Course Organization Questions?

Course Objectives You are expected to u learn basic concepts and principles behind the design of operating systems u get exposed to the problems operating systems designers face, explore the tradeoffs and solutions to these problems u see how are these issues solved in practice in real operating systems u be able to apply these concepts and techniques in relevant circumstances u get some hands-on experience programming OS type problems (process creation, inter-process-communications, process synchronization, mutual exclusion, deadlock avoidance)

Topics Covered n What Operating Systems Do n Computer-System Organization n Computer-System Architecture n Operating-System Structure n Operating-System Operations n Process Management n Memory Management n Storage and I/O Management n Protection and Security n Distributed Systems n Special-Purpose Systems n Computing Environments Background/intro The main stuff Advanced topics, not covered in this course

Topics Covered Introduction/Background/Overview u Computer systems overview u Operating systems overview: interface, system calls, design and implementation issues, OS structure Process Management u Processes and threads u Interprocess communication u CPU scheduling – algorithms and criteria u Process/thread synchronization – problems and solutions u Deadlocks – prevention, avoidance, detection, recovery

Topics Covered (contd.) Memory Management u Basic main memory management (swapping, contiguous memory allocation, paging, segmentation) u Virtual memory (demand paging, copy-on-write, page replacement, allocating kernel memory) Storage Management and Input/Output u File-System interface (files, directories, mounting file system, file sharing) u File-System implementation u Mass-storage structure (disk structure, scheduling, management) u Swap space management u I/O systems (hardware, application I/O interface, kernel I/O subsystem)
