System administration is the process of managing and maintaining computer systems and networks. It involves tasks such as installing software, configuring hardware, and ensuring that systems run smoothly. System administrators, often referred to as sysadmins, are responsible for troubleshooting issues, applying security updates, and monitoring system performance. In addition to technical skills, system administration requires good organizational and communication abilities. Sysadmins work to ensure that users have access to the resources they need while protecting sensitive data. They may also create backup plans and disaster recovery strategies to safeguard against data loss and system failures.
