Question

The FIFO algorithm :

a) first executes the job that came in last in the queue
b) first executes the job that came in first in the queue
c) first executes the job that needs minimal processor
d) first executes the job that has maximum processor needs

Answer 1

The FIFO algorithm first executes the job that came in first in the queue, similar to a first-come, first-served approach in a supermarket queue.

Step-by-step explanation:

The FIFO (First-In, First-Out) algorithm is used for scheduling jobs in computing environments. The correct option from the ones provided is that the FIFO algorithm first executes the job that came in first in the queue.

This is analogous to people queueing in a supermarket; the first person to join the queue is the first to be served. FIFO is one of the simplest scheduling algorithms and is used in various computing systems, including operating systems and queue management.
