Question

In the text box below, answer the following two questions: What is the compression rate? The compression rate says by how much the text was compressed from the original as a percentage. Don't forget that the compressed version of the text is the compressed text size + dictionary size. (see note below) Is this a "good" compression rate? Why or why not?

Answer 1

The answer to the two questions can be given as:

A) compression rate:

In the compression rate, we compress the original size of the data in the percentage. In the compression rate, we do not forget its compress version of the file.

B) Is the compression rate good? Why or why not?

Compression information is a heuristic difficulty. It is tough to answer the correct compression rate that is good or bad. If you feel convinced by ~ 26% of compression, then it is a good rate. It above frees up 26% space for you so that you can put extra information without missing information. That's why it is good.

Explanation:

The above answer can be explain by the following example that can be given as:

Suppose that compressed text size = 20 bytes and the dictionary size = 30 bytes

compression rate(CR)=compressed text size(CTS)+dictionary size(DS)

CR=CTS+DS

CS=20+30

CS=50.

if original test size = 87 bytes

compression rate as percentage = (50/ 87) * 100 = 57.47%

Space savings(SS)= 100 - compression rate(CR)

SS= 100 -57.47

SS=42.53.

So we can say that the compression rate is good.
