Q1. Round Robin Algo Bankers algo Encapsulation Pillars of oops Multithreading
Ans. 
Round Robin and Banker's algorithms are scheduling algorithms used in operating systems. Encapsulation is a concept in OOP. Multithreading allows multiple threads to run concurrently.
• Round Robin algorithm is a CPU scheduling algorithm where each process gets a small unit of CPU time.

• Banker's algorithm is a resource allocation and deadlock avoidance algorithm used in operating systems.

• Encapsulation is the bundling of da...read more

Q2. What is Bankers algorithm
Ans. 
Banker's algorithm is a resource allocation and deadlock avoidance algorithm used in operating systems.
• Used to avoid deadlock in a system by ensuring that resources are allocated safely

• Works by keeping track of available resources and the maximum resources each process can request

• Allocates resources only if the system remains in a safe state

• Example: A system has 3 types of resources A, B, and C. Process P1 can request ...read more

Q3. Define encapsulation
Ans. 
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
• Encapsulation helps in hiding the internal state of an object and restricting access to it.

• It allows for better control over the data by preventing direct access from outside the class.

• Encapsulation also enables data hiding, which protects the data from being modified by external code.

• Example: In a class representing a...read more
