IIT BHU used to be an engineering course under the administration of BHU and was known as IT BHU. In 2012, the government granted IT BHU the status of an IIT. Since that moment IT BHU became IIT BHU, the sixteenth IIT of this country. The primary reason for the establishment of IITs was to promote research work in our country. IT BHU had a big contribution to research going on in India. Although IIT BHU still shares the same campus as BHU, it is a different institute. Being an IIT has brought many changes in IIT BHU. It is receiving more funds from the government. The research work has also boosted. Many state-of-the-art research equipment has also been brought into the college. So, that is the reason why IT BHU is now referred to as IIT BHU.
 

Before the commencement of the session 2017, internet used to be a limited resource for IIT(BHU). IIT Bhubaneswar used to be the Institute of Technology ( IT BHU), whose administration fall under Banaras Hindu university but it got a different stature in converting into IIT in 2012. Although, some facilities like Internet services were still under BHU administration for long.

So before 2017, there were limits on the internet usage of 4 GB and which could be accessed through LAN only and which this question asks about. But after it, IIT BHU gets its own wifi services and there is no cap on usage. Hence you can use as much data as you want once availing internet connection of college. So anyone today can surf more than 4GB in IIT BHU.

The reason behind why IIT BHU has never reached to ACM-IPC world finals is the lack of proper guidance and preparation. There are many good coders in IIT BHU and they practice competitive coding very seriously. In the past, students from IIT BHU reached the regionals but did not go ahead with the preparation for global finals as they fetched good job offers. Many coders have the potential to reach the finals, but they stop putting serious efforts when they are assured that they will be placed in their dream companies. Also, there was a lack of proper junior-senior interaction in the past years due to which proper guidance to reach the finals was not given. This trend has now been changed and now every week interaction sessions are being organized so that the first-year students are motivated properly from the very beginning. In these sessions, important algorithms are discussed and home works for the next session are being given. All these sessions are being organized and managed by Club Of Programmers (COPS). Because of these sessions, the students are well motivated from their first year itself and the number of blue coders on Codeforces has been increased from 2 to 7 and one of the students is Purple coder which means he is the highest-rated coder on codeforces. Because of their efforts, the coding culture of IIT BHU  has been improved and IIT BHU  secured second place at Kolkata-Kanpur regionals, so they will be representing the college for the world finals.

IIT BHU ranks 11th in the engineering category by NIRF 2019. The placement cell of IIT BHU offers various activities like pre-placement talks, expert talks, mock interviews, seminars, etc. to prepare the students for placements. Some of the recruiters of IIT BHU include Samsung, Deutsche Bank, Google, Oracle, Bajaj, HSBC Bank, J.P. Morgan, Amazon, etc. 
MTech in ECE students of IIT BHU in 2019 has seen the placement of 71%. The Department of Computer Science, Electrical Engineering, Electronics Engineering, and the Department of Mathematical Sciences has also maintained a very high placement record. The highest salary package offered to the students of IIT BHU is 58 lakhs per annum and the average salary package offered is 8 lakhs per annum. Top recruiters include EXL, Wipro, Tata Steels, Oracle, Morgan Stanley, and Maruti. Out of 300 students 171 were placed in the core engineering sector. Goldman, XEL selected 66 students along with 15 students in the year 2019-20 placement drive. University of Tokyo, University of London, University of New South Wales, Harvard University, Yale University, etc. are the top international universities that collaborate with IIT BHU for internship programs
The best courses in IIT BHU are- Mechanical Engineering, Computer Science and Technology, Electrical Engineering, Electronics Engineering, Chemical Engineering. They have the largest number of students ranging from 88-109. These are the most popular courses in IIT BHU. The Department of Computer Science and Technology, Electrical Engineering and Electronics Engineering has the highest placement record.
 

6 institutes, 14 faculties, and 140 departments comprise the whole of Banaras Hindu University. Before 2012 IIT-BHU was known as IT (Institute of Technology) and hence was under the administrative control of BHU itself. After 2012, IT BHU gained the status of IIT and became an autonomous institution. Since it is located inside the BHU campus, it is popularly called IIT-BHU. Otherwise, it can be called IIT-Varanasi too. It runs according to the IIT-council rules but doesn’t have a separate VC. The VCs are the same as that of BHU. Another major difference between these two institutes is in the mode of admission. BHU conducts its own admission test while IIT admission takes place through JEE mains and advance, GATE & GPAT.
