SNMP
SNMP (Simple Network Management Protocol) is an application-layer protocol used for managing and monitoring network devices such as routers, switches, servers, and printers. It enables network administrators to collect information, configure parameters, and receive notifications about network performance and faults. SNMP operates over UDP and uses a client-server model with agents on devices and managers for centralized control.
Developers should learn SNMP when working on network management systems, IoT device monitoring, or infrastructure automation, as it provides a standardized way to query and control networked hardware. It is essential for roles involving network operations, system administration, or developing tools for performance monitoring and fault detection in enterprise or telecom environments.
