GLOSSARY 3

Hub A device used to provide connectivity between network devices. Hubs perform the basic repeater functions of restorating signal amplitude and timing, detecting collisions, and broadcasting signals to lower-level hubs and network devices.

MAC Media Access Control. The data link sublayer that is responsible for transferring data to and from the physical layer.

MIB Management Information Base. A logical naming of all information resources residing in a network and pertinent to the network’s management. Simple Network Management Protocol (SNMP) management uses a set of standard MIBs known as MIB II and other standard MIBs for FDDI, Ethernet, etc. In addition, vendors write proprietary MIB extensions for SNMP management of particular devices.

Partition A repeater function that isolates a particular port from the network because of an excessive number of collisions. Once the problem causing the collisions is corrected, the port is reactivated.

Repeater A device that extends the length, topology, or interconnectivity of the physical medium beyond that imposed by a single segment, up to the maximum allowable end-to-end trunk transmission line length. Repeaters perform the basic actions of restoring signal amplitude, waveform, and timing applied to normal data and collision signals. See also Hub.

SNMP Simple Network Management Protocol. A network monitoring protocol for TCP/IP-based networks. It is a simple request/response protocol used to communicate management information between the network management station and the agent residing in network elements. The protocol does not define the objects that can be managed. (The MIB defines manageable objects.) SNMP can be used with any network management variable that can be inspected and altered.

Standard Ethernet A 0.4-inch diameter cable comprised of two foil shields and two braids over cable copper wire. It requires an external transceiver cable or N-series to BNC series

adapter. It is also called thick Ethernet cable. See also thin Ethernet cable.

STP Shielded twisted-pair. Shielded four-conductor electrical cable that offers high-speed transmission for long distances.

100 TX specifications

The 3Com 100 TX is a leading networking device that revolutionized Ethernet connectivity in both small and large enterprise environments. As a part of the 3Com family, this device was designed to provide reliable and efficient network performance, supporting the growing demands of networking technologies in the late 1990s and early 2000s.

One of the main features of the 3Com 100 TX is its compliance with the 100BASE-TX standard, enabling rapid data rates of up to 100 Mbps. This makes it ideal for high-speed local area networks (LANs) that require swift data transfer among connected devices. The device effectively accommodates the increasing bandwidth needs brought on by resource-heavy applications and the proliferation of internet services.

The 3Com 100 TX employs a Category 5 cabling system, which is crucial in achieving optimal performance. This cabling type allows for improved signal quality and reduced crosstalk, particularly over longer distances. By integrating this technology, the 3Com 100 TX can maintain a reliable point-to-point connection, ensuring minimal packet loss and superior data integrity.

Another significant characteristic of the 3Com 100 TX is its innovative design, which facilitates easy installation and integration into existing network infrastructures. The device features auto-negotiation capabilities, allowing it to automatically detect and adapt to the speed and duplex settings of connected devices. This plug-and-play functionality minimizes configuration time, making it user-friendly for both seasoned network engineers and those new to networking.

In terms of network management, 3Com incorporated various tools to help administrators monitor and troubleshoot network performance efficiently. The device includes diagnostic indicators such as Link and Activity LEDs, providing real-time feedback on connection statuses. This aids in quick identification of potential issues or downtime, ensuring network reliability.

Overall, the 3Com 100 TX remains a noteworthy component in the evolution of Ethernet technology. Its exceptional speed, flexible cabling compatibility, and user-oriented design make it an enduring choice for businesses seeking to enhance their network infrastructure. By investing in such devices, organizations can achieve optimal connectivity, laying a strong foundation for a robust digital ecosystem.
