Operating systems (OSes) are required on all computing devices to run software on top of hardware. These notes delve into the details on some experimental operating systems from the 1980's through the mid-2000's, expanding from OSes contained on a single device to networked, scalable, distributed operating systems spanning networks or even over the Internet. This course and the associated notes serve as a solid foundation and introduction to operating systems and distributed systems, starting with the genesis of the modern computing machine.
