In short the patch is the difference between the previous version and upgraded version of a software. Similarly Apache patches are designed to improve the performance of Apache within different areas. Official Patches released by Apache can be treated as upgraded versions of Apache. If one has the Apache source product installed then the patches will be installed or updated automatically, otherwise the files will be there in the actual patch and one can find them under any of the ‘reloc’ directories. Being an open source a person can develop a patch as per his requirements and can also share it with others. But though the patches are developed with the purpose of fixing problems and bugs, a wrongly developed patch can affect inversely with the performance of Apache. Few of the developers also have provided the patch management softwares in the market to manage the patches with the ease. Even few of such softwares can update multiple computers at the same time withing multiple networks.
