Using a hub is the least high-priced way to associate computers together. A hub is a easy gismo that passes on information packets from one computer to all the other computers it networked with. Each computer receives the information and deciphers if it was meant for it or not.
This works fine for networking a few computers that won't be transferring large packets of information. information packets must be transferred one at a time straight through the hub or collisions occur. When any computers try transferring information at the same time, it slows down the replacement rate for everybody on the Lan (local area network).
A hub is a easy piece of equipment. It serves as a replacement gismo that simply take information received straight through one port and sends it out straight through all the other ports. It has a layer one function for transferring information.
A hub uses a broadcast model. When using a hub, if whatever on the network is downloading a large file, it slows down everyone's speed of transferring information. If you have four or more computers in your home and do a lot of multi-player gaming, you will consideration a valuable difference between using a hub and a switch.
When connecting any computers, a lot of information traffic is passed back and forth straight through a hub, sometimes creating information traffic jams. A switch in the network will cut down on the unnecessary information traffic. The switch has the capability to only pass on only the information addressed to that singular computer.
With an Ethernet switch, the network is divided into manifold bridges and each computer is assigned it's own Ethernet port. When packets of information are received, the switch determines which computer the packet is to be delivered to and sends on the information only to that computer. manifold connections can occur at the same time without valuable loss of speed.
We previously mentioned that hubs are carefully as a level one function for transferring information. Switches are carefully to be a level two and above and can handle most networking needs. A router is a switch with a level 3 function that can recapitulate between separate types of connections, allowing you to associate to the internet (Wan) as well as to your own network (Lan).
On the outside, both hubs and switches look pretty much alike, but their function differs greatly. An Ethernet switch will cost more than a hub, since it has the added intelligence a hub lacks. You will need to rule which is the best selection for your network.
