Week 10: Counters and RSS


A web counter counts how many times a website or certain page has been viewed. Most counters count the number of unique hits a page gets while others count how many times a page was viewed even if the same person viewed it repeatedly.

A Johnson counter, on the other hand, (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. A pattern of bits equal in length to twice the length of the shift register thus circulates indefinitely. What, you ask, does this have to do with Web Counters? Not a damn thing, but it looked funny at the time. Johnson counter...come on its funny.

Hey there Rick,
I just have a quick question and was hoping u could help. how do i know if my counter tracks original hits rather than every hit?

Cheers, Anna (from the second group)
