About processes, threads, and goroutines

A process is an execution environment that contains instructions, user data, and system data parts, as well as other types of resources that are obtained during runtime, whereas a program is a file that contains instructions and data that are used for initializing the instruction and user-data parts of a process.

A thread is a smaller and lighter entity than a process or a program. Threads are created by processes and have their own flow of control and stack. A quick and simplistic way to differentiate a thread from a process is to consider a process as the running binary file and a thread as a subset of a process.

A goroutine is the minimum Go entity that can be executed concurrently. The use of the word "minimum" is very important here, as goroutines are not autonomous entities like UNIX processes – goroutines live in...
