File Compression Software aka Zip Software takes large files and compresses them into smaller, easier and faster to store and transfer files.  This saves not only time, but also bandwidth and storage space. There are at least two ways to accomplish this compression task.

One method is termed lossless compression.  This name is because no data is lost and the files can be recreated completely.  This is a complicated method of gathering repeated information and using a dictionary to create ‘smaller’ symbols.

Another method is called ‘Lossy’ compression.  This method eliminates bits of information, making the file smaller.  This method works well on photographs and large-sized bitmap pictures.
