Important 2 Marks Questions from Previous Year Question Papers
The important 2 marks questions provided here are collected from the last 6 years Tamil Nadu State Board public examination question papers and important school examinations.
📌 Note for Students
The number mentioned next to each question indicates how many times the question has been repeated in previous public examinations and school examinations. Questions with higher repetition counts are more important for board exam preparation.
1.What is a subroutine? (5)
- Subroutines are small sections of code that are used to perform a particular task that can be used repeatedly.
- Subroutines are the basic building blocks of computer programs
2.Differentiate interface and implementation.(4)
| Interface | Implementation |
|---|---|
| Interface just defines what an object can do, but won’t actually do it | Implementation carries out the instructions defined in the interface |
3.Define function with respect to programming language? (2)
A function is a unit of code that is often defined within a greater code structure. Specifically, a function contains a set of code that works on many kinds of inputs, like variables, expressions and produces a concrete output.
Write the inference you get from X:=(78) (2)
- X:=(78) has an expression. But, (78) is not an expression.
- (78) is a function definition.
- Definitions(78) bind values to names (X).
