Assignment-2 (Brief)
Unit No. 10
Unit Title: Communication Technologies
P/M/D Criteria covered:
(P5 – P6 – M2 – D2)

Learning outcomes – On completion of this unit you should:

1Understand the communication principles of computer networks

2Know the main elements of data communications systems

3Be able to implement different forms of network communications.

Scenario

A client wishes to know more about the issues surrounding the transmission of data. In this assignment, you will produce a series of mini reports to demonstrate your understanding of the various aspects of data transmission and the principles of signal theory.

Task 1 (P5)

This task will provide evidence for:

P5 Describe the principles of signal theory

1. Signal Theory:
With the aid of a diagram explain how data is represented in a digital format. What is a bit?
What is a data packet?
Draw a data packet and explain the individual parts.
Explain synchronous and asynchronous transmission.
Define bandwidth and give four common measurements from slow to fast (e.g. Bits Per second (bps) being the lowest). What is data compression and how is it beneficial to a network?

2. You should also explain with the aid of clearly labelled diagrams, how data gets from one point to the other by describing the following: Simplex, half-duplex and full-duplex.
Serial and parallel communication.

Task 2 (P6)

This task will provide evidence for:

P6 Describe different transmission methods used

1. Describe with the aid of drawings the features and benefits of the following transmission methods: a. Coaxial:
i. Thinnet
ii. Thicknet
b. Optical Fibre:
i. Single Mode
ii. Multi Mode
c. Twisted Pair:
i. Unshielded
ii. Shielded
d. Wireless solutions:
Radio-
i. Explain how computers convert digital signals into radio waves. ii. List three strengths and weaknesses associated with radio transmission.

Microwave-
iii. What is microwave?
iv. What are the main benefits of using microwave for data transmission? v. Explain point-to-point and point-to-multipoint microwave with suitable examples. http://www.intelephony.com.au/Networking/microwave

Satellite-
vi. What is a communication satellite?
vii. What are the three main categories of satellite with regards to their position in orbit. viii. Explain the following MAC protocols for satellite links: 1. ALOHA
2. FDMA
3. TDMA
4. CDMA

Task 3 (M2)

This task will provide evidence for:

M2 Explain why particular transmission methods are chosen in particular situations

Based on the information produced for (P6) create a series of scenarios to aid your explanation of why certain transmission methods are chosen in particular situations.

Task 4 (D2)

This task will provide evidence for:

D2 Compare the effectiveness of different transmission methods

For this part of your assignment develop a detailed report comparing the effectiveness of the transmission methods described in P6.

*Note: your report must focus on the good and bad points and not just be a description of the various methods.
