The maintenance of a computer system is intended to ensure that the equipment is operating as long as possible and, during that time , to operate as efficiently and with maximum safety for personnel using them. The maintenance of a computer system involves both software and hardware maintenance .
Tecnico informatico
To perform this maintenance in Spain and in most European countries there are a number of specific techniques . In Spain these techniques are collected in a methodology called METRIC .
A computer system uses computers to store data, process and make them available to anyone who considers appropriate. A system can be as simple as : a person has a computer and introduces such basic data , such as daily sales of a small business , there is an entry for each sale and she declares the item sold , such as a loaf of bread, the quantity of items sold, for example four and the selling price per unit , for example .15 euros. Each entry is stored as a record in a file on disk . At the end of the day you can get a report of sales and trends. The user can use this information to store management or planning advertising campaigns. Usually a company has more than one computer , eg, one for management and one for sales accounting and associated processes. However most of the systems are more complex.
