Lossy compression algorithms are techniques that reduce file size by discarding the less important information. Nobody likes losing information, but some types of files are so large that …

Lossy compression algorithms reduce the size of files by discarding the less important information in a file, which can significantly reduce file size but also affect file quality.

Check your understanding of lossy and lossless compression techniques, in this set of free practice questions designed for AP Computer Science Principles students.

Lossless data compression Reduce the size of the file, but don't lose any of it!

Images are all around us, from application icons to animated GIFs to photos. Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the …
