1. MESH NETWORK

   • Where some or all of the workstations or other devices are connected directly to each other. Most are usually connected to the node that they share the most data with

2. STAR NETWORK

   • In a star network, each device is connected by an individual cable directly to the server. Star Networks are usually the layout of choice In schools and offices as they tend to be the most reliable of the topologies

3. Ethernet Factors

   • Stable Connection
   • Reduced Possibility To Be Hacked
   • More Secure
   • Faster Traffic Speed
   • Generally will have a good quality signal

4. Wifi Factors

   • Cheap Set up costs
   • More Vulnerable To Hacking
   • The signal quality will reduce through walls or obstructions
   • can connect to multiple devices without extra hardware
   • Interference Can Occur
   • Less Disruption caused to the building due to no wires being installed
   • User Not Tied Down To A Specific Location
   • May not be able to receive signal
   • The connection is not as stable as wired networks
   • Tend to have slow transfer speeds

5. Wi-Fi (Wireless Frequency)

   • Radio Waves are used to transmit data packets without the need for wires
   • This method is slower and more vulnerable to attack but removes the need for cabling and wires
   • This Means That It Can Be Set Up In Remote Locations Such As In Vehicles, Parks Or On Planes ETC.

6. Encryption

   • Encryption is a method of scrambling data with a key code which makes no sense
   • On an open or public Wi-Fi network anyone can join and sniff out packets of data from other users
   • therefore encryption is used if intercepted the data will have no meaning
   • In Order to read the data the user is required to decrypt the data using the key
