Advantages Of Data Compression

| Zip or compress one or more files in an attempt to shrink the file size

There are many sub-groups of these discs, but the main types of discs are CD, DVD, and Blue-ray. The optical disc is placed into a DVD recorder and information is written to the disc. The data is written in contiguous format on the disc. A recorder will not write data to an optical disc if that data is bigger than the optical disc. A DVD disc can handle a data amount of 4.88 GB. The compression of an optical disc is handled by the program that is used to burn the disc. The data is written to an optical disc using a laser. This laser burns the data into the bottom of the disc. The use of different wave length of the laser actual help burn more data into the bottom of the disc. However, the drawbacks of an optical disc are that they cannot be placed in direct sunlight. The plastic that the disc is made of can warp in sunlight and corrupt the data on the disc. There is also the problem of scratches and dents making the surface of the disc hard for the laser to read.(AMERICAN,

Data is defined as useful raw material which is intended to be useful for both the originator and for the intended receiver. Data consists largely of facts and figures ideal for communicating the intended meaning. This data can be interpreted and can be categorised as follows;

The book states that there are three rules that coding methods should adhere to. When it comes to coding and decoding, a coding method needs to be followed by everyone properly. Users must be able to store, send, and retrieve code using the coding method. The coding method must be able to follow the goals of computer data representation which are compactness and range, accuracy, ease of manipulation, and standardization.

Chapter 7 discusses compression algorithms. Compressions are used often and sometimes we may not even be aware of it. The items we download or upload may be compressed in order to save bandwidth. Chapter 8 discusses the fundamental algorithms underlying databases (MacCormick, 7). This chapter emphasizes the techniques used to achieve consistency and to ensure that databases never contradict each other. Chapter 9 discusses the ability to ‘sign’ an electronic document digitally (MacCormick, 7). Chapter 10 discusses algorithms that would be considered great if it existed.

This unit we covered more specifics about how to implement compression. As part of that, we looked at different methods that can be used and what the benefits of each type would be. For the discussion assignment, I needed to implement Heap’s Law against the output of our programming assignment from last week. We needed to not only get the outcome of implementing the function but also determine how the information we obtained from the result could be applied to our understanding of what the program performed.

It converts the functions for the application layer data. It compresses the data allowing it to be encrypted and more secure. It represents the data in graphical formats such as in JPEG, BMP, MPEG etc. as well as characterising the characters into text or ASCII.

50 percentage of datagram will be overhead. IP and TCP will be 40 bytes plus 40 bytes of data make 80 bytes total.

Table I displays six solid binary images along with their corresponding compression ratios. On considering Run-Length coding, the alternative encoding scheme produces better performance than the other encoding scheme. On an average, the proposed algorithm performs well on comparison with the standard Huffman coding algorithm by approximately 1.58%.

The different formats used to store information will have varying file sizes. This is because some files

Data is the form of input, which can be produced into information. For example, 5000 could be the value of a piece of data that a business has. By adding context to this, for example if an organisation sold 1000 sandwiches in a week; this becomes information, which will influence important decisions

Additionally, utilizing an efficient data copy method can help reduce the total storage capacity consumed and therefore help reduce costs.

It is the type of disk in which the space is fixed. it doesn’t matter how much data you store.

Lossless compression is the technique of reducing the size of an image without any virtual loss of information. It is also known as reversible form of image compression since the image obtained after compression and then decompression resembles the original one. Typical compression ratios that can be achieved ranges from 1.5 to 3.6 [3].

The original video file is about 2GB in compare with the encoded video file about 1.4MB which show the compression rate is over 99.9%.
