Systems Administration and MaintenanceLesson: Types of Computer Maintenance

Today we will learn about one of the core responsibilities of a systems administrator—computer maintenance. Every organization depends on computers, servers, and networks to perform daily operations. Without proper maintenance, systems become slow, vulnerable to cyber threats, and more likely to experience unexpected failures. A systems administrator is responsible for keeping these systems secure, reliable, and available. In this lesson, we will explore the four major types of maintenance: Preventive, Corrective, Predictive, and Emergency Maintenance. By the end of this discussion, you will understand the purpose of each type, know when to apply them, and recognize their importance in real-world IT environments.
