Terminal (PowerShell)
A tool for controlling the computer with text commands (PowerShell/cmd/bash) — type a command, press Enter, get a result. Why: half of real developer work happens in the terminal — git push, gradle build, adb install, deploy — these have no button, only a command. And commands turn into scripts you can repeat with a single motion. When: every working day. How: command + parameters → the OS executes → result on screen; the pipe `|` streams one command's output into the next. Where: Windows Terminal / PowerShell on your PC, the IDE's own Terminal tab, and from Phase 13 onward, a Linux server's bash (same principle). Who: developers, DevOps, anyone who doesn't want to do the same thing twice by hand.
