1. advantages.

   • WAN advantage: offer a distinct privacy and security advantage, Network Performance Consistency: Equally important, your data does not have to compete with other Internet data for bandwidth as your communications travel between destinations.
   • LAN advantages: ostly resources such as printers can be shared by all of the computers, Software can be shared, and upgrading is easier too.

2. WAN disadvantages.

   • WAN disadvantages: Low bandwidth, easy to lose connection, Costs for equipment and technology is very expensive for WAN.
   • LAN disadvantages.
     • LAN disadvantages: Poor scalability, Investment in Higher Costs due to server systems

3. LAN

   • LAN- a network contained in a single geographical location or oganisation

4. WAN

   • WAN- a network that spans a large geographical area, or multiple organisations, often consists of multiple LAN's networked together.

5. IP address

   • A unique value assignment to energy computer on a network, used to identify it.

6. Network- a group of computers connected to each other for easier communication

7. Mesh Topology

   • The internet is just a giant mesh of computers which is a route-finding algorithm which is used to find the lowest cost between two nodes

8. Mesh disadvantages: While a mesh network like the Internet is very reliable, it has a big downside when compared to other topologies like a star.

   • Mesh advantages: Rather than using a star, bus or ring topology, each node is connected to one or more other nodes in an ad-hoc manner.
