Forgot login password on Mac

Hi,

Following tip could help your question.

1. Reboot your Mac while holding down the Command key and R. Keep holding the key combination until the loading bar appears.
2. Once in the Recovery Mode, select Terminal from the Utilities menu. ... 
3. Type “resetpassword” in the Terminal window and hit enter.

Is "reboot" the same as "restart" ?

utilities menu does not show Terminal ,hence how to resetpassword
