Posix Threads (Pthreads) Concurrency Chapter 26 Abstraction: Threads Here we introduce a new abstraction for a single running process: that of a thread. The state of a single thread is thus very similar to that of a process. It has a program counter (PC) that tracks where the program is fetching instructions from
