Software Engineering

There are multiple job opportunities available in the field of software engineering (IT). As per NASSCOM, Indian IT Industry revenues grew by 13% in FY2015 and it added 2,30,000 employees in FY15. NASSCOM has forecasted that IT industry exports will grow by 12-14% and domestic market by 15-17% in FY2016 (Actual data is yet to be released). India's IT-BPM industry is projected to grow ~8% in FY2017 to USD 154 billion.
Following are the options for joining software companies after 10+2:
(a) B.Tech CS or B.Tech IT
(b) BCA
(c) B.Sc CS or B.Sc IT
(d) Diploma in Computer Science
(e) Training from training institutes.
CSE & IT grads from top engineering colleges have excellent career opportunities among all the options mentioned above. Following options are available for any graduate to become a software engineer after graduation degree if the candidate had maths as a subject in 10+2:
(a) MCA
(b) M.Sc CS or M.Sc IT
MCA graduates are treated equally to B.Tech CS.
Any engineering graduate can appear in GATE examination and do M.Tech computer science to become a software engineer.

Hello Suchitra,
Of course, there are difference between the two. Although, no two computer professionals explain those differences in the same way. One way to understand the differences is to examine two specific words within the given nomenclature; namely, engineer and science (or scientist). Engineers, by nature, are tasked with developing solutions to problems or creating more efficient processes by using tools already in existence. By extension, software engineers often find themselves creating new software by utilizing existing languages or established practices already in use. Contrary to this, scientists often hone their expertise on research and developing (and pushing) the boundaries of their given field. As such, computer scientists may assist in the creation of new algorithms or language types that will eventually be put in use to create software.
Ultimately, both are concerned with computer software and virtually everything related. The focus of these two fields of study overlaps in that both require the student to develop an intimate knowledge of computers, and especially computer software and its various applications.

Computer science is a study of the theory, applications of engineering principle for the design and use of computers based systems. Computer science and engineering deals with design, implementation, and management of software & hardware based information system and electronics systems to automate processes. Computer science deals with mostly software aspect of Systems and Application Development. Computer engineering, mainly, is a field related to computer hardware. Nowadays, most of the engineering colleges offer CSE degree where students undergo both software and hardware courses. B.Tech in CSE graduate specialises in the theory of computation and design of computational systems. CSE graduates are trained to integrate several disciplines such as Information Technology, Electrical and Electronics Engineering, Software Design, etc. The CSE graduates are mainly involved in the development of software and hardware systems of various aspects of computing for products, systems and Information Systems.
B.Tech IT degree has a major focus on computers and technology, it differs from a Computer Science degree in that students are also expected to study management and information Science, and there are reduced requirements for mathematics and theory of computation.
Software Engineering (SE) deals with building and maintaining software systems. It is more applied than Computer Science, placing greater emphasis on the entire software development process, from idea to final product. It is also more disciplined than Computer Science, applying more systematic practices to help ensure that products are reliable and safe. There is only subtle difference between CSE, IT and SE. IT Industry accepts all three to start career as Software Developer.
