Which pepper is typically part of salt and pepper? When people add salt and pepper to say chips, which pepper is it typically?

I had chicken and chips recently with pepper and it was black colour bits, would it have been black pepper?
It is typically black pepper.  The two common black varieties are Tellicherry and Malabar.  The peppercorn is the fruit of a flowering vine that is harvested when it is red, and ripe.  Each fruit contains one seed, which is dried and then packaged whole or ground.
