Patch and the things to learn
Security patch software has two primary purposes: to address vulnerability issues and to improve program performance. A security patch's primary function is to neutralize the threat posed by new malware. If the malware is complicated, so will be the security patch. The more complex computer networks often, and quite unintentionally, contain security holes that are ripe for exploitation by hackers, opening the system to attack. In the "old days," a computer operator used to receive his security patch via paper tape or punch card.
