Ans. 
OOPS concepts refer to Object-Oriented Programming principles such as inheritance, encapsulation, polymorphism, and abstraction.
• Inheritance: Allows a class to inherit properties and behavior from another class. Example: Parent class 'Animal' and child class 'Dog'.

• Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Class 'Car' with private variables and public methods.

Q1. Explain cache memory
Ans. 
Cache memory is a small, high-speed memory unit located between the CPU and main memory, used to store frequently accessed data and instructions.
• Cache memory is faster than main memory, allowing for quicker access to data.

• It helps improve overall system performance by reducing the time needed to access data.

• There are different levels of cache memory (L1, L2, L3) with varying sizes and speeds.

• Examples of cache memory in

Q3. Explain objects and classes
Ans. 
Objects are instances of classes in object-oriented programming, representing real-world entities with properties and behaviors.
• Objects are instances of classes, which act as blueprints for creating objects.

• Classes define the properties and behaviors of objects.

• Objects can have attributes (properties) and methods (behaviors).

• Example: Class 'Car' defines properties like 'color' and 'model', and methods like 'drive' and ...read more

Q4. Explain Polymorphism
Ans. 
Polymorphism is the ability of a function or method to behave differently based on the object it is called with.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Animal class with methods like eat() can be inherited by classes like Dog and Cat, which can override
