1. Match’em up activity

2. Advs and disadvs of topologies.
What goes where
Ring
Star
Bus
Cable length restricts the number of devices that can be connected
Messages sent between two stations pass through all devices…no server needed
Centralised layout offers simplicity
It allows isolation of each device on a network
Suitable for small networks
The failure of any cable can cause network failure
As more devices are connected – the slower it gets
It relies on the correct functioning of the central hub – if that crashes – it all fails.
Any changes to stations can have performance issues on the whole network
Easy and cheap to install as a consequence of only a small quantity of cable

3. The order of communication on a network.
Stick it in order
A source of infomation
Transmitter to convert to compatible signals on the channel
A communication channel
A receiver to convert signals back so they can be read.
Destination for the information

4. Pros and Cons of networks
Users can share software stored in system
More straightforward to backup than standalones
Need to employ a manager to oversee
Stringent security measures needed such as firewalls to stop abuse.
Files can be shared
Pros
Comms by electronic means
Cons
Can share common peripheral devices (printers)
Risk of hacking especially over wide areas
The cost of construction as well as the servers is high
Security can be high – users cant see others profiles
Users can share viruses
Management of a large network is complicated , requires skill and knowledge
If a fault occurs access to files will be lost
Cost/effort is lower to maintain than stand alones
