    100BASE-T Switched LAN Integrating switching into the network enables network microsegmentation, which increases the total capacity and performance of the network. You can add 100 Mbps workgroups to the network and connect them to individual ports on the switch. For those networks that still support 10BASE-T workstations, an Ethernet switching hub provides configurable ports for 10 Mbps or 100 Mbps connections.
  • Page 40 By integrating the switching hub into the network that populates both 10 Mbps and 100 Mbps workstations, both groups experience the benefits of high-speed networking, even if they are not operating at the faster data transmission speed—both groups receive dedicated bandwidth (10 Mbps or 100 Mbps) that allows for quicker access to the servers and router connected to the switch.
