Data compression in computer science

What are examples of data compression?
Compression algorithms are normally used to reduce the size of a file without removing information.
This can increase their entropy and make the files appear more random because all of the possible bytes become more common..
What is compression A level computer science?
A file reduced in size through the application of a compression algorithm, commonly performed to save disk space.
The act of compressing a file makes it unreadable to most programs until the file is uncompressed..
What is compression algorithm in computer science?
Compression is a technique that reduces file size.
Some compression techniques are referred to as lossy, because they cause data to be lost during the compression process.
Other techniques are referred to as lossless, because they allow the original data to be exactly reconstructed from the compressed data..
What is compression computer science?
Data compression is a reduction in the number of bits needed to represent data.
Compressing data can save storage capacity, speed up file transfer and decrease costs for storage hardware and network bandwidth..
