Text compression techniques

The task of compression consists of two components, an encoding algorithm that takes a message and generates a “compressed” representation (hopefully with fewer bits), and a decoding algorithm that reconstructs the original message or some approx- imation of it from the compressed representation..

What are the ways of compressing data?

What is the compression technique in data compression? 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._{Jul 22, 2022}.

What is the basic file compression?

To understand the use of file compression tools it is necessary to know what is file compression.
So, file compression is basically when we store one or more files in the form of an archive.
Moreover, the size of these files reduces in this process.
Hence we these files take less storage space on the system..
