Grouping customers according to homogeneous attributes. For example, an automobile manufacturer with a full line of vehicles uses segmentation by income level in planning the marketing of its products. Small, entry-level vehicles are marketed to individuals and families with modest incomes, while wealthy individuals are market targets for the firm's luxury vehicles. Segmentation allows a business to focus its marketing where it will be most productive.

- The act of dividing something into smaller units.
- In local area networks (LANs), the act of dividing a LAN into smaller physical units on a geographical basis through filtering bridges, hubs, switches, or routers. Segmentation relieves congestion by limiting the scope of broadcast messages and by confining unicast and multicast traffic to the segment or segments in the physical path between the originating device and each destination device. See also broadcast, filtering bridge, hub, LAN, multicast, switch, router, unicast.
- In asynchronous transfer mode (ATM), the process of dividing an incoming data unit -such as a block, frame, or packet -- into cells. As the cells exit the ATM network, they are reassembled in order to reconstitute the original block, frame, or packet. The entire process is known as segmentation and reassembly (SAR). See also ATM, block, cell, frame, packet, and SAR.
- In packet networks, the breaking of large packets into multiple smaller packets (or IP frames) to meet limits on packet length. Transmission Control Protocol (TCP), for example supports the segmentation of files prior to transmission, and their reassembly upon receipt. See also frame, IP, packet, segment, and TCP.
