A very brief and wholly inadequate summary:
A process needs to be running on your web server on port 161 listening
for SNMP queries. You send it a request, it sends you back an answer.
The encoding for the data that this process keeps is kept in a structure
called a MIB which stands for Management Information Base. The MIB is
described in a language called ASN.1 (Abstract Syntax Notation) which is
just a way to describe all of the objects which can be queried from a
particular host.
For more detailed information, I suggest one of the many excellent books
describing SNMP such as 'The Simple Book', or one of the 'Internetworking with
TCP/IP' volumes or 'TCP/IP illustrated' volumes, or any of the RFCs
describing SNMP and all of the standardized MIB extentions.
