Maintenance is the act and the result of maintaining or maintaining . East verb (maintain) has several uses: it can refer to sustaining or conserving something, to continue with what is in execution or to solve material needs.

He concept usually used with reference to preventive and repair procedures that are carried out in buildings and machines so that they are in conditions of keep on running . Maintenance implies the preservation and restoration of the elements.

It is called Preventive Maintenance to one who is oriented to keep the facilities and mechanisms . For this, revisions are carried out on equipment that is in operation. The purpose of preventive maintenance is to minimize the risk of failures: this can be achieved by replacing worn parts, for example.

He Corrective maintenance , meanwhile, it is necessary when a equipment It does not work or does it incorrectly. In this context, the tasks aim to detect the problem and solve it through a repair or correction.

Take the case of a computer (a computer). Preventive maintenance consists of checking the hardware and software while the computer is operating normally. This includes cleaning fans to deleting temporary files from the system. If the computer starts to fail (it works slowly or restarts on its own, to name two possibilities), it will be essential to develop corrective maintenance to find and eliminate viruses, change hardware items 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 the preventive maintenance of a device such as a computer, a smartphone or a tablet, we must think in a practical way and adopt an attitude when using it that promotes good functioning . We cannot pretend that our devices respond optimally if we treat them carelessly.

As mentioned in a previous paragraph, deleting temporary files is a practice that should become the custom of any user of PCs and mobile devices. 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 accelerate the load of the pages from the second time we visited them.

Since most temporary files are not used more than once, leaving them on disk indefinitely represents a waste of resources. Something similar happens with the downloads that the user runs: when he intends to install a program or add functionality to the OS and directly obtains an executable file from the Internet, allocates space in a directory for storage. Once you use it, it is best to delete it, as it will probably become obsolete in a short 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 it is possible to 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 earth that could prevent the correct refrigeration .

Another point to take into account preventive maintenance is the temperature of the environment and exposure to smoke: however much we optimize disk space and clean the devices, if we do not use them in an enabling environment, our effort may be in vain.
