Software aging is a phenomenon that occurs in all types of software, regardless of who created it or how powerful the software was when it was purchased. Software aging is the gradual degradation of encoding where fragmentation begins to show itself, leading to slower performance and reduced output. Software rejuvenation aims to fix aging errors, but offers only a limited solution to the problem. Continuous software updates also aggravate the effects of aging and the original coding becomes deformed. Most users find it easier and less time-consuming to purchase new software instead of trying to keep outdated software.
The software used for the first time is new and no degrading code has been introduced, nor has its information been fragmented. This means that the program can run quickly, without any problems. As software ages, the operating system will be able to put fewer resources into the program. With fewer resources and degrading code, software starts causing lags or may shut down automatically.
Updates, while seemingly good, can have devastating effects on aging software. An update introduces new code. This new code can help the effects, or visibility, of fragmented code. The update also introduces more code, which increases the size of the program. This means that even more resources are required to produce the same output as before the update was added.
Software rejuvenation has been employed to correct the harmful effects of software aging. There are many types of software rejuvenation techniques but overall, they aim to ease fragmentation and return the software to its original coding. Software rejuvenation offers a limited solution because it cannot fix all errors and is best used on software that is showing low to average signs of aging.
Years after you get a piece of software, the effects of aging software will become inevitable. The amount of time isn’t set, because it depends on how well the program is done, but usually 10 years is the upper range when the effects of aging make the program nearly unusable. Software rejuvenation may fix some of the bugs when the software gets to this point, but the effects of aging will still make the program difficult to use.
When the effects of aging software are unavoidable, most users choose to purchase new software. New software won’t need as much maintenance until later in its life and will be able to produce better output than older software. Purchasing newer software, especially for businesses, frees up human resources to work on other tasks or projects.
