It provides a method to have a receive window larger than permitted by the original TCP specification (16 bits, or 64K). You can "scale" the 16 bit value by some power of 2.

what is the receive window?

You might start here:

http://en.wikipedia.org/wiki/TCP_tuning, where RWIN (TCP receive window) is mentioned. Much more can be found if you use an Internet search engine.
