
An operating system (OS) is



a software system that provides its users with a
convenient interface
masking hardware details from users and
programmers, e.g., with the OS, one needs not to
develop application programs in machine instructions
Goal:


Get familiar with operating system internals
Study the design and implementation of OS kernels
Topics Covered



History and overview of operating systems

Memory management
System calls
Handling of interrupts and exceptions
Low level hardware/software interface
Race condition and critical sections
Deadlock
I/O hardware and software (if time permitted)
