What are the differences between various compression algorithms?

There are several compression algorithms, each with its strengths and weaknesses. For example, ZIP is widely used for general purposes, while algorithms like LZ77 and LZW are more efficient for specific types of data.

Can you explain how lossless and lossy compression differ?

Sure! Lossless compression retains all original data, allowing for perfect reconstruction, while lossy compression sacrifices some data for higher compression rates, which is often used in images and audio.

Which algorithm is best for compressing images?

For images, JPEG is popular for lossy compression, while PNG is preferred for lossless compression. It depends on whether you need quality or file size.

What about video compression algorithms?

For video, H.264 is widely used for its balance of quality and compression, while newer codecs like H.265 offer better efficiency at the cost of processing power.
