What is a (NIC) Network Interface Card ?

A network interface card, or NIC for short, is a piece of hardware that lets your computer talk to other computers or devices on a network. It's like a translator between your computer and the network, allowing them to exchange information and communicate with each other.

What is a Hub/Switch?
  • A Hub and a Switch are both networking devices that allow multiple devices to connect to each other and communicate within a network.

  • Both of them allow communication between devices

  • A Hub sends information to all devices.

  • A Switch sends information to certain devices.

What is a Modem?
A modem, short for "modulator-demodulator," is a device that converts digital signals from a computer or other digital device into analog signals that can be transmitted over telephone lines, cable lines, or other communication channels.

What is Wireless Access Point (WAP)
A wireless access point (WAP) is a networking device that allows wireless devices to connect to a wired network using Wi-Fi. It acts as a central hub that enables wireless devices such as laptops, smartphones, and tablets to connect to a network and access the internet or other network resources without requiring a physical cable connection.

Slide 19 - Question de remorquage

What is a Router?
  • A router normally connects two different networks together i.e Your home network and the internet. 

  • Allows all the devices at your home to communicate with the outside world, using the internet.

  • They normally work with WAPs (Wireless Access Points). So mobile devices and laptops can connect to them.

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 24 - 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 26 - 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 30 - Diapositive

Do you think your 'Network' at home, would be different to the one at school?

Slide 31 - Question ouverte

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.

Slide 34 - Diapositive

B
A switch and a hub are the same thing.
C
A switch is used for gaming, while a hub is used for streaming.
D
A switch is used for cooking, while a hub is used for storage.
