Section 4 – Computer Networks Setting up a small network

Lesson Objectives By the end of this lesson you will be able to: Describe how to set up a small network involving access to the internet, Understanding the need to set up the use of a browser, and an ISP

Recap Using the knowledge learnt from your last theory lesson. Can you identify all the different types of network hardware that we have covered? Hubs Switches Routers Repeaters Bridges Network Cards Servers

Networks So, we have learnt about what networks are and what there components are but we haven't had a look at they all these pieces work together. We will be using a flash animation for the next task. This can be found in the relevant area of the department share.

Task 1 Using the network scenario sheet create the example network and answer the questions in your book.

Browser Short for Web browser, a software application used to locate, retrieve and also display content on the World Wide Web, including Web pages, images, video and other files.

Short for electronic mail, the transmission of messages over communications networks. The messages can be notes entered from the keyboard or electronic files stored on disk. Electronic-mail systems others have gateways to other computer systems, enabling users to send electronic mail anywhere in the world. Companies make extensive use of because it is fast, flexible, and reliable.

ISP Short for Internet Service Provider, it refers to a company that provides Internet services, including personal and business access to the Internet. For a monthly fee, the service provider usually provides a software package, username, password and access phone number.
