Local area network standards

A local area network (LAN) is a communications system that allows the interconnection and sharing of resources between independent devices within a moderately sized geographic area.

Distributed data interface networks
A Fiber Distributed Data Interface (FDDI) is an optical fiber-based local area network (LAN) that uses the American National Standards Institute (ANSI) 3T9.5 standard for a media access control (MAC) protocol of token ring.
Ethernet networks
Ethernet is one type of local area network (LAN) topology that the i5/OS operating system supports. i5/OS Ethernet provides support for the Digital Equipment Corporation, Intel Corporation, and Xerox standard (Ethernet Version 2) and the IEEE 802.3 standard.
Token-ring networks
A token-ring network is a local area network (LAN) topology that sends data in one direction throughout a specified number of locations by using a token.
Wireless networks
The more mobile your employees are, the more you should consider a wireless network. The portable transaction computers (PTCs) make the direct connection between the office and offsite locations possible.
