About Network Hubs

Network hubs serve as the central location for attaching wires to workstations. They can be passive, where there is no amplification of the signals; or active, where the network hubs are used like repeaters to provide an extension of the cable that connects to a workstation.  Protocol, port, and features are the most important specifications to consider when searching for network hubs.

Protocol is the fundamental mechanism for network communications via network hubs. They specify the software attributes of data communications, including the structure of a packet and the information contained in it. Protocols may also prescribe all or some of the operational characteristics of the hardware on which they will run. Popular network protocols include IPX and TCP/IP Additional protocols available for network hubs include ATM, CANbus, ControlNet, DeviceNet, ARCNET, 10 Base-2 Ethernet, 10/100 Ethernet, 10Base-T Ethernet, Fast Ethernet, Gigabit, Ethernet, Fibre Channel, FDDI, Fieldbus, Frame Relay, INTERBUS, ISDN, PROFIBUS, SONET, Token Ring, and xDSL.

Products & Services Related to Network Hubs

Network Equipment
Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).
Network Firewalls
Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.
Network Routers
Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.
Network Switches
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.
Network Transceivers
Network transceivers, short for transmitter-receiver, are devices that both transmit and receive analog or digital signals.
Networking Repeaters
Networking repeaters regenerate incoming electrical, wireless or optical signals to preserve signal integrity and extend the distance over which data can travel. They are often used to connect cable segments in IEEE 802.3 networks.
VoIP and IP Telephony
VoIP and IP telephony allows PC users to make phone calls over the Internet or other packet networks via gateways and standard telephones.
