Is it a fixie or singlespeed?

Explain me different cranksets and terms(maybe relate to fixie)?

• I ride a fixie and i notice 1/8" x 46T and other ones like 48t, 1/6' and other type of ratio's, i dont really understand and im going to buy a new crankset for my fixie here's a link to the one im trying to go for: http://www.iminusd.bigcartel.com/product/id144 they give you description but I dont understand much,only the 165mm length because most fixie are that length. thank you.
