The RPC portmapper (portmap(8)) is a server that converts RPC program numbers into TCP/IP (or UDP/IP) protocol port numbers. It must be running in order to make RPC calls (which is what the NIS/NIS+ client software does) to RPC servers (like a NIS or NIS+ server) on that machine.

How does rpcbind convert RPC program numbers to Universal addresses?

The rpcbind utility is a server that converts RPC program numbers into universal addresses. It must be running on the host to be able to make RPC calls on a server on that machine. When an RPC service is started, it tells rpcbind the address at which it is listening, and the RPC program numbers it is prepared to serve.
