I was going through the comparator topic and realised that it merely compares the input and the reference voltage. Is it necessary to use resistors along with the inputs in such a circuit? I cannot find any effect of these resistors on the circuit or the output yet it seems to be an elementary addition everywhere.

How do You propose to obtain a "Reference-Voltage" ?

A "fixed" Reference-Voltage is not a prerequisite, both can be variable.
