Definition of Information System

Information system is a system that includes a set of tools and methods designed to store, process, search and provide information to an end user or device.

Most of companies in order to achieve the benefits provided by the information system, prefer to have one specialist on staff who can run the OS on the PC, in which case the site on the Ruby on Rails platform should be administered, and it is also desirable that he well versed in the administration of Windows Server and FreeBSD, and, of course, he should be able to refill the printer.

His direct responsibilities include connecting terminal equipment of an office or enterprise with pulling a twisted pair cable, and when the accountant does not have mail, the system administrator must come and fix the problem. And we will not even touch upon such trifles as monitoring and paperwork for the purchase of software and hardware.
