What is a Topology?
A network topology refers to the physical or logical arrangement of a computer network. It describes how devices and nodes are connected to each other and how they communicate with one another.

Slide 17 - Slide

What is a Mesh Topology?
A mesh topology is a type of network architecture in which each device in the network is connected to every other device directly.

Slide 18 - Slide

What does a Mesh Topology look like? 

Slide 19 - Slide

What is a Star Topology?
A star topology is a type of network architecture in which all devices are connected to a central hub or switch. Each device on the network has a single point-to-point connection with the hub, which acts as a central point of control for the network.

Slide 21 - Slide

Packet Switching 
Data is divided into small packets and then sent individually to their destination, with each packet taking its own route through the network.

The 'School Network'

Slide 25 - Slide

What are the main differences?
Network Switches: A school network often has multiple network switches, which allow multiple devices to connect to the network and communicate with each other.

Server Hardware: A school network may have one or more servers, which are used to run network applications such as email, student information systems, and learning management systems.

Network Security Appliances: School networks typically have more advanced network security appliances than a home network, such as firewalls, intrusion detection and prevention systems, and content filters.
