Unlike hubs, switches are capable of inspecting the data packets as they are received, determining the source and destination device of that packet, and forwarding that packet appropriately.

A more sophisticated version of a hub that ensures each system only sees its own traffic.
A device that routes a call by selecting the paths or circuits to be used for transmission of information and establishing a connection.
A switch is a device the filters and forwards packets between LAN segments. It acts as a bridge giving each and every port the full bandwidth capability. If you have an 8-port 10/100 switch, then each port can be either 10 or 100 Mb, and each port is full-duplex. This means that there are no collisions, so no re-transmits, no back offs, full speed ahead and because it is full duplex, you can get full speed in both directions, or up to 200Mb throughput per port. Think of it like a high-speed 16-lane highway where each device gets, a full 2 lanes all to themselves, no speed limit. Each interface is its own collision domain, but the whole switch is one broadcast domain.

Some switches have fixed port speeds (10 Mbit/s or 100 Mbit/s) while others allow port speeds to be configured or autonegotiated.
A switch is used to connect two or more computers together as a network, similar to a hub. The advantage of a switch in comparison to a hub is that it will not run at a slower speed if there are people connected to the switch with slower network cards than others. Switches also keep a list of all the computers connected to it, so when a packet is sent to the switch to be relayed to another computer, the switch will forward the packet onto the correct computer and not every computer connected to it. The disadvantage of is that switches can be rather expensive, and are not really cost effective if you're running a small network, or if the network isn't dependant on speed. Larger networks that need high speeds would use switches rather than hubs.
Allows for a large network to maintain an effective data throughput by segmenting it into multiple parts, then passing traffic only to the segment that contains the destination host, thus eliminating traffic on the other segments.

In general, a switch is a simpler and faster mechanism than a router, which requires knowledge about the network and how to determine the route.

A network device that cross connects stations or LAN segments. Also known as a "frame switch," switches are available for Ethernet, Fast Ethernet, Token Ring and FDDI. ATM switches are generally considered in a category by themselves. Network switches are increasingly replacing shared media hubs in order to increase bandwidth. For example, a 16-port 100BaseT hub shares the total 100 Mbps bandwidth with all 16 attached nodes. By replacing the hub with a switch, each sender/receiver pair has the full 100 Mbps capacity. Each port on the switch can give full bandwidth to a single server or client station or it can be connected to a hub with several stations.

Sometimes called an intelligent hub, a switch checks a packet’s destination information and forwards it to only a single port. On larger networks, the trip between one switch and another is called a hop, and the time it takes for the switch to send a packet is called latency. The more packets a switch has to consider each second, the greater the latency and the longer the wait before each packet moves along to its next destination point.

Switches act as the center of a "star" topology, much like hubs. They have between 4 and 20+ ports. Internally, switches are different that hubs due to their intelligent design. Switches"remember" what device is attached to what port, and will relay packets only to the proper destination port. Because of this, all devices attached are able to utilize their maximum rated speed, be it 10 or 100Mbit/sec/port. This cleaver design makes switches more expensive, but in a busy network, switches can keep the traffic flowing. Switches have multiple collision domains (one for each switch port) and one broadcast domain.

A device that channels incoming data from any of multiple input ports to the specific output port that will take the data toward its intended destination. A switch helps to direct traffic more efficiently in a network and also allows computers to communicate with each other on a network.
A more advanced version of a HUB. It is a box that workstations hook up with.(See Hub)
Switches look nearly identical to hubs, but a switch generally contains more "intelligence" (and a slightly higher price tag) than a hub. Unlike hubs, switches are capable of inspecting the data packets as they are received, determining the source and destination device of that packet, and forwarding that packet appropriately. By delivering messages only to the connected device that it was intended for, switches conserve network bandwidth and offer generally better performance than hubs. A switch is effectively then, a higher-performance alternative to a hub. People tend to benefit from a switch over a hub if their home network has four or more computers, or if they want to use their home network for applications that generate significant amounts of network traffic, like multiplayer games or heavy music file sharing. In most other cases, home networkers will not notice an appreciable difference between a hub and switch (hubs do cost slightly less).

Similar to a hub, a switch allows for the connection of several workstations in a star configuration. Switches combine the functions of a Hub with those of a Bridge.: A switch is able to "memorize" the Ethernet address of a network station connected to a port and thus only forwards data packets destined for this address to the respective station. This does not apply to broadcast messages that are forwarded to all ports. (Switches and bridges differ in this regard, as bridges generally don't forward broadcast messages). In addition to switches for 100BaseTX (100Mbit/s) networks, there are also autosensing switches that automatically detect whether a connected terminal device operates at 10Mbit/s or 100Mbit/s. Autosensing switches thus allow for the integration of older 10BaseT devices into new 100BaseT networks.
a device which can make or break an electrical connection. In the context of ICT and learners with special educational needs it usually refers to an input device which at any time can be either on or off. Where a user’s physical movement is impaired, switches may be required to operate the computer. Many switches have been designed to meet the particular needs of disabled people.
An electrical or electronic device for opening and closing a current path.
A mechanical or electric device that is used to deliberately interrupt or alter the path of the current through the circuit.
1) In communications systems, a mechanical, electro-mechanical, or electronic device for making, breaking, or changing the connections in or among circuits. 2) Synonym for central office, switching center. 3) In communications systems, to transfer a connection from one circuit to another.
A switch is a device for changing the course (or flow) of a circuit. The prototypical model is a mechanical device (for example a railroad switch) which can be disconnected from one course and connected to another. The term "switch" typically refers to electrical power or electronic telecommunication circuits.
Switch was an American action-adventure, tongue-in-cheek and detective series that was broadcast on the CBS network for three seasons between September 9, 1975 and August 20, 1978, bumping the long-running Hawaii Five-O detective series to Friday nights. It was inspired by the 1973 movie The Sting. It was created by Glen A.
