A networking hub is a device that relays data communication. It sends data packets to all devices that are within a network, regardless of any MAC addresses it contained.
how does computer send data through serial port?
A "Hub".
at the physical layer ,hub can support little in the way of sophisticated networking. hubs do not read any data passing through them and are not aware of there source and destination.
a hub
Hi all,The main differance between the a switch and Hub is the hub will disribute the data among the system.(For eg: a hub have 8 port and in each system is connected and if a a system send a data of 100 mbps then all the system will share the data among themself and by the end system 100/8 it will send or get around 12.5mbps.) but incase of switch is won't do such things instead it will send the data as the same amount as it sends from the source.
None. Unlike Wireless switch's and hubs will send data to anything physically connected to them. = =
Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports. That makes the hub inefficient - in a hub, only one computer can transmit at a time.Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports.

A hub is used in network situations. It provides a central connection for multiple media segments. The hub repeats a signal received on one port and send them to ALL other ports. A hub operates in half duplex mode, meaning that devices can only send when no other devices are sending data. Use a switch when possible.
Switch because it is at least a little intelligent and can send data packets to the correct port.-----------A switch also regenerates the network signal, where a hub does not.
Computer network Polling is where a client server or Network Hub polls each computer for data. Data can only be sent when the particular computer is polled. If the computer has data to send but is not polled at that time, the data has to be stored until it can be sent. ^_^ JunkCollector ^_^
All data on that network segment.
SMTP and HUB ports!
Hubs (As in the networking device) are considered to be a "dumb" device so to speak. When a packet is sent to a computer connected to a hub with other computers attached, it will forward the packet to EVERY computer connected to it. The issues involved with this is data collisions, if a computer is trying to send out data to something on a different network, while the hub is trying to send a packet there will be a collision. These have the tendency to slow the network down and the data that collided is lost. Since there is so much traffic being sent a hub will just keep forwarding what it is sent to every computer attached. This can drain network resources, which intern slows down the network for others. So it's better to use a switch in most cases, as they avoid many of the issues hubs face.

The HUB model posit communication as an interactive and interpretative process. Messages are sent by the source and the receiver get it, interpret it and send out feedback.
