What Is Debugging on Your Computer?
Although software programs are written with the intention of their working flawlessly, they often have bugs or problems that have to be dealt with. Debugging is a process that involves locating and removing bugs -- programming errors -- from software programs or from the computer operating system. By debugging, developers can improve the performance of software programs for users.

Analyzing Code
-
In order to debug a program or application, a user needs to be able to see the code for that program. The bug may be easily discovered when the program is running, but it will have to be fixed inside the code itself. In many cases, the issue is something very small inside the code that is simply not noticed when it is initially reviewed. Once the error is identified in the program, the developer can then go to that specific area in the code and fix the problem.
Debuggers
-
While users can debug a software program manually, they often rely on programs known as debuggers to help with this process. A debugger is a program that scans through the code of a new program to see if it can find any common errors. Debugging tools can be a valuable time saver and can catch many obvious errors. Most of the time, the developer of a program will have to look at the code after the debugger is completed as well.
-
Beta Testing
-
With many commercial pieces of software, developers use a beta testing phase to help with the program. Beta testing is a process in which the software is released to a limited group of beta testers to try out the program. The purpose of beta testing is to see if users of the program can find any problems with it. If a user finds a problem with the program, it is reported to the developer so that the issue can be fixed.
Components
-
When developing complicated software products, developers often engage in debugging on a unit level before compiling the program. They look at each individual unit of the software program to find out if it has any problems before the units are combined to make the full software program. This is often required with larger programs because it is so difficult to debug once all of the individual codes have been added together.
