4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI. [3] [4]
Star topology in use in a network. A star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. [1] The star network is one of the most common computer network topologies.
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data ...
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1 ]
Additionally, Apple 10BASE2 cables terminate the network when no device is attached to them. Thus the number of mistakes that could be made hooking up a thinnet network is reduced considerably. Since any of these mistakes can disable the network segment, this presents a significant improvement. FriendlyNet equipment was expensive.
A typical service provider's network is a collection of switches and routers connected through optical fiber. The topology could be a ring, hub-and-spoke (star), or full or partial mesh. The network will also have a hierarchy: core, distribution (aggregation), and access.
The rules only apply to shared-medium 10 Mbit/s Ethernet segments connected by repeaters or repeater hubs (collisions domains) and FOIRL links. The rules do not apply to switched Ethernet because each port on a switch constitutes a separate collision domain. With mixed repeated and switched networks, the rule's scope ends at a switched port.
