Perfect explanation. The index converts a linear search O(n) to a binary search O(logn).

[@myelibrary]

This is a fantastic explanation of how MySQL indexes work , the key is how binary indexes work- great job

[@growtogether8014]

This is exactly what I was searching for. So, in layman terms it creates a new table with column on which index has been created and memory pointer locations of each associated record. Then it sorts it and applies the Binary search algorithm to search the requested column value and there by fetches the associated pointer location, which in turn takes us directly to that memory location and presents the record to user.
