# operating\_systems

## Basic idea

OS topics relevant to distributed systems: memory and address spaces, processes and threads, IPC, and how these are extended (or not) across machine boundaries.

## Key facts

* Networked OS: each host autonomous, user does explicit network ops.
* Distributed OS: location transparency — the OS hides the network from the user.
* Core primitives: processes, threads, address spaces, file descriptors, IPC.
