Operating Systems - Synchronization
This document discusses synchronization in operating systems and concurrent programming. It introduces the concept of critical sections and mutual exclusion locks that allow only one thread to access shared data at a time. It presents solutions to the "too much milk" problem using notes and waiting to ensure only one thread buys milk at a time. The document then discusses implementing locks using disabling interrupts as well as higher-level synchronization primitives like semaphores and monitors that make concurrent programming easier.
