Machines within a domain will have names that include the domain name;for example, within sample.com domain i may have item1.sample.com,product.sample.com,anything.sample.com, etc...Those specific machine names are called hostnames. How does TCP/IP connect the English names--the hostnames--to the IP address? With Hosts,DNS & WINS...these are the process of converting a name to its corresponding IP address called "name resolution".
"Ping" is a TCP/IP utility to verify a connection within a TCP/IP network...and PING is not possible without enabling or using the TCP/IP protocol in the machine. IP address is required to identify a particular machine's IP address that can be configured statically or dynamically.

hostname maps to a ip address. Its easier to remember www.yahoo.com then its actual ip address. IP address identifies network id and host. Wins resolves netbios names(microsoft).

for windows, hostname mostly refers to the NetBIOS name that is assigned to it. this is assigned even if you don;t use Tcp/ip.

for linux machine it refers to the DNS hostname..which is not dependant on NETBIOS  as linux does not use NetBEUI
