This subject is a sub-topic in Computer Science and is related to how computers process tasks using Modern Processing Architectures. Modern Processor Architecture is an offshoot of computer architecture.
<h3>
What is Modern Processing Architecture?</h3>
Please note that the information is incomplete hence the general answer. The complete question should provide figures for items 1 to 3.
Modern Processor Architecture is the name given to computer processors with highly advanced capabilities.
In simple language, processors with modern architectures are those that have been built with the ability to complete many instructions or tasks at the same time.
It can also perform or execute these instructions in random order. When a processor is able to do this, it is called Asynchronous performance.

Answer:
Explanation:
Following are the Semaphores:
Customers: Counts waiting customers;
Barbers: Number of idle barbers (0 or 1)
mutex: Used for mutual exclusion.
Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves
Shared data variable:
count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.
// shared data
semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;
int count_cust= 0;
void barber() {
while(true) { //shop is always open
wait(customers); //sleep when there are no waiting customers
wait(mutex); //mutex for accessing customers1
count_cust= count_cust-1; //customer left
signal(barbers);
signal(mutex);
cut_hair();
}
}
void customer() {
wait(mutex); //mutex for accessing count_cust
if (count_cust< n) {
count_cust= count_cust+1; //new customer
signal(customers); signal(mutex);
wait(barbers); //wait for available barbers get_haircut();
}
else { //do nothing (leave) when all chairs are used. signal(mutex);
}
}
cut_hair(){ waiting(cutting);
}
get_haircut(){
get hair cut for some time; signal(cutting);
}
