Hongkong airport is one of the most important air traffic hubs in Asia.; The central part, usually cylindrical, of a wheel; the nave; A stake with a nail in it, used to mark a temporary point; a computer networking device connecting several ethernet ports. See switch; {n} the nave of a wheel; 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; In a 10-base-T network, each machine is connected to a hub, which is in turn connected to the network or to other hubs Physically, they are small boxes with 4 or more connecting sockets for 10-base-T wiring If a hub is connected to another hub, the hubs are said to be cascaded All machines on a hub see the packets for all machines on that hub, which may limit communication speed See Router; are cast; Equipment that serves as the centralized connection point for a network or portion thereof Hubs are used for multiplexing, multi-port bridging functions, switching and test access They can be either passive or active and are not considered to be part of the cabling infrastructure; a nebulous term, typically applied to a multiport repeater or concentrator consisting of a chassis with slots to be populated by cards, allowing it to be configured with various numbers and combinations of LAN ports Vendors of networking equipment often also have other types of devices that can be inserted in the slots such as terminal servers, bridges, routers, gateways, etc; The hilt of a weapon; A device that connects several other devices, usually in a star topology; A rough protuberance or projecting obstruction; as, a hub in the road; of Axle box; a device that splits one network cable into a set of separate cables, each connecting to a different computer; used in a local area network to create a small-scale network by connecting several computers together; the central part of a car wheel (or fan or propeller etc) through which the shaft or axle passes; A screw hob; the central part of a car wheel (or fan or propeller etc) through which the shaft or axle passes a center of activity or interest or commerce or transportation; a focal point around which events revolve; "the playground is the hub of parental supervision"; "the airport is the economic hub of the area; A central connection point Standard terminology for a device that connects multiple computers in a network; The hub of a wheel is the part at the centre; switching computer located in IDF "closet," joining a local network or a building to the backbone via a router / gateway; hubs join to network devices by means of "ports," each able to serve an IP address Departments in buildings with excess hub capacity can add devices by having IP addresses switched on; when all of a hub's ports are occupied, further expansion requires installation of another hub in the closet Hubs, like other switching units, don't have hard-drive storage the way regular computers do, but pass off information packets very rapidly, as in a super-efficient mailroom; A device that connects the cables from computers and other devices such as printers in an ethernet local area network Traditionally, hubs are used for star topology networks, but they are often used with other configurations to make it easy to add and remove computers without bringing down the network Smart hubs or switching hubs are often used to improve performance by managing traffic; A device that provides additional connections for other devices For example, a USB hub is a USB device that provides connections for additional USB devices; You can describe a place as a hub of an activity when it is a very important centre for that activity. The island's social hub is the Cafe Sport = centre; A device used to create a small-scale network by providing a common connection to all devices on the network; A concentrator that joins multiple clients by means of a single link to the rest of the LAN A hub has several ports to which clients are connected directly, and one or more ports that can be used to connect the hub to the backbone or to other active network components A hub functions as a multiport repeater; signals received on any port are immediately retransmitted to all other ports of the hub Hubs function at the physical layer of the OSI Reference Model; A block for scotching a wheel; A hardware device that contains multiple independent but connected modules of network and internetworking equipment Hubs can be active (where they repeat signals set to them) or passive (where they do not repeat but merely split signals sent through them) Hub may also refer to a repeater, bridge, switch, router, or any combination of these; device used to connect cables from more than two computers together Can be used for peer-to-peer and local-area networks Mentioned in: Types of Networks See also: network Pictures: Photo 1, Photo 2; Generally, a device connected to several other devices; specifically in computer networks, a repeater in the center of a network with star topology, usually with 10BaseT or 100BaseT Ethernet; A hardened, engraved steel punch for impressing a device upon a die, used in coining, etc; A device at the center of a star topology network Hubs can be active (where they repeat signals set to them) or passive (where they do not repeat but merely split signals sent through them) Hub may refer to a repeater, bridge, switch, router, or any combination of these; See Hob, 3; A hub is a network device that connects multiple computers on a LAN so they can communicate with one another, the rest of the network, and the Internet All users connected to a hub share the available network bandwidth (unlike a switch, which provides full bandwidth to each computer); 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; A hardware device that contains multiple independent but connected modules of network and internetwork equipment Hubs can be active (where they repeat signals sent through them) or passive (where they do not repeat but merely split signals sent through them); A goal or mark at which quoits, etc; A common connection point for devices in a network Hubs are commonly used to connect segments of a LAN A hub contains multiple ports When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets A passive hub serves simply as a conduit for the data, enabling it to go from one device (or segment) to another So-called intelligent hubs include additional features that enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub Intelligent hubs are also called manageable hubs A third type of hub, called a switching hub, actually reads the destination address of each packet and then forwards the packet to the correct port; a center of activity or interest or commerce or transportation; a focal point around which events revolve; "the playground is the hub of parental supervision"; "the airport is the economic hub of the area"; {i} center of a wheel into which the spokes are placed; central point around which other things revolve; center, focus; center of activity; (Computers) central part of a disk that is held by the drive in order to make it turn at the correct speed; (Computers) common point of connection for devices in a network; An unintelligent network device that sends one signal to all of the stations connected to it; Like an Airport Hub is a connection point for different airplanes, a network hub is a meeting place for multiple network connections There are large hubs that you, the user, never sees They hum away in equipment rooms keeping traffic flowing smoothly And there are smaller hubs that are in classrooms, dormitories and offices around campus These smaller hubs take the signal from a faceplate and split it into four or more separate connections Note that when a computer is off of a hub it is sharing it's network connection with all the other computers off of that hub so if you are off of a four port hub, your network connection will be one fourth the speed as if it were off the faceplate alone; A networking device with multiple ports that allows you to connect workstations, servers or peripherals to a network; A device that splits one network cable into a set of separate cables, each connecting to a different computer Used in a local area network to create a small-scale network by connecting several computers together; concentrator
