TASK SHEET 1OBJECTIVEFrom the book ‘Networking and IOT’ you will be applying your theory knowledge gained to achieve the following Student Learning Outcomes (SLOs):

From ‘Unit 1 – Introduction to Computer Networks’: describe a computer network explain what information security is describe different types of hackers explain what a network topology is discuss the advantages and disadvantages of computer networks list computer networking media explain transmission bandwidth and duplex

From ‘Unit 2 – Network Models, Hardware, Protocols and Binary’: discuss the differences between peer-to-peer and client-server network models. state the purpose of network hardware. describe a network protocol. explain how data packets move across a network.

You will then practically design a LAN using network media and devices such as a switch, PCs and laptops and check the bandwidth between the devices.

EQUIPMENT REQUIREMENTSTerm book; pen/pencil, laptop/computer; Cisco Packet Tracer Software 7.x.

TASK INTRODUCTIONIn Part A, you will answer various theory questions covering unit 1 (Introduction to Computer Networks) of the book.In Part B, you will answer various theory questions covering unit 2 (Network Models, Hardware and Protocols) of the book.In Part C, you will design a LAN using a switch, two PCs and two laptops using the network simulating program, Cisco Packet Tracer
