Detailed explanation-1: -How compression works. Compression is performed by a program that uses a formula or algorithm to determine how to shrink the size of the data. For instance, an algorithm may represent a string of bits–or 0s and 1s–with a smaller string of 0s and 1s by using a dictionary for the conversion between them.
Detailed explanation-2: -A) To compress something by pressing it very hardly (B) To minimize the time taken for a file to be downloaded (C) To reduce the size of data to save space (D) To convert one file to another Answer Correct option is C.
Detailed explanation-3: -There are broadly two types of data compression techniques-lossy and lossless. In lossy, the insignificant piece of data is removed to reduce the size, while in lossless compression, the data is transformed through encoding, and its size is reduced.
