Software engineering complete course free tutorial | Learn s-e easy with quiz door| Part 1

Let us first understand what software engineering stands for. The term is made of two words, 

software and engineering.

Software is more than just a program code. A program is an executable code, which serves some 

computational purpose. Software is considered to be collection of executable programming code, 

associated libraries and documentations. Software, when made for a specific requirement is 

called software product.

Engineering on the other hand, is all about developing products, using well-defined, scientific 

principles and methods.

Lets talk about s.e

😇

Software engineering is an engineering branch associated with development of software product using well-defined scientific principles,

methods and procedures. 

The outcome of software engineering is an efficient and reliable software

product.

Definitions:-

IEEE defines software engineering as:

(1) The application of a systematic,disciplined,quantifiable approach to the 

development,operation and maintenance of software; that is, the application of engineering to 

software.

(2) The study of approaches as in the above statement.

Fritz Bauer, a German computer scientist, defines software engineering as:

Software engineering is the establishment and use of sound engineering principles in order to 

obtain economically software that is reliable and work efficiently on real machines.
