Networking Lesson 5

Do Now:
Question 1: Explain the purpose of a network cable.
Question 2: Identify the advantage of using a hub in a network

Network cables

• To connect together different devices, you need cables.
  

• They have plastic plugs that connect into sockets on devices.
  

• The cable is made up of a number of copper wires.
  

Hub

• A hub connects a number of computers together.
  

• Ports allow cables to be plugged in from each connected computer.

 

Servers

• Some networks will have a server.

• A server is a powerful computer which provides services.

• There are many different types of server, for example, a file server which stores files (i.e. text, images, sound, or video) that can be accessed by all devices on the network.

 

Router

• A router is used when we want to connect 2 networks together across distances. 

• A router forwards messages from one network to another. It acts as a gateway.

• A common job of a router is to join a home network to the internet via an internet service provider (ISP).
