JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives:

• 1. To know the different advantages and limits of fault avoidance and fault tolerance techniques.
• 2. To impart the knowledge about different types of redundancy and its application for the design of computer system being able to function correctly even under presence of faults and data errors.
• 3. To understand the relevant factors in evaluating alternative system designs for a specific set of requirements.
• 4. To understand the subtle failure modes of "fault-tolerant" distributed systems.

Course Outcomes

Upon the Successful Completion of the Course, the Students would be able to:

• 1. Become familiar with general and state of the art techniques used in design and analysis of fault tolerant digital systems.
• 2. Be familiar with making system fault tolerant, modeling and testing, and benchmarking to evaluate and compare systems.
