Answer:

The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.

The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.

Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.

Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression

Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression

Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method

Example of type of data for Lossless compression: Text

Example of type of data for Lossy compression: Audio

Answer:

Lossless retains the file size while lossy algorithm discards excess files size or parts.

Explanation:

Compression algorithms are algorithms used to minimise the file size of a large file format. It is handy for maximising available disk space and reduce upload and download time of these files. Lossless and lossy are two types of compression algorithms.

Lossless algorithm is used to compress a file, but yet retains the structure of the original file or data. It is used where an identical file from the original is favourable and is used in archives.

Lossy is the opposite of lossless because it discards excess parts of a file. It is used in compressing audio files like MP3.

The final step in the object-oriented design (OOD) process consists of developing the <u>package diagrams.</u>

<u></u>

In the field of Computer studies, object-oriented design (OOD) can be described as a design method in which a proper system of interacting objects is planned for making a computing system or software.

The final step of an object-oriented design (OOD) involves the development of package diagrams. Package diagrams are structures or diagrams that are used for representing the model elements. The model elements are shown as packages in this kind of diagram.

Package diagrams are the final step of an object-oriented design process because they help to provide a visual idea of the overall proposed design.

1. Extract title Write a function extract_title that takes one parameter, the filename of a GenBank formatted file, and returns
trapecia [35]

Answer:

def extract_title(file):

   import re

   a =''

   with open(file,'r') as file:

       for line in file:

           a += line

       m = re.search("^(TITLE)(.*?)(JOURNAL)", a, re.M + re.S)

       print(m.groups()[1])

extract_title('new.txt')

Explanation:

The programming language used is python 3.

The function is first defined and the regular expression module is imported.

A variable is initialized to an empty string that will hold the content of the GenBank formatted file.

The file is opened and every line in the file is assigned to the string variable. The WITH statement allows files to be closed automatically.

Regular expression is used to capture all the files between TITLE and JOURNAL in a group.

The group is printed and the function is called.

I have attached a picture of the code in action.
