Question 1

What is the main advantage of Test-Driven Development (TDD)?

Accepted Answer

It ensures tests are written before code, clarifying requirements and catching regressions early

Answer

TDD's red-green-refactor cycle forces developers to define expected behavior before implementation, leading to better-designed, well-tested code.

Question 2

What is the difference between a process and a thread in software execution?

Accepted Answer

A process is an independent program with its own memory; a thread is a lightweight unit of execution within a process sharing its memory

Answer

Processes have separate memory spaces and resources, while threads within the same process share memory, making threads lighter but requiring synchronization.

Question 3

In software engineering, what does 'cohesion' refer to?

Accepted Answer

The degree to which elements within a single module are functionally related

Answer

High cohesion means that a module's responsibilities are strongly related and focused, making it easier to understand and maintain.

Question 4

What is a 'deadlock' in concurrent programming?

Accepted Answer

A state where two or more threads are each waiting for resources held by the other, preventing any from proceeding

Answer

Deadlock occurs when processes are stuck in a circular wait, each holding a resource the other needs, so none can make progress.

Question 5

What is the purpose of an abstract class in object-oriented programming?

Accepted Answer

To define a common interface and partial implementation that subclasses must complete

Answer

An abstract class provides a template with some implemented behavior and declares abstract methods that concrete subclasses are required to implement.
