Module Aims Analysis of major principles of Operating System Introduction to some of the programming principles required in improving the efficiency of modern Operating Systems 3 3

Topics to be covered Operating system principles Main memory management: Virtual memory and caches Processor Management management of process and threads principles of concurrency and synchronisation process: creation and synchronisation threads creation and synchronisation principles of deadlock and starvation File management: files on secondary storage

Topics to be covered programming for operating systems Basic C programming concepts Using Functions in C Concept of pointers, pass by reference… Structures (heterogeneous data type) Link lists, Stacks and Queues Process Creating and synchronisation using C (Thread creation and synchronisation using C) {

Labs: Linux environment The Linux Operating System will be used for the module computer. Students will able to access the linux environment in a number of ways referred to below. Putty client (this is the preferred method and the one used in the computer labs and for lab tests – you will have to be registered to use this method) An online linux/ubuntu emulator: such as tutorial point or code academy (need to create an account ) or any other online emulator An off line version using virtual box and ubuntu/linux environment (you will be given the essential files for a windows 7 32 bit version) A linux labtop/desktop or a mac book also works.
