For all other computers 3rd sem syllabus for diploma m scheme tndte you can visit Computers 3rd Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for operating systems is as follows.

Rationale:

The heart of a computer is based around its Operating System. The processor deals with request coming from all directions asynchronously. The operating system has to deal with the problems of Contention, resource management and both program and user data management, and provide a Useful no-wait user interface. The concept of Operating System is discussed through case studies of LINUX. The course provides clear vision, understanding and working of Operating Systems.

Objectives:

• Understand the purpose, goals, functions and evolution of Operating Systems.
• Understand the concept of process, various states in the process and their scheduling.
• Classify different types of schedulers and scheduling algorithms.
• Identify the significance of inter-process communication and synchronization.
• Discuss the usage of semaphore in inter-process communication.
• Understand the conditions for a deadlock.
• Describe the ways to recover from the deadlock.
• Know about memory protection against unauthorized access and sharing.
• Compare and contrast paging and segmentation techniques.
• Define virtual memory and its underlying concepts.
• Describe the page replacement policies like Optimal, FIFO and LRU.
• Discuss the disk scheduling techniques.
• Mention the role of security policies
• Discuss about significance of authentication
• Describe the features and brief history of Linux
• Compare Unix and Linux
• Explain Linux architecture
• Describe the process management, memory management handled by LINUX
• Describe file management , device drivers handled by Linux
