concurrency

What is meant by concurrency?

The term "concurrency" refers to the ability of a computer system to execute multiple tasks or processes seemingly simultaneously. This is achieved by the system rapidly switching between different tasks, creating the impression that they are running in parallel. Concurrency enables efficient use of system resources and improves the responsiveness of applications.

Typical software functions in the area of "concurrency":

1. Thread Management: Creation, management, and synchronization of threads for parallel execution.
2. Resource Sharing: Coordination of access to shared resources to avoid conflicts.
3. Synchronization Mechanisms: Implementation of mutexes, semaphores, and condition variables to control access to critical sections.
4. Task Scheduling: Planning and prioritization of tasks for optimal execution order.
5. Deadlock Detection: Identification and resolution of deadlock situations between competing processes.
6. Asynchronous Programming: Support for non-blocking operations and callback functions.

Examples of "concurrency":

1. Web Servers: Simultaneous processing of multiple user requests.
2. Multitasking Operating Systems: Execution of multiple applications side by side.
3. Database Management: Parallel processing of queries and transactions.
4. Graphics Rendering: Simultaneous calculation of different parts of an image.
5. Network Applications: Asynchronous processing of input and output operations.
6. Multimedia Software: Simultaneous processing of audio and video data.
