[. . . ] Also known as line speed between network segments. BOOTP ­ The BOOTP protocol allows you to automatically map an IP address to a given MAC address each time a device is started. In addition, the protocol can assign the subnet mask and default gateway to a device. bridge ­ A device that interconnects local or remote networks no matter what higher level protocols are involved. Bridges form a single logical network, centralizing network administration. broadcast ­ A message sent to all destination devices on the network. broadcast storm ­ Multiple simultaneous broadcasts that typically absorb available network bandwidth and can cause network failure. console port ­ The port on the switch accepting a terminal or modem connector. It changes the parallel arrangement of data within computers to the serial form used on data transmission links. This port is most often used for dedicated local management. CSMA/CD ­ Channel access method used by Ethernet and IEEE 802. 3 standards in which devices transmit only after finding the data channel clear for some period of time. When two devices transmit simultaneously, a collision occurs and the colliding devices delay their retransmissions for a random amount of time. data center switching ­ The point of aggregation within a corporate network where a switch provides highperformance access to server farms, a high-speed backbone connection and a control point for network management and security. Ethernet ­ A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet networks operate at 10Mbps using CSMA/CD to run over cabling. Fast Ethernet ­ 100Mbps technology based on the Ethernet/CD network access method. Flow Control ­ (IEEE 802. 3z) A means of holding packets back at the transmit port of the connected end station. Prevents packet loss at a congested switch port. forwarding The process of sending a packet toward its destination by an internetworking device. full duplex ­ A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. half duplex ­ A system that allows packets to be transmitted and received, but not at the same time. Contrasts with full duplex. 13 D-Link DES-1048G Unmanaged Layer 2 Ethernet Switch IP address ­ Internet Protocol address.
