Final answer:
An SNMP agent is the component that runs on managed devices, collecting management information for SNMP managers.
Step-by-step explanation:
The software component that runs on a managed device when you deploy Simple Network Management Protocol (SNMP) is known as an SNMP agent. The SNMP agent is responsible for gathering information from the device and making that information available to the SNMP manager, which usually runs on a Network Management System (NMS). The collected data is organized in a Management Information Base (MIB), which is a database used for managing the entities in a network device.
