Add your answer
Q2. Draw and explain the structure of a cmos
Ans. 
A CMOS (Complementary Metal-Oxide-Semiconductor) is a type of integrated circuit technology that uses both NMOS and PMOS transistors.
• CMOS is widely used in digital logic circuits due to its low power consumption.

• It consists of a combination of NMOS (n-type) and PMOS (p-type) transistors.

• The NMOS transistors are used for logic 0 and the PMOS transistors for logic 1.

• The transistors are connected in a complementary manner...read more

Q2. What is the principle of OOPS
Ans. 
OOPS stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPS focuses on the use of classes and objects to organize code

• Encapsulation: bundling data and methods that operate on the data into a single unit (class)

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: the ability for objects of differ...read more

Q1. What is the OOPS
Ans. 
OOPS stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPS focuses on creating objects that interact with each other to solve problems

• It involves concepts like classes, objects, inheritance, polymorphism, and encapsulation

• Example: In a banking system, you can have classes like Account, Customer, and Transaction, each with their own pro
