Application software: This is the software you use to send e-mail, browse the World Wide Web, read
newsgroups, etc. These applications may require some configuration. Examples include the Eudora e-mail
client, and the web browsers Microsoft Internet Explorer and Netscape Navigator.
TCP/IP stack: This is the software that lets your PC or Macintosh communicate using Internet protocols.
TCP/IP stacks must be configured with some of the same information you used to configure the Netopia
R2020. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a built-in
TCP/IP stack. See "Configuring TCP/IP on Windows 95, 98, or NT computers" on page
computers use either MacTCP or Open Transport. See
page 3-13.
Ethernet: Ethernet hardware and software drivers enable your PC or Macintosh computer to communicate on
the LAN.
EtherTalk and LocalTalk: These are AppleTalk protocols used over Ethernet.
Once the Netopia R2020 is properly configured and connected to your LAN, PC and Macintosh computers that
have their required components in place will be able to connect to the Internet or other remote IP networks.
