These branches almost appear to deal with the same domain. But the nature of subjects taught varies between the pairs. We take you through a brief overview of what is in store for you across disciplines so that you pick what you enjoy.
Information Technology (IT)/Computer Science (CSE)
Offering papers like fuzzy logic advanced programming, computer languages, embedded systems, distributed operating systems, compiler design, advanced networks, the CSE branch primarily specialises in the core computing area. So you would ideally work with corporations like GE Research Centre, Microsoft Research.
On the other hand, the IT branch has object- oriented programming, database structures, Software project management, software engineering, and functional programming, System Analysis and Design and deals with development of application packages and usage of computers. You will do work with corporations like Infosys, Accenture, Wipro etc.
Between them unless you have a research orientation, it would make sense for you to choose IT specialisation. But in terms of number of seats, CSE (206,303) scores over IT (125,472). So it would be easier to get CSE than IT.
Electronics & Telecommunication / Electronics & Instrumentation
Though electronics forms the common core, in each semester from the fourth semester onwards, the course offerings differ quite a bit. The telecommunication option has papers like television engineering, radiation and propagation, microwave laboratory, radar and navigation, antenna theory etc. It is primarily suited to individuals interested in working in the telecom vertical. The operating discipline here is telecommunication domain.
The Instrumentation specialisation is a recent offering and very few colleges do offer this specialisation. Here you would do courses like analytical instrumentation, computer networks, real time and embedded systems, robotics, transducer laboratory amongst others. It is more hardcore electronics and hence job opportunities would be there in almost all verticals, which have electronics. Unless you have a special interest for telecom, it might make sense to opt for plain electronics or a combination with instrumentation.
Industrial/Production
Between them production engineering is a relatively focused specialisation. It attempts to teach you courses like metal cutting, thermal engineering, process control, mechatronics, mechanical systems, dynamics of machines etc. It primarily equips you to work in large scale industrial concerns like Reliance, Ashok Leyland, BHEL, NTPC, Dow Chemicals, Tata Steeel etc. It is a hands- on domain and requires certain physical toughness.
On the contrary, industrial engineering is
slightly more sophisticated in terms of its course offerings. It has papers like cost estimation, quality control, facilities engineering, evolutionary optimization, reliability engineering etc. It deals with work that precedes actual manufacturing and is heavily computing dependent. Your work invariably would not be in the shop floor, but in the control room.
Electrical /Electronics
Both the disciplines have core papers on electrical and electronics domain like electromagnetic theory, circuit analysis, digital electronics, and microprocessors amongst others. While the electronics specialisation then moves on to offer a range
of electives encompassing all the allied fields like instrumentation, telecommunications, computing and IT, the electrical specialisation moves into focused papers on the sector.
From the fourth semester onwards, you have papers like Generation of electrical power, power electronics, transmission engineering. Static protective relays, electrical machines, which help you develop competency in electrical engineering vertical. In other words work by GE, Siemens, Schineder Electric, BHEL, NTPC etc. If you are not very clear as to what it is that you want to do in electronics, but have general liking for circuit branches, then you must opt for electronics engineering.
