Data compression is the compacting of data by lowering the number of bits that are stored or transmitted. Consequently, the compressed information will take less disk space than the initial one, so extra content could be stored on the same amount of space. There are many different compression algorithms that function in different ways and with some of them just the redundant bits are deleted, which means that once the data is uncompressed, there is no loss of quality. Others delete unnecessary bits, but uncompressing the data later will result in lower quality in comparison with the original. Compressing and uncompressing content consumes a large amount of system resources, and in particular CPU processing time, so any web hosting platform which uses compression in real time should have ample power to support that attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the actual code.
