Assignment: Networks and Data Communications
The primary objective of this assignment is to ensure that students learn the concepts of networking and data communications. This includes topology concepts and related technologies that are inter-woven together in an intricate manner. The manner and methods of data transmission, internetworking concepts as well as protocols used in data communications.
TASK LIST
The assignment consists of three tasks, which require students to carry out research, write a report on their findings as well as analyse the techniques used in data communication.
Task 2 - IPv4
The network layer protocol in the TCP/IP protocol suite is currently IPv4 (Internet Protocol, version 4).
IPv4 provides the host-to-host communication between systems in the Internet. Although IPv4 is well designed, data communication has evolved since the inception of IPv4 in the 1970s. IPv4 has some deficiencies that make it unsuitable for the fast-growing Internet.
To overcome these deficiencies, IPv6 (Internet Protocol, version 6), also known as IPng (Internetworking Protocol, next generation) was proposed and is now a standard.
Write a report on IPv4. Your report should include:
- An introduction to IPv4
- Description of IPv4 with a diagram of the IPv4 architecture.
- Disadvantages and issues of IPv4 that led to the development of IPv6.
Your report should consist of a minimum of 750 words.
If the word count exceeds 10% of the stated word limit, 10% of the total marks of the paper will be deducted from the total marks obtained.
Task 3 - Data encryption Techniques
Data encryption is one of the main techniques used in network security. Data encryption can be classified into 2 types Asymmetric Encryption and Symmetric Encryption. With the aid of diagrams, show how RSA Asymmetric and AES Symmetric encryptions work.
Your report should include:
- Introduction to Network Security
- Characteristics of RSA and AES encryption.
- Diagram of RSA Asymmetric encryption.
- Diagram of AES Symmetric encryption.
Your report should consist of a minimum of 750 words.
