SMC Networks SMC9452TX-1 manual

Fast Ethernet: A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method.

Full Duplex: Transmission method that allows two network devices to transmit and receive concurrently, effectively doubling the bandwidth of that link.

Gigabit Ethernet: A 1000 Mbps network communication system based on Ethernet and the CSMA/CD access method.

Hub: Central connection device for shared media in a star topology. It may add nothing to the transmission (passive hub) or may contain electronics that regenerate signals to boost strength as well as monitor activity (active/intelligent hub). Hubs may be added to bus topologies; for example, a hub can turn an Ethernet network into a star topology to improve troubleshooting.

IEEE: Institute of Electrical and Electronic Engineers.

IEEE 802.3: Defines carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications.

IEEE 802.3u: Defines CSMA/CD access method and physical layer specifications for 100BASE-TX Fast Ethernet.

IEEE 802.3ab: Defines CSMA/CD access method and physical layer specifications for 1000BASE-T Gigabit Ethernet over Category 5 UTP cable.

IP Address: IP stands for Internet Protocol. An IP address consists of a series of four numbers separated by

periods, which identifies a single, unique Internet computer host. Example: 192.34.45.8.

ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals and other businesses or organizations.

Local Area Network (LAN): A group of interconnected computer and support devices. It is made up of servers, workstations, a network operating system and a communications link. Servers are high-speed machines that hold programs and data shared by network users. The workstations (clients) are the users' personal computers, which perform stand-alone processing and access the network servers as required.

LAN Segment: Separate LAN or collision domain.

LED: Light emitting diode is used for monitoring a device or network condition.

MAC Address: MAC (Media Access Control) A MAC address is the hardware address of a device connected to a network.

Media Access Control (MAC): A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.
