In this assignment, you will produce a serial publication 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 render secern forP5 Describe the principles of signal theory1. Signal TheoryWith the promote 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. circumscribe 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 go away evidence forP6 Describe different transmission methods used1. Describe with the aid of drawings the features and benefits of the following t ransmission methods a. Coaxiali. Thinnetii. Thicknetb. Optical Fibrei. Single modal valueii. Multi Modec. Twisted Pairi. Unshieldedii. Shieldedd. Wireless solutionsRadio-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/microwaveSatellite-vi. What is a communication major planet?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. ALOHA2. FDMA3. TDMA4. CDMAhttp//www.cse.wustl.edu/jain/cis788-97/ftp/satellite_data/index.htmTask 3 (M2)This task will impart evidence forM2 Explain why particular transmission methods are chosen in particular situationsBased on the i nformation 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 forD2 Compare the effectiveness of different transmission methodsFor 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.
