Indented Code Format Answer:Multithreading is a technique used in software development to allow a single process to perform multiple tasks concurrently. This is achieved by dividing the process into smaller threads that can run independently, allowing the application to utilize available resources more efficiently and improve performance. In a multithreaded application, each thread runs separately, executing its own instructions and accessing shared resources, such as memory or a database. The threads communicate with each other through synchronization mechanisms, preventing conflicts or race conditions. Multithreading can be used in various scenarios, such as:- Improving application performance by utilizing multiple CPU cores and reducing wait times.- Handling multiple user requests concurrently, improving the scalability and responsiveness of web applications.- Performing time-consuming tasks in the background without blocking the user interface, such as file downloads or data processing.An example of multithreading in action is a web server handling multiple client requests simultaneously. Each request is assigned to a separate thread, allowing the server to serve multiple clients concurrently. As a software engineer, I have experience designing and implementing multithreaded applications, utilizing languages such as Java, C++, and Python. When using multithreading, it's crucial to ensure synchronization and manage shared resources carefully to prevent thread safety issues.Citations:- "Java Multithreading" by GeeksforGeeks: https://www.geeksforgeeks.org/java-multithreading/- "Multithreading: What Is It and How to Implement It?" by Toptal: https://www.toptal.com/java/guide-to-java-multithreading
