الله يخليكم حد معه حل لهلاسايمنت ضروري اذا حد عارف الاجابة لا يبخل علينا
جعله الله في ميزان حسناتكم

Part A: Report on “threads” in an operating system of your choice
1- Write a detailed report on how threads are implemented in an operating system of your choice such as Windows XP, Linux, FreeBSD, Mac OS X , ….etc.
2- Your report must include how threads are implemented in the operating system, how user level threads map to kernel threads and threading models used by that operating system .
3- Also include any other information for the threads in the operating system that you have chosen – such as creation and termination of threads in that operating system, memory and time taken to create threads and the performance of the system when doing thread operations.
4- Include diagrams and figures in your report wherever possible – but you MUST give the reference when using the diagrams or figures from a website, paper or book.

Part B: Example on data sharing using “Shared Memory”
A “shared memory” is one of the solutions to data sharing between cooperating processes which require an
Inter-process communication (IPC).
1- Based on lecture three of your course, you should give a programming example on Shared-Memory solution to the Producer – Consumer problem.
2- Your programming example must show how to create the buffer and the buffer interface also must include the Producer process, the Consumer process.
3- You may need to read your book (section 3.4.1 pp 102-104).
