Differences between routers and switches [routers and switches] [router]
Q: What is the difference between a router and a switch?
Best Answer: PLEASE READ- Routers Switches and Hubs are NOT the samething. If you don't know what you are talking about please don't confuse people
Routers- Are devices in a network that will route data by actually using routing algorithms. They Actually think about what they should do. They usually used at the end of the network where the internet is.
Switches- Are kind of like hubs. They are used to connect alot of devices together. However unlike hubs they actually switch the data to the right ports. They are usually placed behind the router and have many ports for the Nods to connect to.
Hubs- Are used to connect devices to a network. But unlike switches it doesn't switch data. It send the data out ALL ports instead of switching it to the right one. This takes up network bandwith and that is why they are not really used.
Repeaters- Are used to stregthen a signal basicly. When you run cable pass the spefications then the singal will be weak and needed to streghten.

Re:You wouldn't need to use the uplink port. The uplink port exists because hubs/switches/routers and NICs use two different types of jacks and you have to use crossover cable to connect two of the same type, but an uplink port uses the same type as an NIC so you can connect it to another hub/switch/router without crossover cable.

Re:yep, so as long as the server did the routing, all you would need is a switch

Re:I would have a server.
I would have my computer, my old computer, my laptop, and my parents computer and the server.
The server would also be a print server and ftp server. I'd run the DSL into my Server, then from the Server to the uplink port on the switch right?

Re:Let me also try to explain the difference.
First, some background information. Every NIC (Network Interface Card) has a sort of serial number burned into it at the factory, called the MAC address. Also, a NIC has an IP address specified by either you or your ISP.
A switch is a simple device that switches packets based on their MAC address. For example, if there are five machines plugged into it, (all with different MAC addys, of course), and machine#1 wants to send data to machine#4, it puts #4's MAC address into the frame and sends it. The switch examines it and knows that machine#4 is destined to receive it. As simple as that.
A router uses IP addresses for routing — it examines the destination IP address and intelligently determines where to send it based on the ruleset it has been given by the network administrator.

Re:switch just links your computers together and makes the network basically. a router will interface with your cable modem or adsl modem and route packets so that all the computer on your lan have internet access even though you only have one ip address and modem

Re:well, a router is like an advanced switch. It allows you to connect multiple computers to a cable modem / dsl line while only needing 1 IP. So instead of buying multiple IP's , the router "routes" packets of data to each computer, effectively allowing them to "hide" behind the router. So from the outside word, all you would see is the router, and not all the other computers.
