System administrators—also known as sysadmins—are information technology (IT) professionals who make sure an organization's computer systems are functioning and meet the needs of the organization. Sysadmins support, troubleshoot, and maintain computer servers and networks.
System administration functions include user management, system monitoring, backup and recovery, and access control. System monitoring, backup, and recovery functions are typically integrated into an organization-wide application. User management functions include user creation and assigning roles to users.
