Go CSP

Linux Inter-Process Communication (IPC) encompasses various methods that allow different processes to exchange data and synchronize with each other. These methods include:

1. Anonymous Pipes and Named Pipes (FIFO - First In First Out)
2. Signals and Semaphores
3. Message Queues
4. Shared Memory
5. Sockets and HTTP

The CSP (Communicating Sequential Processes) concurrency model in Go language is one of its core features. The concept of CSP is primarily embodied in the following two aspects:

1. Goroutines：Goroutines are the entities that execute concurrently in practice. Each Goroutine communicates with others through channels to achieve data sharing and coordination. The lightweight nature of Goroutines makes it easy to create thousands of concurrent tasks without consuming excessive resources like traditional threads.
2. Channels：Channels are the most crucial component in the CSP model. They are used to pass data between Goroutines, similar to pipes or queues in other programming languages. Channels support both blocking and non-blocking read and write operations, ensuring data synchronization and consistency.

In the CSP model, each concurrently executed task is independent, and they communicate with each other for data exchange and coordination. In other words, CSP emphasizes organizing concurrent behavior through communication rather than directly sharing memory, thereby avoiding issues like race conditions and deadlocks that can arise from direct memory sharing. This approach makes concurrent programming easier and safer.
