What is the difference between a ring shift counter and a Johnson shif

1.	What is the difference between a ring shift counter and a Johnson shift counter?(a) There is no difference(b) A ring is faster(c) The feedback is reversed(d) The Johnson is fasterI got this question in semester exam.The doubt is from Universal Shift Registers in section Registers of Digital Circuits
Answer» CORRECT choice is (c) The FEEDBACK is reversed Best EXPLANATION: A ring counter is a shift register (a CASCADE connection of flip-flops) with the output of the last ONE connected to the input of the first, that is, in a ring. Whereas, a Johnson counter (or switchtail ring counter, twisted-ring counter, walking-ring counter, or Moebius counter) is a modified ring counter, where the output from the last stage is inverted and fed back as input to the first stage.
