Become A System Administrator

System Administrator – Roles and Responsibilities

The roles and responsibilities of a system administrator can vary widely from one organization to another. Here are the four types of system administrators based on their roles and responsibilities:

Network Administrators

Network administrators manage the entire network infrastructure of an organization. They design and install computer systems, routers, switches, local area networks (LAN), wide area networks (WAN), and intranet systems. They also monitor the systems, provide maintenance and troubleshoot any problems when they arise.

Database Administrators

Database administrators (DBA) set up and maintain databases used in an organization. They may also be required to integrate data from an old database into a new one or even create a database from scratch. In large organizations, there are specialized DBAs who are only responsible for managing databases. In smaller organizations, the roles of DBAs and server administrators can overlap.

Server/Web Administrators

Server or web administrators specialize in maintaining servers, web services and operating systems of the servers. They monitor the speed of the internet to make sure that everything runs smoothly. They also analyze a website’s traffic patterns and implement changes based on user feedback.

Security Systems Administrators

Security systems administrators monitor and maintain the security systems of an organization. They develop organizational security procedures and also run regular data checkups – setting up, deleting and maintaining user accounts.

In large organizations, all these roles may all be separate positions within one department. In smaller organizations, they may be shared by a few system administrators, or even one single person.
