Maintenance is he act and result of maintaining or maintaining. East verb (to maintain) has several uses: it can refer to sustaining or keeping something, to continue with what is in progress or to meet material needs.
The concept is often used with reference to preventive and repair procedures that are carried out in buildings and machines so that they are in working keep running. Maintenance involves the preservation and restoration of the elements.
It is called Preventive Maintenance to the one who is oriented to keep the facilities and mechanisms. For this, reviews are carried out on equipment that is in operation. The purpose of preventive maintenance is to minimize the risk of failure: this can be achieved by replacing parts that are worn, for example.
The Corrective maintenance, meanwhile, it is necessary when a team does not work or does it incorrectly. In this context, the tasks aim to detect the problem and fix it through a repair or fix.
Take the case of a computer (a computer). Preventive maintenance consists of checking hardware and software while the computer is operating normally. This includes everything from cleaning the fans to removing temporary system files. If the computer begins to fail (it works slowly or restarts itself, to name two possibilities), it will be essential to carry out corrective maintenance to search for and eliminate viruses, change hardware elements that are damaged, etc.
In short, preventive maintenance must be done periodically so that corrective maintenance is not unavoidable, which is usually more expensive and complex.
To carry out preventive maintenance on a device such as a computer, smartphone or tablet, we must think in a practical way and adopt an attitude when using it that promotes good functioning. We cannot expect our devices to respond optimally if we treat them carelessly.
As mentioned in a previous paragraph, deleting temporary files is a practice that should become a custom for any PC and mobile device user. Operating systems accumulate this data each time they perform tasks such as installing a program or downloading updates; In addition, in the case of the Internet, there are temporary files that speed up the load of the pages from the second time we visit them.
Since most temporary files are not used more than once, leaving them on disk indefinitely is a waste of resources. Something similar happens with the downloads that the user himself executes: when he intends to install a program or add functionality to the OS and you get an executable file directly from the Internet, allocate space in a directory for storage. Once you use it, it is best to delete it, as it will likely become obsolete in no time.
With regard to material maintenance, the fundamental point is the cleaning of the devices. In the case of phones and tablets, it is not possible to open them, but you can remove dust and stains from the screen and the case. The computer is a very different case: we must open it periodically, uninstall each component (graphics card, hard drives, fans, etc.) and do a thorough cleaning to remove the dirt that could prevent the correct refrigeration.
Another point to take into account in preventive maintenance is the temperature of the environment and exposure to smoke: no matter how much we optimize disk space and clean devices, if we do not use them in a conducive environment our efforts may be in vain.
