Computer Science Engineering

Computer Science Engineering (CSE) is an engineering discipline that covers several topics related to computation, programming languages, program design, computer hardware and software and integrates several fields of computer science. It is one of the trending subjects which students pursue after completing Class 12. Engineering in computer science is one of the essential parts of education, and it is a fact, no doubt. B-tech in computer science is one of the necessary and accessible career paths. It is also the most common one that the students follow, so we can say that it's a good option ahead. Both Computer Science and Computer Engineering are difficult degrees. They deal with different areas of Mathematics (logical proofs and data structures for CS, calculus for CE) and aren't a great choice for students who want to take it easy and focus more on enjoying college life. 

Aeronautical Engineering

Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use.[4] Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". 

Mechanical Engineering

Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems.[1] It is one of the oldest and broadest of the engineering branches. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. 

Electronics Engineering

Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics.  

Biotech Engineering

Biotechnology engineering is a field of applied biology and chemical engineering principles that involves the use of living things in engineering, technology, medicine, and other useful applications. It also includes genetic engineering as well as cell and tissue culture technologies. Biotechnology is a collection of combined technologies applied to living cells for production of a particular product or enhancing its quality. This might involve domestication of animals, cultivation of plants and "improvements" through breeding, artificial selection and hybridization.
