# an installed TCP/IP Driver -> All operating systems come with one pre-installed in today's world!
# Access to a network that supports TCP/IP
# Access to a DNS Server (Domain Name System) -> This information is normally set and used from your Network Control Panel. It is either normally set statically or provided by a DHCP Server (Dynamic Host Configuration Protocol).

Optional:

# Access to a SMTP Server (Simple Mail Transport Protocol) -> If you plan to send e-mail you need access to an SMTP Server that can relay messages to a POP3 Server.

# Access to either a POP3 Server (Post Office Protocol) or an IMAP Server (Internet Messages Access Protocol) -> If you plan to receive e-mail you need access to a POP3 or an IMAP Server to fetch the messages from.
