Knowledge of debugging

In computer operations, numerous errors occur therefore it is imperative to fix those errors for smooth functioning of system.

In computer devise, experts do debugging to eradicate errors. It is the process of tracing and fixing or avoiding bugs (errors) in computer program code or the engineering of a hardware device. For debugging a program or hardware device is to begin with a problem, separate the source of the problem, and then fix it. An operator of a program must be trained to fix the problem permanently. Software debugging is one of the prime job of programming.

In developing software programs, users perform rigorous testing, updating, troubleshooting and maintenance. Usually, software has many errors and bugs, which must be regularly eliminated. In the debugging process, complete software programs are frequently compiled and performed to recognize and resolve problems. Huge software programs, which contain lots of source code lines, are divided into small constituents. To enhance efficacy, primarily, each component is debugged independently then followed by the program as a whole.

Actually, debuggers are tools that investigate the statue of an operating program. Common debuggers include adb, dbx, gdb, kdb, wdb, xdb. Microsoft Visual Studio has an integrated debugger.

In system, debugging is essential process in any new software or hardware development process, whether a commercial product or an enterprise or personal application program. For multifarious products, debugging is performed as the result of the unit test for the smallest unit of a system at component test when parts are brought together. It can be done at system test when the product is used with other existing products and during customer beta test, when users try the product out in a real world situation. Most of the computer programs and many programmed hardware devices include huge of lines of code, almost any new product is likely to contain a few bugs. Customarily, the bugs in the functions that get most use are found and fixed first.

It can be said that debugging tools aid to examine coding errors at several development stages. Some programming language packages include a facility for checking the code for errors as it is being written.

In brief, debugging in software devices is the regular procedure to locate, rectify and fix computer program bugs, errors or irregularities, which is systematically controlled by software programmers through debugging tools. Debugging checks, detects and corrects errors or bugs for good program operation as per set specifications.
