Class subject: Compression and Archives.

Archive formats are used for backups, mobility, and archiving data. Many archive formats compress the data to consume less storage space and result in quicker transfer times as the same data is represented by fewer bytes. Another benefit is that files are combined into one archive file which has less overhead for managing or transferring. There are numerous compression algorithms available to losslessly compress archived data and some algorithms work better (smaller archive or faster compression) with particular data types. Archive formats are also used by most operating systems to package software for easier distribution and installation than binary executables. An archive file is a file that is composed of one or more computer files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption. What we learn from this game is that files which have many repeated words or phrases have better compression and that picture files can not have good compression. And that we can place a lot of files in a folder and archive it to make a single file.
