Introduction
This coursework is aimed to show 3 parts in the field of Computer and Network Fundamentals: Part A- Number Systems, Part B-Working of computer systems and software and Part C-Computer build based on certain requirements.
Part A:Calculations Question number | Answers | 1. | 13910 | 2. | 3218 | 3. | 8316 | 4. | AE16 | 5. | -4810 | 6. | FA16 | 7. | 3A16 | 8. | F516 | 9. | 5653310 | 10. | 4CDC16 | 11. | 9 bytes | 12. | 4C=L | 13. | SCSI Hardware MP |
Part B:Research Question
B1. Explain the purpose of MPEG encoding. Give an example of it’s implementation and why it is used in this case.
Ans: MPEG, short for Moving Picture Experts Group was established in the year 1988 by a group of experts formed by the ISO (International Organisation for Standardisation) and the IEC (International Electrochemical Commission) to set a standard for audio and video compression and transmission.MPEG has many types such as MPEG-1, MPEG-2, MPEG-4 etc, of which MPEG-4 is the most widely used encoding standard.
The purpose of MPEG encoding is to make audio and video files easy for compression and transmission. Video images take up a lot of memory. For a full motion video to appear without any disturbance images should appear at a minimum rate of 25 frames per second. This is achieved by compression the data into small bits which can be easily transmitted and then decompressed. The advantage of MPEG encoding is that it has a high data compression rate. This is because it only stores the changes that take
