Reverse engineering is the process of analyzing a product or system in order to understand how it works, with the ultimate goal of either replicating its functionality or improving upon it. This process involves examining the components, structure, and behavior of a product or system in order to extract valuable information that can be used for various purposes such as improving the design, enhancing functionality, or identifying security vulnerabilities. Reverse engineering is commonly used in various industries, including software development, manufacturing, automotive, and electronics, among others.
