In Layman language debugging is the process of removing errors or bugs from any software or hardware but then again in technical terms it is the way of detecting, locating the source of errors and fixing the problems caused by the bugs or errors in the codes of the computer software or in the programs of hardware of a computer. A user, in general, does not know about the bugs that have been attacking their system until it does not harm enough to notice as bugs may perform silent memory corruption.
Debugging is more complicated if there are more than one system is interconnected because bug or errors are not something that can be easily detected just by overlooking the devices. The process of finding loopholes in the coding and then rectifying it is called debugging and it is a very complicated process and mainly involved in the initial stage of any new software or hardware and is very important to debug before launching any kind of programs etc.
Furthermore, it involves series of the high-end process which involves collection of data its analysis and then scheduling its debugging accordingly which normally takes a huge amount of time and for simplifying the process there are numerous Debugging Tools are in the markets. With the help of such tools like exception handling for java based programs, memory debugger for others BIOSes, Logic analyzers, in-circuit emulators etc., makes it easier to find loopholes and then fix it as required. Apart from that, there are many traditional ways of debugging which includes stepwise removal of bug or error manually than with the help of tools for complete removal of bugs or any possibility of bugs.
With the help of debugging tools, it is very easy to detect an error in the writing stage of programs. Apart from that, there are numerous methods for the removal of bug from both programs and systems like Print debugging, Remote, Post-mortem Debugging, Wolf-fence debugging, Delta debugging, staff Squeeze etc. depending upon the effect it has on the system. Like Post-mortem one is used when bug had completely crashed the program and Delta one is for automatic testing in case there is an attack of bug. Moreover, there is a very common saying that prevention is better than cure so taking precautionary steps seems like a good option.
Talking about the good things than Debugging after coming into limelight had been the greatest remedy to all those problems which may arise after the launch or set up of any software or hardware. As these bugs which tend to get attached at the very initial stage or when a program is being written to a high level of preventive measure is pretty necessary to avoid any such situation. Nevertheless, debugging is the great boost to all those who are in the field of writing and developing programs as it cut short a huge amount of time and failure percentile of any coding of programs.
