The term data compression describes lowering the number of bits of info that should be stored or transmitted. You can do this with or without the loss of information, so what will be erased in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and the quality will be the same, whereas in the second case the quality shall be worse. There are various compression algorithms that are more effective for various type of data. Compressing and uncompressing data in most cases takes lots of processing time, which means that the server carrying out the action must have ample resources to be able to process your info quick enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is known as LZ4. It can upgrade the performance of any website hosted in a cloud hosting account with us as not only does it compress info more efficiently than algorithms employed by alternative file systems, but it uncompresses data at speeds which are higher than the HDD reading speeds. This can be done by using a lot of CPU processing time, which is not a problem for our platform since it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backup copies more speedily and on reduced disk space, so we can have a couple of daily backups of your databases and files and their generation won't affect the performance of the servers. That way, we can always recover any content that you could have erased by mistake.
