Words to know
- Random
- Chosen by chance so every option has an equal, unpredictable chance of being picked.
- MAC address
- A hardware ID burned into every network card, like a serial number. It works only on your local network.
- Beautify / format
- Adding line breaks and indentation so code is easy for humans to read. It does not change what the code does.
- Unit conversion
- Changing a value from one measurement to another, like kilometers to miles. The amount stays the same; only the unit changes.
- SSID / WPA
- SSID is your Wi-Fi’s name. WPA2/WPA3 is the password protection used by almost all routers.
