SJF scheduling is approximated by predicting the next CPU burst with an exponential average of the measured lengths of previous CPU bursts.
<h3>What is SJF in operating system?</h3>
SJF is a term that connote Shortest Job First. It is said to be a type of CPU scheduling whose algorithm is linked with each as it is said to process the length of the next CPU burst.
Note that for one to be able to know the time for the next CPU burst to take place, one need to take the SJF into consideration as that is its function.
Hence, SJF scheduling is approximated by predicting the next CPU burst with an exponential average of the measured lengths of previous CPU bursts.
See options below
A) Multilevel queue
B) RR
C) FCFS
D) SJF

The four standard layers of a layered architecture are:
- presentation,
- business,
- persistence,
- database.
<h3>What is a Layered Architecture?</h3>
This refers to the architectural style that is used to show components with similar functions in horizontal layers that have specific roles.
Hence, we can see that no generic info system architecture was attached to the answer, so it would be impossible to create a layered architecture, so a general overview was given about layered architecture.

The error message gives it away "#DIV/0!". A division by zero error has occurred, and and error is displayed because dividing by zero is mathematically impossible.
