The Indian Institute of Technology (IIT) provides a range of online courses tailored for students seeking in-depth knowledge in various subjects. These courses are offered free of charge and come with a certification upon completion. The online curriculum typically comprises recorded lectures on specific topics and fields of study. Students have the flexibility to select courses aligned with their qualifications and interests. IITs offer diverse courses such as Aerospace Engineering, Machine Learning, Software Testing, and Elements of Mechanical Vibration. These courses may be conducted by the same institute or different IITs.

Let's delve into a few of these courses:

1. Aerospace Engineering: IIT Bombay, through its Aerospace Department, offers this course which delves into the intricacies of aeronautical engineering. Beyond the online coursework, the department also hosts workshops and seminars that cover current technological advancements. This course caters to individuals passionate about aerospace.

2. Software Testing: IIT Kharagpur delivers this course, providing a concise introduction to testing processes and techniques, including black box and white box test case design. The curriculum also encompasses integration, system, and regression testing, shedding light on various loading methods. The course spans 28 hours of study material.

3. Machine Learning: Another offering from IIT Kharagpur, this course educates students on fundamental concepts like linear regression, logistic regression, and base algorithms for machine learning. Participants can acquire a deep understanding of machine learning through this course, which extends over 8 weeks and caters to both undergraduate and postgraduate students.

4. Aircraft Stability and Control: IIT Kanpur presents this course, aiming to provide insights into the stability and control mechanisms of airplanes. The course duration is 12 weeks.

In a collaborative effort, seven prominent IITs, along with Infosys, TCS, Cognizant, and Nasscom, have launched a series of free online courses. This initiative aims to facilitate education for 100,000-150,000 students. The courses mentioned above are integral components of this endeavor, encompassing a wide array of subjects that equip students with practical skills for employment. These courses are facilitated through the Massive Open Online Courses (MOOCs) model.
