Learn Concurrent Programming with Go

2 Dealing with threads

This chapter covers

• Modeling concurrency in operating systems
• Differentiating between processes and threads
• Creating goroutines
• Differentiating between concurrency and parallelism

The operating system is the gatekeeper of our system resources. It decides when and which processes are given access to the various system resources, including processing time, memory, and network. As developers, we don’t necessarily need to be experts on the inner workings of the operating system.
