A hub is used to connect two or more computers together as a network, similar to a switch. The disadvantage of a hub in comparison to a switch is that a hub only allows the network to run as fast as the slowest computer connected to it. For example: if you have four computers in a network with two of them using 10Mbps network cards and two with 100Mbps network cards, then the entire network will run at 10Mbps. When a packet is sent to a hub intended for another computer, the hub would relay that packet to every other computer connected to the hub. The advantage is that a hub is usually cheaper than a switch, so it is often preferred for smaller networks that don't rely on speed.

A hub is a device which allows you to connect computers and other devices together to form a LAN. When a hub receives packets from a computer or other device, it repeats the packets to all of the devices connected to its ports. Hubs transmit "frames." All workstations receive the frames from hubs, but only the devices that correspond to the destination devices' address respond--all other devices simply ignore the packets. The process of examining, responding to, and ignoring packets is handled automatically by software running on the computers connected to the hub. In practice, when several computers are connected to the same hub, they can communicate with each other, sharing files and printers.

Hubs act as the center of a "star" topology. They have between 4 and 20+ ports. Internally, hubs are "dumb" devices that just resend information they receive. All devices attached utilize a part of the rated speed, be it 10 or 100Mbit/sec. Hubs know nothing about a packet's destination. Therefore, hubs are generally the cheapest connecting device in a star topography, although for a busier network, switches are more robust. Hubs have one collision domain and one broadcast domain.
(1)A device connected to several other devices. In ARCnet, a hub is used to connect several computers together. In a message handling service, a hub is used for the transfer of messages across the network. An Ethernet hub is basically a "collapsed network-in-a-box" with a number of ports for the connected devices.(2) Communications center, (3) Major routing station for connecting channels, (4) DDS connecting center

As a network product, a hub may include a group of modem cards for dial-in users, a gateway card for connections to a Local Area Network (LAN), and a connection to a line.
Network component that provides a central location to connect cables.
The central point of a network that allows computers to share resources such as data or access to printers and the Internet.
Hardware in a fixed location that connects different users to a network via multiple ports on the hub.
In internet technology, a hub is a device that connects several networks or machines together. In the context of eBusiness, "hub" usually refers to a central Repository or private Exchange. It is a web-based solution that makes it easy for trading partners to exchange data necessary to negotiate and complete eCommerce transactions.
A simple device for connecting computers equipped with network adapters together.
An FC_AL switching device that allows multiple servers and targets such as storage systems to connect at a central point. A single hub configuration appears as a single loop.
A device that provides a central point of cable connection.
The Cisco 800 series routers provide a HUB/NO HUB button. This button is associated with the Ethernet port on Cisco 801 and Cisco 802 routers and with Ethernet port Ø on Cisco 803 and Cisco 804 routers. The setting of this button determines the cable type (straight-through or crossover) that you use to connect an Ethernet device. This button is the equivalent of the TO HUB/TO PC button on the Cisco 802 IDSL and Cisco 804 IDSL routers.
Acts like an adapter on the network that allows extra devices to be connected to the network. For example attaching a 7-port USB hub to a computer allows an additional 7 USB devices to be connected.
A device that connects several computers to a network.
A piece of hardware that receives and forwards data between computers or other devices on a network. See also: Router, Switch.
The satellite central earth station through which all traffic is routed in a star configuration VSAT network. The hub is the master station through which all communications to, from and between VSATs must flow. Back to the TOP
Part of the network infrastructure. Basically a box that is connected to the server with one cable on one end, and out of the other end of the box come 8 or 16 cables that go to workstations.
The centre of a star topology network or cabling system. A multi-node network topology, that has a central multiplexer with many nodes feeding into and through. The other nodes do not usually directly interconnect. LAN hubs are increasingly popular with the growth of structured cabling and the need for LAN management.
A device that extends the maximum physical length of a network by cleaning and retransmitting signals among network segments. A hub provides the central connecting point in a star network topology. Also called a multiport repeater.
A common point of connection for computers and devices in a network.
Network device that joins all the network devices centrally in a star configuration.
A device that serves as a common connection point for multiple devices on a network. There are several different types of hubs, but in general each receives and sends signals to all the devices connected to it.
A device that connects several devices or computers together on a local area network.
The central transhipment point in a transport structure. The stretches between hubs are sometimes referred to as trunks, or spokes, thus giving rise to the term ‘ hub and spoke'.
A signal distribution point for part of an overall system. Larger cable systems are often served by multiple hub sites, with each hub in turn linked to the main headend with a transportation link such as fiber optics, coaxial supertrunk, or microwave. A hardware device that interconnects computers on a Local Area Network and acts as a central distribution point for the communications lines.
A hub, also referred to as a star coupler, allows for the connection of multiple network stations in a star configuration. Data packets received at a port are forwarded to all other ports. Apart from hubs for 10BaseT (10Mbit/s) and 100BaseTX (100Mbit/s), there are also autosensing hubs that automatically detect whether a connected terminal device operates at 10Mbit/s or 100Mbit/s. By means of autosensing hubs, it is thus possible to integrate older 10BaseT devices into new 100BaseT networks.
A device connected to several other devices. In ARCnet, a hub isused to connect several computers together. In a message handlingservice, a hub is used for the transfer of messages across thenetwork.[Source: MALAMUD] Hypermedia
A device connected to several other devices. Example, USB hub is plugged into the USB port on your computer. Now that the hub is plugged in, you have extra ports.
A hardware device with many ports to which computers and peripheral devices are attached. There are three types of hubs: modular hubs, which have a chassis with several slots for various types of computer cards: standalone hubs, which contain a fixed number of ports; and stackable hubs, which allow several to be connected to serve as a single unit.
Hardware used to network computers together (usually over an Ethernet connection). Its a small box with five or more RJ-45 connectors that accept cables from individual computers.
A physical layer device, connected to other devices, that restores a signal's amplitude and timing for transfer across a network. Known as a repeater in most IEEE 802.3 standards and also called a concentrator. The hub usually resides at the core of a star topology network and is used for the transfer of messages. Hubs provide Ethernet, token ring, and/or FDDI functions; accept host, internetworking, and network management modules; and provide retiming/repeater, bridging, and/or network management functionality. A typical hub has multiple user ports to which computers and peripheral devices are attached. See also topology.
