Simple Network Management Protocol (SNMP) allows network devices to communicate information about their status and configuration to network management systems. Network management systems use SNMP to monitor devices on the network, detect issues, and control devices. They observe the network and can perform tasks like troubleshooting, monitoring server and equipment uptime, and managing traffic, security, and performance. Management Information Bases (MIBs) contain information about networking devices that is accessible to network management systems using SNMP to monitor device conditions from outside. Uninterruptible power supplies (UPS) have backup batteries and generators to provide power to computers during blackouts, allowing users to safely shut down systems in an outage.
