| 373089 | 2005-07-19 23:36:00 | Can I ask a really dumbass question.... What are the fundamental differences between hubs / routers / switches? When would you use one over another? Sorry to link you to this (www.google.com etween%20hubs%20%2F%20routers%20%2F%20switches) . A switch is faster than a hub, around the same price or cheeper is most cases, both of these need no setup, just plug'n'play. A router is a device you can log into with it's ip address and configure what it will do, eg. setting DHCP, MAC address etc |

| 373090 | 2005-07-19 23:43:00 | Ya got me on the "switches" thing . . as that is usually used in parlance with . . . say . . . an "A & B" switch,; being used to handle two printers on the same puter without the network card . . . I think . . . I don't even use them . Now, the router ( . newegg . com/Product/Product . asp?Item=N82E16833124001&ATT=Network+Routers+Remo&CMP=KNC-goog13" target="_blank">www . newegg . com) is what the name entails, it "routes" signals to one place or another . . . kinda like a traffic cop . It allows for sharing a common hook-up with more than one device . Like using two 'puters on one line or one printer or one mainframe etc . It is usually self-powered and has nice lights and stuff on it to indicate traffic and the fact that it is either on or off . Routers are also a very good choice for dynamic IP and firewalls . They only allow your router to be seen on the net, hiding the equipment inside the circle of connections that it has . A hub ( . belkin . com/IWCatProductPage . process?Merchant_Id=&Product_Id=93743" target="_blank">catalog . belkin . com) is usually a lower-class device that lets some devices share a port to the motherboard . Like having a camera, a keyboard and a mouse and a hot shoe for a Palm or so . A hub is usually on a single computer, and allows opening a few more ports for devices to share . I like to use dynamic ones (with their own power supply) to keep the load off the PSU . Hubs can have nice lights too . . . hahah |

| 373091 | 2005-07-20 00:20:00 | Yep, a switch is essentially a network hub with a few bells and whistles like, better collision control, auto sensing (switches ports act to switch the signal automatically without having to use either a crossover or patch cable). Switches don't know or care what the traffic is, they just send it on. Routers do know and care what the traffic is, they send it to the correct client, the one that requests it (thats why on a shared WAN system, you don't get the other clients web pages or online game play). On a routerless shared connection, this is done via software in the gateway PC (the one connected directly to the modem) when ICS is used, hence ICS is nowhere near as efficient nor bug free as a router, which is why I don't like internal or USB DSL modems. Routers are used in a LAN in much the same way, the efficient direction of data to the requesting clients without bothering the whole network with the various wittering going on. Routers can be seperate from a modem, or in the case of most ADSL/DSL routers have a built in modem that communicates with the outside world (WAN). When a router has NAT capabilities, it "can" hide the client PC's IP addresses from the comminication with the outside world taking place at the modem, instead the outside world only sees the routers public IP, you (the client PC's) comminicate with the router via the private IP's. So NAT, acts a bit like a firewall, all traffic is routed through the router and only requests from the client PC's elicit responses (*cough* including malware requests from the clients, which is why it is not a true firewall). To communictae directly with the outside world, say for remote access or P2P, you have to open a hole/port, which can be very dangerous if not done properly for the exact task you wish. Modems are simply dumb devices that are used to convert the signal from the outside world into a form your PC (or router) can understand and vice versa In NZ, the cable modems that Telstra supply are only modems, the have no routing capabilities ot NAT. For security reasons, they should not be used without a NAT router or internet gateway and, by gateway, I don't mean a PC set up with MS ICS. This is also true for DSL modems that are not accompanied by a built in router. |
