Chapter 1: Introduction
r
This newly redesigned Linksys 5-, 8-, or 16-Port 10/100 Switch can significantly increase your network traffic’s speed. A switch serves the same function
as a hub in a network design—tying your network equipment together. But
unlike a simple-minded hub which divides the network’s bandwidth among all
the attached devices, a switch delivers full network speeds at each port.
Installing this cost-effective 5-, 8-, or 16-Port 10/100 Switch can potentially
increase your network speed by f ive, eight, or sixteen times!
It's the perfect way of integrating 10Mbps Ethernet and 100Mbps Fast Ethernet
devices, too. All ports are auto speed negotiating, and have automatic
MDI/MDI-X crossover detection, so you don’t have to worry about the cable
type. Each port independently negotiates for best speed and half- or full-duplex
mode, for up to 200Mbps of bandwidth per port. Fast store-and-forward switching prevents damaged packets from being passed on into the network.
The new, ultra-compact case design is sure to fit into your workgroup environment. Let the Linksys 5, 8-, or 16-Port 10/100 Switch kick your 10/100
network into high gear.
