1.5 Networks

Which network features all devices connected to all/multiple other devices?

• Mesh

• Star

Which are features of a Mesh Network?

• Data can be transmitted from different devices simultaneously.

• Devices are dependent on a central sever.

• The network uses terminators

• The Server is usually based in the middle of the network

• If one device fails there is an alternative route for the data

Which are features of the Star Topology?

• Adding/removing devices is easy

• Less network traffic/collisions

• Doesn't rely on the central server being operational

• Doesn't use any cables

• If one client fails the rest of the network will continue to operate as normal

Which are disadvantages of WiFi?

• It makes users less mobile

• It increases Health & Safety issues by removing wires

• It is requires extensive use of expensive cables

• Tend to have slow transfer speeds

• It is more vulnerable to hacking

• False

What are benefits of a wired network over a wireless network?

• Decreased costs

• No technical knowledge needed

• Faster data transfer speeds

• Impossible to hack

• More stable connection

What are benefits of using a mesh network over a star network?

• Cabling is often easier to follow

• A mesh has more networks than a star

• Adding more devices won't slow down the transmission of data

• You haven't got to buy expensive cables as it's always wireless

• One component failing won't stop the network from performing
