• Threading
• Process scheduling
• File handling

can help debug issues like crashes, performance bottlenecks, and resource conflicts.

Linux, Windows, and macOS are common platforms, and developers working in mobile environments should also understand Android and iOS.

How Critical Is Networking Knowledge for Application Developers?

Today’s applications are rarely standalone. Whether it’s a mobile app, website, or enterprise system, they communicate across networks using protocols like HTTP, FTP, TCP/IP, and HTTPS.

A developer should understand:

• How client-server architecture works
• What DNS, IP addressing, and VPNs are
• How to troubleshoot network-related issues

This knowledge is essential in web development, cloud platforms, and distributed systems.

What Are the Essential Software Testing Techniques Developers Must Know?

Testing is the process of verifying that software meets its intended functionality without errors. Developers should not only write functional code but also test it thoroughly.

Three primary types of testing include:

• Unit Testing: Verifies individual components or functions.
• Integration Testing: Ensures modules interact correctly.
• System Testing: Validates the complete application in a production-like environment.

Knowing testing frameworks like JUnit, NUnit, or PyTest, and understanding test-driven development (TDD) can significantly enhance software reliability.
