Multithreading is a programming concept that allows multiple threads (smaller units of a process) to execute concurrently within a single application. This approach enhances performance, responsiveness, and resource utilization, especially on multi-core processors.

Key Concepts

A thread is the smallest unit of execution within a process. Threads within the same process share resources like memory and files, enabling efficient communication. In contrast, a process is an independent program with its own resources. Multithreading allows a single process to perform multiple tasks simultaneously, improving efficiency.

For example, in a web browser, one thread can handle user input while others load web pages or process background tasks.

Benefits of Multithreading

• Increased Performance: Tasks can run in parallel, reducing execution time.

• Improved Responsiveness: Applications remain interactive even during intensive operations.

• Efficient Resource Utilization: Threads maximize CPU usage by keeping cores busy.
