What is preventive maintenance?Preventive maintenance is one that is carried out in advance in order to prevent the emergence of breakdowns in appliances, electronic equipment, motor vehicles, heavy machinery, and so on.
Some preventive maintenance actions are : adjustments, cleaning, analysis, lubrication, calibration, repair, parts changes, among others. In the area of computer science, preventive maintenance consists of reviewing the software and hardware of the PC or computer, which allows the user to have a reliable equipment to exchange information at maximum speed with respect to the configuration of the system.
In reference to the above, in the area of information technology, preventive maintenance and updated maintenance must be differentiated since the latter is produced at the request of the user in order to improve the system by updating the technological programs contained in the computer.
Likewise, the cost of preventive maintenance is calculated through the extra time, time of the assistants and labor, as well as, the inventory of spare parts, for example: in cars, filter change, lubrication, etc., each spare part has a different cost.
Preventive maintenance is carried out periodically. Similarly, preventive maintenance aims to detect failures that may lead to malfunction of the object in maintenance and, thus avoiding high repair costs and decreases the likelihood of unforeseen stoppages, also allows a longer duration of the equipment and facilities and greater security for the workers, especially in the case of those employees who work in industries with large machinery.
Preventive maintenance is divided into: scheduled maintenance, predictive maintenance and maintenance of opportunity. Scheduled maintenance is characterized by being performed in a certain time or mileage, as is the case of cars; The predictive maintenance is carried out through a follow-up that determines the moment in which the referred maintenance must be carried out and, the maintenance of opportunity as indicated by its name is made taking advantage of the periods in which the object is not used.
On the other hand, the person in charge of carrying out the different types of maintenance in machinery, equipment, vehicles, among others, are called technicians are individuals with skills or abilities in relation to this area.

Corrective maintenanceCorrective maintenance as indicated by its name is characterized by correcting or repairing defects in equipment and machinery. However, when corrective maintenance is performed immediately on the equipment, it can be called contingent corrective maintenance , whereas when the day is scheduled to check and correct the equipment failure, it is known as programmable corrective maintenance .
The corrective maintenance is characterized by the arrangement of the machine or equipment by means of the change of the damaged piece by another making the system work properly again.
