What are the benefits of debugging?
Debugging has many benefits such as: It reports an error condition immediately. This allows earlier detection of an error and makes the process of software development stress-free and unproblematic. It also provides maximum useful information of data structures and allows easy interpretation.
Debugging is the process of analyzing how your program runs, how it generates data in order to find defects and issues in your code. These errors or defects are referred to as “bugs”, hence the term “debugging.” Debugging is not always about finding problems in the code.
In the context of software engineering, debugging is the process of fixing a bug in the software. In other words, it refers to identifying, analyzing, and removing errors. This activity begins after the software fails to execute properly and concludes by solving the problem and successfully testing the software.

The terms "bug" and "debugging" are popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system.
Debugging means to run your code step by step in a debugging tool like Visual Studio, to find the exact point where you made a programming mistake. You then understand what corrections you need to make in your code and debugging tools often allow you to make temporary changes so you can continue running the program.
There are two types of debugging techniques: reactive debugging and preemptive debugging. Most debugging is reactive — a defect is reported in the application or an error occurs, and the developer tries to find the root cause of the error to fix it.
In hardware development, the debugging process typically looks for hardware components that are not installed or configured correctly. For example, an engineer might run a JTAG connection test to debug connections on an integrated circuit.
Which debugging technique is most used?
Trace-based debugging is traditional and the most common debugging technique used in most debugging tools today. Trace-based debugging is predicated on the concept of breakpoints.
Debugging itself is a very difficult process because of the involvement of humans. Another reason due to which it is considered as difficult because it consumes a large amount of time and resources too.

To find bugs, you need to:
- Be clear about your expectations.
- Check the results you get.
- Compare your expectations and the actual result to see what is missing.

In short, USB Debugging is a way for an Android device to communicate with the Android SDK (Software Developer Kit) over a USB connection. It allows an Android device to receive commands, files, and the like from the PC, and allows the PC to pull crucial information like log files from the Android device.
Debugging allows you to go through each line of code, evaluating your app's variables, methods and how well your code is working. It's easier to find small mistake in large pieces of code. In this article we will go through basic tips and tricks on debugging an Android app.
WiFi debugging uses TLS for encryption and authentication over the WiFi network. Each device creates a self-signed certificate for authentication. When connecting, a QR code is scanned to verify the certificates were presented by the correct devices.
The Enable debugging option turns on kernel debugging in Windows. This is an advanced troubleshooting method where startup information can be transmitted to another computer or device that's running a debugger. By default, that information is sent over COM1 at a baud rate of 15,200.
