Whether it’s reconstruction a car engine or diagramming a sentence, one can learn about many things just by taking them apart and putting them back together again. That, in a nutshell, is the concept behind reverse-engineering—breaking something down so that we can understand it, build a copy or improve it.
A process that was initially applied only to hardware, reverse-engineering is now applied to software, databases and even human DNA as well. Reverse-engineering is highly important with computer hardware and software. Programs are written in a language; say Java or C++, that’s understandable by other programmers. But to run on a computer, they have to be converted by another program, called a compiler, into the zeros and ones of machine language. Compiled code is unintelligible to most programmers, but there are ways to change machine code back to a more human-friendly format, including a software tool which is known as a decompiler. Reverse engineering is used in a variety of fields offered by the best engineering college in pune such as software design, software testing, programming etc.
Reverse-engineering is used for many purposes: as a learning tool; as a way to make something new, compatible products which are at low-priced than what’s currently in the market; for making software work more effectively or to bridge data between the different operating systems or the databases.
Reverse engineering, is basically the process of taking a software program’s binary code and replenishing it so as to trace it back to the actual source code, is being widely used in computer software and hardware to enhance product features or fix certain bugs. For example, the programmer writes the code in a high-level language such as C, C++ and etc. As computers don’t speak these languages, so the code written in these programming languages needs to be gather in a format that is machine specific. In short, the code written in high-level programming language needs to be interpreted into low level or machine language.
The process of converting the code written in high level programming language into a low level language without changing the original program is called as reverse engineering. It’s similar to dismantling the parts of a vehicle to understand the main and basic functioning of the machine and internal parts etc. and after that making appropriate adjustment to give rise to a better performance of a machine and making a superior vehicle.
If we have a look at the subject of reverse engineering (RE) in the context of software engineering, we will find that it is the practice of examining the software system to extract the actual design with implementation information. A typical reverse engineering scenario would comprise of a software module that has been worked on for number of years and carries the line of business in its code; but the original source code might be lost, leaving the developers only with the binary code. In such a case, reverse engineering ability would be used by software engineers to identify probable malware and virus to eventually protect the cognitive property of the company.

In simple word we can say reverse engineering is the practice of taking something which already exists and peeling away its layers to better understand exactly what makes it active.
