Write a report of 3,000 words (+/- 10%). I have suggested word counts for each criterion and further guidance will be given in the classroom:
Identify how an analogue telephone system (POTS) is used to transmit digital data. Look at how data is encoded/modulated and identify different encoding/modulation methods. For this you may want to consider analogue vs digital data/networks and different encoding/modulation techniques.
(Word count 500) (1.1, 1.2)
Describe how data is transferred and what methods are used. For this you may want to consider protocol stacks and how binary data can be transmitted on different types of networks.
(Word count 250) (1.3)
Describe the benefits of computer networks and identify network topologies and types such as:
• Star
• Bus
• Ring
• Mesh
• LAN
• MAN
• WAN
Include diagrams to reinforce your explanations. For this you may want to consider both physical and logical topologies.
(Word count 500) (2.1, 2.2)
Media access control refers to the need to control when computers transmit. Identify the two main methods of controlling access to network media. For this give a brief summary of the functionality of each method and identify which type(s) of network each method is used with.
(Word count 300) (2.3)
Describe the following different types of network media:
• Fibre optic cable
• Coaxial cable
• UTP/STP CAT cable
• Wireless
For this you may wish to discuss performance data alongside the advantages/disadvantages of each type of media.
(Word count 250) (3.1)
Describe the purpose of the following types of network hardware:
• Network card
• Switch
• Router
For this you may wish to give example products of each type and identify the role that each device has on a network.
(Word count 250) (3.2)
Select a choice of ISP/network connection type for a domestic household which comprises of a mother, father and three children which will allow the download and playing of online games and unlimited music/video streaming. For this you may wish to justify your choice on the grounds of cost, speed and download size and any other factors that you think are appropriate.
(Word count 400) (3.3)
Identify the OSI and TCP/IP models and how they are used in networks. For this you may want to consider introducing and discussing diagrams of the models given.
(Word count 250) (4.1)
Describe network addressing techniques and what their function is. For this you may want to consider discussing MAC, IPv4, and IPv6 addresses and automatic vs static address allocation.
(Word count 250) (4.2)
Identify the purpose of common network protocols and standards and why they are used. For this you may want to consider why we have common protocols and standards and the benefits that this gives us.
(Word count 250) (4.3)
