Software Development Kit. It is a collection of tools, libraries, documentation, and sample code that developers use to create software applications for specific platforms, frameworks, or hardware.

Key Components of an SDK:

• Compiler/Debugger: Tools to write and test code.
• APIs (Application Programming Interfaces): Predefined functions for interacting with the platform or service.
• Documentation: Guides, manuals, and reference materials for developers.
• Sample Code: Example projects to demonstrate how to use the SDK.
• Libraries/Frameworks: Pre-built code modules for common tasks.
• Emulators/Simulators: Tools for testing applications without physical hardware (e.g., Android Emulator).

Common Examples:

• Android SDK: For building Android apps.
• iOS SDK: For building iOS apps.
• Unity SDK: For game development.

AWS SDK: For integrating with Amazon Web Services.
