Concurrency is a fundamental concept in computer science that allows multiple tasks or processes to execute simultaneously or appear to do so. It is crucial for improving the efficiency and responsiveness of applications, particularly in systems that require high performance and resource utilization.
Non-blocking refers to a design pattern in software development where operations do not block or wait for each other. This allows multiple tasks or threads to execute concurrently without interfering with one another.
Concurrent programming refers to a programming paradigm where multiple tasks or processes are executed at the same time. This does not necessarily mean that they run simultaneously (as in parallel computing), but rather that they make progress independently, potentially switching between tasks to maximize efficiency.
