1.5 Network Topologies, Protocols and Layers.

1. What is a mesh network?

   • some or all of the workstations/devices are connected directly with each other.
     • usually connected to the node they exchange the most data with.

2. Whats a star Network

   • Most Common network topologies

3. Benefits of Ethernet cables.

   • stable connection.
   • reduced possibility to hacking.
   • more secure.
   • faster traffic speed.
   • good quality signal.

4. Benefits of wifi.

   • cheap to set up.
     • more vulnerable to hacking.
       • signal quality will reduce through walls.
   • user not tied down to specific location.

5. encryption.

   • method of scrambling data with a key code which makes no sense.
     • public wifi or an open resource can be encrypted.

6. What is a network?

   • is a number of computers linked together to allow them to share resources.

7. Topologies

   • Arrangement of a communications network
     • Signals travel from node to node on the bus
     • Bus topologie is a known as a tree topologie

8. Layers

   • Network Communication standardised
   • Troubleshooting easier
