The Producer$-$Consumer Problem

$(10$ Marks$)$

The Producer$/$Consumer pattern is one of the most widely used patterns in multiprocess synchronization problem. The project is divided into a theoretical part,

discussing the pattern concept and how it works, and a practical part that simulates

an environment with a problem to be solved using The Producer$/$Consumer

mechanism.

The theoretical part is to cover some aspects of the Producer$/$Consumer

pattern:

$$ Concept$/$Idea

$$ Problem

$$ Use in operating systems

$$ Semaphores as a solution

The practical part is to simulate the print jobs of a printer, one job at a

time: either from Producer or Consumer.

$$ A shared object called a Buffer.

$$ Set$1$ of threads, producers, put data in the buffer with $(1)/(2)$ second

delay.

$$ Set$2$ of threads, consumers, read data from the buffer with one

second delay.
