My Mac's name in terminal is off

Question

apples-MacBook-Pro:Desktop Parth$
Why does it say apples-MacBook-Pro here? Shouldn't it say Parths-MacBook-Pro since my account name is Parth?
Is this correct or my system prefs are wrong? Just curious!
Edit:
Recently my Mac was formatted and after that the service sender guys created an account whose name was apple
I did add a new account with name Parth but still it shows apples-MacBook-Pro!! I checked and before the formatting it used to say Parts-MacBook-Pro:

Answer 1

That is your computer/Mac hostname

You could change it by going to System Preferences -> Sharing In the Computer Name settings, press the Edit Button

For further control that text at terminal. It is about setting the environment variable PS1

You could check your current PS1 value by running the command echo $PS1

Here is the reference about how and what could you set to your PS1
