Software architecture: high-level system structure showing how components organized, communicate, and divide responsibilities.
Software development stages: understand requirements and define problems, plan architecture and tech stack, develop and test, then deploy.
Technical debt: shortcuts or suboptimal solutions making future development harder. Like financial debt, borrow time now, pay interest later.
Software testing: unit tests check individual functions, integration tests verify components work together, end-to-end tests validate workflows.
