Contrast the performance of the three techniques for allocating disk blocks (contiguous, linked, and indexed) for both sequential and random file access.

The three techniques are given below.

Explanation:

Contiguous

Sequential - Plays quite well, since the document is located or stored adjacent. Random - Consider it wouldn't fit properly, but perhaps the hero of course insists differently.

Linked

Sequential - Functions all right if you navigate the ties from each block to block. Random - It will be bad because you might need to cross the connections.

Indexed

Sequential - Functions well as accessibility sequentially essentially includes navigating each index in sequential order. Random - Works perfectly fine, because the index or classification from either the index blocks are simple to evaluate.
