Discussion
Two basic constructs to link one piece of data with another piece of data: sequential storage and pointers.
Answer: A
Correct answer: True
Every physical structure reduces to one of the two. Sequential storage links records by placing them next to each other, so the next record is found by continuing to read. Pointers link them by holding an address, so the next record can be anywhere. Indexes, hashing and chains are all built from these two ideas.
