FCFS (FIRST COME FIRST SERVE):

⮚ In this scheduling algorithm, a person
is served according to the queue manner.

⮚ The person who arrives first in the
queue first buys the ticket and then the next
one.

⮚ This will continue until the last person in the
queue purchases the ticket.

⮚ Using this algorithm, the CPU process works in a
similar manner.

SEMAPHORES:

⮚ In computer science, a semaphore is a variable
or abstract data type used to control access to a
common resource by multiple processes in
concurrent system such as a
multitasking operating system.

⮚ A semaphore is simply a variable.

⮚ If two persons want to access the system at the
time , deadlock will occur.

⮚ To overcome , this situation semaphores are
used.

⮚ In this mini project , deadlocks are handled by

PRIORITY:

⮚ Priority scheduling is a non-preemptive
algorithm and one of the most

common scheduling algorithms in batch
systems.

⮚ Each process is assigned a priority. Process with
highest priority is to be executed first and so on.⮚ Processes with same priority are executed
on first come first served basis.

⮚ In this project, if user wants to access the page ,
admin have to finish his work

⮚ So admin gets the priority first
