This course will provide an introduction to operating
system design and implementation. The operating system
provides a well-known, convenient,
and efficient interface between user programs and the
bare hardware of the computer on which they run. The
operating system is responsible for
allowing resources (e.g., disks, networks, and
processors) to be shared, providing common services
needed by many different programs (e.g., file
service, the ability to start or stop processes, and
access to the printer), and protecting individual
programs from one another. The course will start with
a brief historical perspective of the evolution of
operating systems over the last fifty years, and then
cover the major components
of most operating systems. This discussion will cover the
tradeoffs that can be made between performance and
functionality during the design and
implementation of an operating system. Particular
emphasis will be given to three major OS subsystems:
process management (processes, threads,
CPU scheduling, synchronization, and deadlock), memory
management (segmentation, paging, swapping), file
systems, and operating system support
for distributed systems. The course programming
assignments are in Java/C.
