		Active hubs do the same job that passive hubs do but they also work as repeaters to regenerate the signal that they have recieved.
		By implementing an active hub, you can concentrate the signals to be forwarded to another hub, switch, bridge, or router while regenerating and strengthening the signal at the same time.
		Reguardless of the type of hub that one requires for thier particular configuration, rackmount hubs allow an extended manageablilty and convienience especially in an environment where the hub is providing cabling services for rackmounted routers, bridges, or servers.

	What is difference between active hub and passive hub? (Site not responding. Last check: 2007-09-19)
		Since the market for hubs was quite big, there were a few different types of hubs introduced, covering different market needs and giving the buyer a wider range of similar products to choose from, depending on what exactly he required.
		Active hubs are a little smarter than the passive hubs we saw.
		All You might also come across the term "concentrators" which are basically active hubs, concentrating and strengthening a signal as it enters and exits the hub.

	ITNW 2313 - Exploring ARCnet Specifications
		A port on an active hub can be connected to a port on another active device (such as another active hub or an NIC) or to a passive hub.
		Active hubs are required to extend the network for long distances and to configure networks that have more than four nodes.
		Passive hubs are used as an economical means of splitting a port on an active hub to support three devices.

	Hubs are essentially just multiport repeaters (Site not responding. Last check: 2007-09-19)
		An active hub functions in the same way as a repeater, except that it must also broadcast the regenerated signals to all connected network segments rather than forwarding them to just one segment.
		Hubs range in size from four ports up to several hundred and are specific to the network type.
		In addition to ports for connecting to computers, even very inexpensive hubs generally have an uplink port that enables the hub to be connected directly to another hub using a standard patch cable to create larger networks.

	Eurotherm/Barber-Colman S9576, ALIN Compact Active Hubs
		The integrity of an ALIN segment may be protected against the failure of a cable by the use of an active hub as a buffer/network isolator.
		The active hub may be considered a buffer/isolator supporting multiple network connections using either twisted-pair or fiber-optic cables.
		The twisted pair port on the active hub appears as a balanced twisted-pair port with a high input impedance.

	-=[ Think Quest '05 ]=-
		Using a hub changes the network topology from a linear bus, where each device plugs directly into the wire, to a star.
		With hubs, data arriving over the cables to a hub port is electrically repeated on all the other ports connected to the same network segment, except for the port on which the data was sent.
		Intelligent hubs are more expensive than active hubs, but are useful in troubleshooting situations.

	Upgrading and Repairing Networks -- Ch 13 -- Hubs: Dumb, Smart, Switching, and Otherwise
		Active hubs are often called concentrators (either because they concentrate and thus strengthen the signal or because they concentrate the capabilities of an entire LAN into a box--I've heard both theories).
		Although most hubs are stand-alone machines with their own chassis, they don't have to be--a few vendors sell hub cards that you can put in your file server (for small networks) or a dedicated hub machine (for larger networks) and thus lower the cost of a star topology.
		Essentially, card hubs are a good idea for a very specific set of conditions (a small network that wants the management ease of a star topology but can't afford a stand-alone hub), but beyond that set of circumstances a stand-alone hub probably will work better.

	Introduction to Hubs
		A hub is a special type of network device that can be used in home and small business networks.
		Basically, a hub is not interested in the data that is passed through them.
		Intelligent hubs are active hubs with added extra features that are particular to the use of the network.

	Configuring VPN Settings
		A hub's internal networks are a group of subnets that reside behind the hub but are not directly connected to the inside interfaces on that hub.
		A hub's inside interfaces are physical interfaces or subinterfaces on the hub that connect the hub with the hub side networks.
		The subnets that are directly connected to the hub's inside interfaces, with no intermediary network device, are known as "attached networks." The subnets located beyond the attached networks, that are connected to the attached networks through an intermediary router, are known as "internal networks." See Specifying a Hub's Internal Networks.

		Also note that one of the biggest attractions of the star topology network is that, if a cable run from a workstation to the hub fails, only that workstation is effected, it does not effect the rest of the network.
		A switch is a networking device that combines the network connectivity of a hub with additional bandwidth and intelligence.
		This is often used to connect hubs on different floors of a building.

	Sunopsis Active Integration Platform (Site not responding. Last check: 2007-09-19)
		The Active Integration Platform is built around a persistent data and event database – the Active Integration Hub (AIH) – which essentially captures the superset of all data and business events contained in all systems linked by the Active Integration Platform.
		Since the Active Integration Hub always represents a stable state of the integrated applications, it can also be viewed as an integrated representation of the Information System and accessed as such.
		In turn, changes to the Active Integration Hub are pushed to subscriber applications which are consumers of events, after transformation from the Common Format to the applications’ native formats.

		A hub is a piece of equipment that provides a connection point for a group of computers and peripherals, and it works on a low-level network protocol layer.
		Hubs are commonly used in LANs (local-area networks), where two or more computers are sharing the same devices, such as printers, Internet connection, scanners, and so on.
		Data is sent to the hub, which then distributes it to other areas on the network.
