Slide 20 - Question ouverte

What is an Ethernet Cable?
  • An Ethernet cable is a type of cable used to connect devices, such as computers or routers, to a network. It is a physical cable that allows data to be transmitted between devices.

  • The cable contains several wires that carry the data signals, and it typically has a plastic connector on each end that can be plugged into a network port on a device or a network switch.

  • There are two types CAT5 and CAT6. They both have different speed capabilities.

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 23 - Diapositive

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 24 - Diapositive

What does a Mesh Topology look like? 

Slide 25 - Diapositive

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 26 - Diapositive

What does a Star topology look like?

Slide 27 - Diapositive

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 32 - Diapositive

What do you think the difference is between your home network and school network?

Slide 33 - Question ouverte

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.
