About Software Engineering

Software Engineering is the application of a systematic,disciplined,quantifiable approach to the development,operation and maintenance of software; that is, the application of engineering to software. It consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system While a computer program is a set of instructions (source, or object code) a software system has many more components such as specification, test results, end-user documentation, maintenance records, etc.The term software system should be distinguished from the terms "computer program" and software. The term computer program generally refers to a set of instructions (source, or object code) that perform a specific task. However, a software system generally refers to a more encompassing concept with many more components such as specification, test results, end-user documentation, maintenance records, etc.
