Types of File Compression/Eve Rowe

File compression helps to make big files easier for uploading and downloading without taking out to much space on the hardrive. Also makes files much easier to send to others. The two types of compressions that I ran in to a numerous amount of times while searching the web was lossless compression and lossy compression. Lossless compression sounds better to me because the file size you start out with remains the same after the file is decompressed so you lose no data. Lossy compression is a process that makes the file size smaller and you end up losing data but not to noticible. Lossless compression is better for text files, gif files, and tiff files. Lossy compression is best used for media and jpeg files. The most common program I have run into for file compression and home and at work it winzip.
