A program that performs a specialized task, such as a virus scanner, file compression program, or data backup program, is typically referred to as a "utility software." Utility software is designed to help manage, maintain, or protect computer resources and enhance system performance.
RAR is a form of compression. WinRAR is used to create compressed archives. They are similar to zip files, but take up less space when compressed than a zip file.
The program allows large files to be compressed for either sending via e-mail or transferring to another source (e.g. from desktop computer to laptop). One must have the accompaning unzip program to allow the files to be redistruted to whatever source was chosen
I think answer is File Compression
Files are named in the method: filename.extension When the file is a program, the extension is 'exe' so if a file called 'hello' was a program, it would be called: hello.exe
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.
