SOFTWARE ENGINEERING

Some terms

Software = the programs and other operating information used by a computer.

Engineering = the branch of science and technology concerned with the design, building, and use of engines, machines, and structures.

Software engineering

Software engineering is a field of engineering, for designing and writing programs for computers or other electronic devices. A software engineer, or programmer, writes software (or changes existing software) and compiles software using methods that make it better quality.

Computer software

Computer software (often called just software) is made of one or more computer programs. Sometimes it means one specific program, or it can mean all the software on a computer, including the applications and the operating system. Applications are programs that do a specific thing, such as a game or a word processor.

Software development engineers

Software development engineers (SDE) work in a range of industries to apply the principles and techniques of computer engineering, information analysis, and computer science to design, build, and develop their employers' computer systems and software.

UNIT- I

Software engineering (SWE) is the application of engineering to the development of software in a systematic method.

Typical formal definitions of software engineering are:

• "research, design, develop, and test operating systems-level software, compilers, and network distribution software for medical, industrial, military, communications, aerospace, business, scientific, and general computing applications."
• "the systematic application of scientific and technological knowledge, methods, and experience to the design, implementation, testing, and documentation of software";
• "the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software";
• "an engineering discipline that is concerned with all aspects of software production";
• and "the establishment and use of sound engineering principles in order to economically obtain software that is reliable and works efficiently on real machines.
