High-speed electronics in the switch automatically connect the end of one cable source port from a sending computer to the end of another cable destination port going to the receiving computer on a per packet basis.
Multiple connections like this can occur simultaneously. In a small network less than 30 users , a hub or collection of hubs can easily cope with the network traffic generated and is the ideal piece of equipment to use for connecting the users. When the network gets larger about 50 users , you may need to use a switch to divide the groups of hubs, to cut down the amount of unnecessary traffic being generated. If the traffic is constantly high, you may need to divide up the network using a switch.
Example of simple unmanaged switches can be found here: 8 port Fast Ethernet switch Nowadays switches are getting more sophisticated and to extend a distance limitations for UTP copper cables up to m , fiber is extensively used and many switches will have fiber SFP ports, like this 8 port SFP slot switch.
I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. The video goes from unbalanced, coaxial cable into a balun that sends the signal out on an RJ45 connector. I want to split that signal no data to 4 ports instead of one. Would a hub work for this?

The information provided in this post will help you better understand these networking devices in detail.
The company offer reliable network solutions at affordable prices. The company specializes in industrial ruggedized switches , fiber optic switches, fiber media converters , and more. A switch is a control unit that turns the flow of electricity on or off in a circuit. It may also be used to route information patterns in streaming electronic data sent over networks.
In the context of a network, a switch is a computer networking device that connects network segments. A switch is effectively 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.
Technically speaking, hubs operate using a broadcast model and switches operate using a virtual circuit model. When four computers are connected to a hub, for example, and two of those computers communicate with each other, hubs simply pass through all network traffic to each of the four computers. Switches, on the other hand, are capable of determining the destination of each individual traffic element such as an Ethernet frame and selectively forwarding data to the one computer that actually needs it.
By generating less network traffic in delivering messages, a switch performs better than a hub on busy networks. In the following video, hubs, switches, and routers are compared. A switch is used to connect various network segments. A network switch is a small hardware device that joins multiple computers together within one local area network LAN.
