Key Objective: To understand the key components, which form a network.
 All 
  • To be-able to describe a Network.
  • To identify what the key components that make up a Network are.

Most 
  • To be-able to describe what the key components of a Network do. 

Some 
  • To be-able to explain where we might need a Network.
  • To explain the suitability of a Network.

Slide 5 - Video

Where do you think we might use a 'Network'?

Slide 6 - Slide

The definition of a 'Network'
A 'Network' is a group of two or more computer systems linked together so they can share information and resources.

Slide 7 - Slide

Benefits of using a network over a standalone device?

Slide 8 - Mind map

Research Task - What is a NIC (Network Interface Card) ?

Slide 9 - Open question

Network Interface Card (NIC)
  • Allows device to connect to network
  • gives an IP address
  • uses a cable or wireless 

Slide 10 - Slide

Research Task - What is a Network Hub/Switch?

Slide 11 - Open question

HUB
  • Connects devices together (its usually central in the network)
  • sends any signal it gets to everything connected to it 

Slide 12 - Slide

Switch
  • Same as the hub but stores IP addresses of connected devices
  • So it send thing to the correct device and not all of them 

Slide 13 - Slide

Hub
Switch
This device information to all devices.
This device sends information to specific devices.

Slide 14 - Drag question

Research Task - What is a Network Router?

Slide 15 - Open question

Router
  • Connects two different networks together
  • connects your home to internet
  • redirects data packets

Slide 16 - Slide

Research Task - What is a Wireless Access Point (WAP)?

Slide 17 - Open question

Wireless Access Point (WAP)
  • Creates a "hotspot"
  • Allows wifi connection to a wired network 

Slide 18 - Slide

Do you know any types of cable used in networking?

Slide 19 - Mind map

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.




Slide 20 - Slide

What does an Ethernet cable look like?

Slide 21 - Slide

What is a Topology?
Is the layout of the network
There are two main types:
  • MESH
  • STAR

Slide 22 - 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.

This is almost always a wireless network (can you think why!)

Slide 23 - Slide

What does a Mesh Topology look like? 

Slide 24 - 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/switch, which acts as a central point of control for the network.

Slide 25 - Slide

What does a Star topology look like?

Router
Ethernet Cables
Devices

Slide 27 - Drag question

What our Home 'Networks' look like

Slide 28 - Slide

Do you think your home 'network' would be different from the school 'network'?
Yes
No
Maybe
I don't know

Slide 29 - Poll

The 'School Network'

Slide 30 - Slide

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

Slide 31 - Open question

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 32 - Slide

What is a Router?
A
A networking device that forwards data packets.
B
A device used to cut wood.
C
A musical instrument.
D
A kitchen appliance for making toast.

Slide 33 - Quiz

What is the difference between a switch and a hub?
A
A switch sends data to a specific device, while a hub sends data to all connected devices.
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.
