Learn how to do it, what types of utilities to use, and where to find them. When you download a file from the Internet, more often than not the file is compressed. Compressed files save time on downloading and take up less space on the server. But the Internet is not the only place compression is used.
Many computer users compress their files so that they have more room on disks.
Lossy compression actually loses data as part of the compression process. While this type of compression would have disastrous effects on computer programs, text, and data files, lossy compression is commonly used with pictures. Because much of the data that goes into a picture may not make a difference in regards to how we see a picture on the screen, lossy compression works fairly well when compressing photos and graphics. JPEG is a well-known type of lossy compression. Lossless compression makes files smaller without losing data.
