Best answer 1 votes 1 votes Indexing refers to finding out the location where a specific block or line can be present in the cache. We require tags because caching is a many to one mapping procedure and hence more than one line can be cached to the same location. To check if the required block is present at a given index we compare the tags. Note: There are different type of caches like Physically indexed-Physically tagged and Vitually indexed-Physically Tagged caches. But that's a different question altogether.
