Goroutine in processes, threads, lightweight processes, co-routines, and go

This is a creation in Article, where the information may have evolved or changed. Processes, threads, lightweight processes, goroutine, and go in the phone interview was asked to go to the association, once the military Wei also asked me to the association process. Although in Python time in Eurasia and Eventlet understand the association, but their concept of the association is a lightweight thread, there is a very popular traffic lights saying: thread to keep the rules, the

that the main method execution is a co-process, but the Go runtime does not start the process. The process can be considered lightweight because they consume very little memory and resources, and it initializes a small stack space. The previous Go language 1.2 version stack space will be initialized to 4 K, and the current 1.4 version will be initialized to 8K. This stack can automatically add space as needed. The operating system schedules the avail

Python: threads, processes, and co-routines (1)--Concepts

process has its own address space, memory, data stack, and other secondary data that records its running trajectory. The operating system manages all the processes running on it and distributes the time fairly for those processes. Processes can also perform other tasks through fork and spawn operations, but each process has its own memory space, data stack, and so on, so it can only use interprocess communication (IPC) instead of sharing information directly.(iii)
