Before You Configure Your Module

What This Chapter Contains

This chapter describes some of the basics you should know about
Ethernet before you configure your 1756-ENBT module. The
following table describes where to find specific information in this
chapter.

Ethernet Protocols

On the most basic level, Ethernet is a wire or cable that connects
computers and peripheral devices so that they can communicate. The
actual wire used for the network is referred to as the network
“medium.” Beyond the physical medium, all Ethernet networks
support protocols that provide sophisticated data transfer and network
management functionality.

Transmission Control Protocol/Internet Protocol (TCP/IP)

Transmission Control Protocol/Internet Protocol (TCP/IP) is a
transport-layer protocol (TCP) and a network-layer protocol (IP)
commonly used in business environments for communication within
networks and across internetworks. The 1756-ENBT module uses
TCP/IP for “explicit” messaging, that is, messages in which time is not
a critical factor, such as uploading or downloading programs.
