In SNMP, messages are exchanged between the SNMP server and a remote device (for our discussion probably a router or a switch). The difference between a poll and a trap is which device initiates the communication. An SNMP poll is initiated by the server and the router or switch responds to the server. An SNMP trap is initiated by the router or switch when it has information to send (usually some event happened) and does not want to wait for the server to ask for information.

A trap is a notification that the device (router, switch, printer...) sends to the monitoring software (Manager/NMS) when some problem occurs. The polling process is when the monitoring software asks the device for his status/health, usually every 5 minutes.
