their destination

• The network is working too hard, it needs to slow down

• The network is working slow - data packets are taking too long to get to their destination

• the network is not working hard enough, it needs to speed up
