Reverse engineering is the process of analyzing a product or system to understand its design, functionality, and components. This technique is often used in software development, where programmers deconstruct applications to learn how they work or to identify potential vulnerabilities. It can also apply to physical products, allowing engineers to recreate or improve existing designs. In the field of technology, reverse engineering can lead to innovation by providing insights into how products like smartphones or automobiles operate. It is also used in cybersecurity to discover weaknesses in systems, helping to enhance security measures and protect against threats.
