Similarly, how does file compression software work?

Compression is the method computers use to make files smaller by reducing the number of bits (1's and 0's) used to store the information. Lossy compression makes the file smaller by getting rid of bits and hoping you won't notice. In images this can be done by looking at pixels that next to each other.

One may also ask, why do you need data compression? Compression frees up drive space and closes up memory gaps, reducing the time needed to locate data on a drive. Speed up backups. Compressed files transfer faster and use less bandwidth than their uncompressed counterparts. A good compression strategy thus supports an effective backup plan.

In respect to this, how does WinZip compression work?

Once you download the file, your computer uses a program such as WinZip or Stuffit to expand the file back to its original size. Instead of listing a piece of information over and over again, a file-compression program lists that information once and then refers back to it whenever it appears in the original program.

Does compressing a file lose quality?

Zip format definitely does not reduce quality. There are two types of compression - lossless compression and lossy compression. However, a zip file can increase the chances of loss of data: This is because a few bits of errors in a zip file can prevent the entire Zipped folder from being unzipped.
