What is software engineering?

Software engineering is the disciplined practice of designing, building, testing, and maintaining software systems — not just writing code, but delivering reliable products teams can evolve over years.

Exam tip: keep SI units consistent end-to-end, write the governing relation symbolically before substituting, and sanity-check magnitude and sign.

Understand the concept

It includes requirements, architecture, version control, code review, automated testing, deployment, and monitoring. Software engineers collaborate with product, design, and operations teams.

Difference from computer science

Computer science emphasizes theory and algorithms; software engineering emphasizes shipping and sustaining systems in production with real users and constraints.
