JPG's not too bad but GIF is terribly lossy

File-based systems are low cost and do not need external storage or somebody that is extremely knowledgeable in technology. Disadvantages include data duplication, lack of flexibility, and a lack of security.

There are a ton. Most things that use wavelets to encode the data fall into this category. Often the same file format and "extension" can have multiple actual encoding mechanisms on the inside, so it might sometimes have lossy compression and sometimes not. Examples of file formats with lossy compression include mp3,jpeg and mpeg. Container formats like avi, and wma sometimes do and sometimes don't.
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
