Accessing a Linux system inside a network: is it via hostname or netbios name?

Assuming a Linux system has both hostname (/etc/hostname) and NetBIOS (/etc/samba/smb.config) enabled. My questions are: 1. Are these 2 names synchronized somehow by default settings? (for example, after installing the samba, does the netbios name = something setting get changed in (/etc/samba/smb.config) to the same value of hostname (/etc/hostname)?) 2. When the Linux system is pinged by its name, Would it be looked up by the name in its /etc/hostname or /etc/samba/smb.config?
