Frequently Asked Questions (FAQs)

Q1. What is decomposition in computer science?

Ans. Decomposition in computer science means breaking a big, complicated problem or system into smaller, easier-to-handle pieces. This approach helps you understand, build, and test each part on its own. It’s an important idea in problem-solving, especially in programming and software development, because it lets developers concentrate on one task at a time without getting overwhelmed by the whole system.

Q2. What is abstraction in computer science?

Ans. Abstraction means hiding the unnecessary details so you can focus on what really matters. In computer science, it makes complicated systems easier to understand by showing only the important parts. For example, when you use a mobile app, you see a simple interface, while all the complex code and background work stay hidden; that’s abstraction at work.

Q3. What is a variable in computer science?

Ans. A variable in computer science is a named storage location in a program that holds a value, which can change during the execution of the program. Think of it like a container that stores data, such as numbers, text, or more complex data types. Variables are fundamental to programming because they allow developers to write flexible, reusable, and dynamic code.
