A system administrator is an IT professional whose main task is to ensure the proper functioning of a particular computer resource. This resource can be a local network, a website, a server, or a specific piece of software.
His or her responsibilities include managing settings for optimal performance, providing technical support, and establishing the necessary security measures to protect the integrity and reliability of the system entrusted to them.
To successfully perform these tasks, an administrator is granted advanced access rights and privileges. These privileges allow them to make changes that are usually not available to standard users of the system.
It is worth noting that despite the wide range of powers, the administrator must use them with special responsibility, adhering to the principles of security and system efficiency.
