The term data compression means lowering the number of bits of information which needs to be stored or transmitted. This can be achieved with or without the loss of information, so what will be removed at the time of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality will be the same, whereas in the second case the quality will be worse. You will find various compression algorithms that are more efficient for different sort of info. Compressing and uncompressing data usually takes plenty of processing time, which means that the server performing the action must have sufficient resources to be able to process the data fast enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code instead of storing the actual 1s and 0s.
Data Compression in Shared Web Hosting
The cloud internet hosting platform where your shared web hosting account will be made uses the outstanding ZFS file system. The LZ4 compression method that the aforementioned employs is better in numerous aspects, and not only does it compress information better than any compression method that other file systems use, but it is also a lot quicker. The benefits can be significant particularly on compressible content such as website files. Even though it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk drive, so the performance of each and every Internet site hosted on our servers will be upgraded. The better and quicker compression rates also allow us to make numerous daily backups of the whole content in each and every Internet hosting account, so if you delete something by accident, the last back-up copy that we have will not be more than a few hours old. This is possible because the backups take much less space and their generation is fast enough, to not influence the performance of the servers.
