What is the essence of multithreading?

Multithreading allows multiple tasks to be executed simultaneously within a single process, improving application performance and responsiveness.

Main aspects:

• Parallelism: Executing tasks on multiple CPU cores.
• Concurrency: The illusion of simultaneous task execution on a single core through context switching.
• Responsiveness: Preventing blocking of the main UI thread, allowing the application to remain interactive during long-running operations.
• Resource utilization: More efficient use of CPU and I/O resources.

Applications:

• Server applications for handling concurrent requests.
• Graphical interfaces for performing background tasks.
• Parallel computations to accelerate data processing.
• I/O operations, such as reading from a file or network requests, without blocking the main thread.
