Perfect mam. You taught us with a lot of examples to practically understand it. don't give heed to others, they always wanted graphic-based teaching, but fail to notice the gems
how is the index being compared..eg if i want to search roll no record from a students table where there are another 10 blocks in db,how is the primary key of students table being compared to index ?
They are typically stored in a B-Tree or B+ Tree data structure, which has all its elements ordered while making search efficient. On disk they do not need to be physically together but they can. @@advaithrvasistha44

You can't order the elements in Hash Table, this method is used to search in ordered arrays
@@coffeedude so the rows are stored sequentially?
