First Come First Serve

First Come First Serve:

This algorithm performs requests in the same order asked by the system. Let's take an example where the queue has the following requests with cylinder numbers as follows:

98, 183, 37, 122, 14, 124, 65, 67

Assume the head is initially at cylinder 56. The head moves in the given order in the queue i.e., 56→98→183→...→67.
