What is a tech stack?

• A. A stack of hardware equipment
• B. A combination of programs, solutions, and services to build or run an application or project
• C. A list of cloud services
• D. A data storage archive

Answer: (B)

A tech stack is the combination of programs, solutions, and services used to build or run an application or project. It includes everything from the client-side code and UI frameworks to the server-side languages, databases, APIs, and the infrastructure that hosts and runs the app (often spanning cloud services and deployment tools). This is why the best answer is that it’s an integrated set of technologies that work together to create and operate software. For example, a common web stack might use React on the front end, Node.js on the back end, PostgreSQL for data, and a cloud platform with APIs and CI/CD tooling. The other ideas miss important parts: hardware stacks are about physical equipment, a list of cloud services is only part of the picture, and a data storage archive is just storage, not the whole system that runs an application.
