The terminal apps that are built into python.microbit.org online editor and the Mu software give you two ways to interact with your micro:bit:
Most of the Cybersecurity tutorials will utilize the terminal to interact with a micro:bit while its program is running. For example, if the micro:bit picks up any radio messages, it will now be able to display them quickly in the terminal.
In computing, a terminal is “A combination of a keyboard and output device (such as a video display unit) by which data can be entered into or output from a computer or electronic communications system” according to Merriam Webster [1].
Large computers with numerous “terminals” connected to them used to be common in business and academics. Each terminal had a monitor and keyboard, and sometimes other devices.

With the advent of more sophisticated computers and networks, terminal emulator apps like the windows command prompt became common.
The “terminals” built into python.microbit.org and Mu are also considered computer terminal emulator apps, even though they are communicating with a microcontroller.
Hardware terminals are still in use today. For example, an ATM (Automated Teller Machine) is a terminal that’s connected to the bank’s system. At the ATM, a user can access their bank account and interact with a bank to withdraw or deposit money, check account balances, etc.
