Threading
Threading is a technique used in programming to execute multiple parts of a program at the same time. Each part of the program that is executed simultaneously is called a thread. Threads allow a program to perform multiple tasks concurrently, which can improve the overall performance and responsiveness of the program.

Key Points:
- Threads run independently of each other within the same program.
- Threads share the same memory space, allowing them to communicate and share data with each other.
- Threading is commonly used in applications that require handling multiple tasks simultaneously, such as web servers, video games, and multimedia applications.
- By using threads, a program can take advantage of multi-core processors to execute tasks in parallel, leading to improved efficiency and speed.

Benefits of Threading:
- Improved performance: Threading allows a program to utilize the available resources more efficiently by running multiple tasks concurrently.
- Responsiveness: Threading can help prevent a program from becoming unresponsive by allowing it to continue running tasks in the background while performing other operations.
- Scalability: Threading enables a program to scale and handle more tasks as the workload increases, making it suitable for applications with varying levels of demand.

Challenges of Threading:
- Synchronization: Ensuring that threads access shared resources in a coordinated manner to prevent conflicts and data corruption.
- Deadlocks: Occur when two or more threads are waiting for each other to release resources, causing the program to freeze.
- Overhead: Managing threads can introduce additional complexity and overhead to a program, potentially impacting its performance.
