Include performance data. 3.1 Explain how computers are connected and data is transmitted around the following topologies including performance data. STAR, BUS, RING and MESH. Include diagrams to reinforce your explanations. 4.1 Explain the meaning of the terms, LAN, MAN, WAN, giving performance data. Supply diagrams to reinforce your explanations. 4.2 Describe different network media, giving performance data. FIBRE OPTIC, COAXIAL, CAT6. 4.3 Describe the purpose of different network hardware giving performance data. SWITCH, ROUTER, NETWORK CARD. Give details of how they handle data transmission. 5.1 Explain the difference between internet and intranet and how they can be connected. Include information on how you use the Internet to access resources on the College Intranet. 5.2 Explain how two computers talk to each other over an Ethernet local area network. Include information on data transfer rates. 6.1 Create a comparison chart showing the following frequencies used in a wireless network and explain what their advantages are over each other. A,B,G,N and AC. Include the channel option for 2.4Ghz and 5Ghz range. 6.2 Implement basic security on a wireless network. Set up a wireless network and create a SSID and secure the network with a password using WPA2 AES encryption. Explain with the use of screen shots the reason for completing both tasks.
