What happens when files are zipped?
“Zipping” allows computer files to be compressed to a smaller size–sometimes much smaller–so they can be transmitted more quickly. Essentially, it works by identifying frequently used pieces of code.RedundanciesComputer files are full of redundancies–long strings of bytes that are used over and over again.ReplacementCompression programs identify redundancies in a file and replace them with a marker that stands in for the full piece of code.
