14 Best Free and Open Source Linux Compression Tools

Data compression is the process of storing data in a format that uses less space than the original representation would use. Compressing data can be very useful particularly in the field of communications as it enables devices to transmit or store data in fewer bits. Besides reducing transmission bandwidth, compression increases the amount of information that can be stored on a hard disk drive or other storage device. There are two main types of compression. Lossy compression is a data encoding method which reduces a file by discarding certain information. When the file is uncompressed, not all of the original information will be recovered. Lossy compression is typically used to compress video, audio and images, as well as internet telephony. The fact that information is lost during compression will often be unnoticeable to most users. Lossy compression techniques are used in all DVDs, Blu-ray discs, and most multimedia available on the internet. Read more

However, I didn't want the clutter of a desktop or tower case and all the associated cabling. I briefly considered a Mac Mini but didn't want to surrender to a proprietary interface. I really wanted a Linux desktop with power, portability, and a small footprint. I considered System76's Meerkat but instead opted to build my own computer using an Intel Next Unit of Computing (NUC). Intel created the NUC as a very small, barebones computer system with a number of options. It's more powerful and more modular than something like a Raspberry Pi, but it's smaller than even a microATX sized PC tower. Read more
