File Compression
I think answer is File Compression
Compression ratio in engineering can be calculated by dividing the total volume of a system before compression by the total volume after compression. In computing, file compression ratios are calculated by comparing the original file size to the compressed file size.
There are many pieces of software that can test the quality of a file compression software. The file compression software itself can give a percentage of compression, as well as a verification of whether it is compressed properly. One can also check the 'checksum' of the file.
The unknown compression method used in this file is not specified or identified.
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.
File compression
decrement in file size.........
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.

Which compression type using in BMP image file? The BMP image file normally doesn't use any compression at all. This is why usually they are large files and are not used on the web.
