It is called SERVICE PACK to a set of computer programs consisting of a group of updates that correct and improve operating applications and systems whose support from the seller is still valid. This denomination was popularized by Microsoft when you started packaging groups of patches that updated your Microsoft Windows operating system. In computer science, they are generally referred to as SPX, where X represents the version or revision. For example, SP3 implies that it is the third SP that is done to the product.
