I stand to be corrected, but I think basically a hub is a dumb device that connects a network together. All packets are sent to every machine on the network and it is down to the individual devices to listen out for their own packets. A router is an intelligent device that routes packets to the correct device on the network, so the individual devices only their own packets and don't have to filter out packets for every other networked machine. > 2) Are all ROUTERS 4-port, or do they come 2-port or even more than > 4? Not sure, but I think you could get any number of ports - demand and supply dictates that small routers in fancy plastic cases with 4 ports are more mass-produced for home networks and large rack devices are produced for industry! > 3) Can HUBS really be daisy-chained to as many as 200 ports? They can be daisy-chained, but I don't know what the limit is on ports. > 4) Can ROUTERS be daisy-chained at all? Pass!

From: Erick on 10 Jan 2006 08:35 To put in simple terms, you must first have a router if planning on using broadband on multiple computers. The router determines what is coming in and where it's going, thus the term router. A hub, however, is like a busy intersection with no traffic lights: the traffic goes wherever it wants to go with no control.

A hub sends incoming traffic out on all ports. A router segregates a LAN from a WAN. They are only related in that they are often used in the same lan but each for a different purpose. However, many modern consumer-grade routers also have a switch built in, and while that is very very common, it's not necessarily inherant in a device being a 'router'. The switch supercedes a hub as it can direct traffic to the appropriate destination instead of repeating it on all outbound ports, which would consumer more bandwidth- not a problem if you had plenty of spare banddwidth but a problem if you didn't. > >2) Are all ROUTERS 4-port, or do they come 2-port or even more than >4? No, old routers or corporate grade only have 1 port that connects to the LAN, and 1 to the WAN. As for consumer grade routers, 4 or 5 port switches integral are the most common, because that happens to be what the typical core (cost effective) chipsets used in them, support. When a router has 8 port switch, it typically means doubling up on some internal components to achieve this, which raises costs. It also seems of limited benefit to a consumer lan because most wouldn't have so many systems nearby, though they could always add a hub or switch if they did. I don't recall seeing any 2 port, but it's possible they could only use 2 (LAN) ports. If you are considering purchase of one, just look up the manufacturer's specs which should clearly detail this feature. > >3) Can HUBS really be daisy-chained to as many as 200 ports? Yes, but with that many (assuming you wanted to use a lot of them) it would be prudent to use switches instead, at least in the centers of star configuration networks to minimize wasted bandwidth, keep traffic as isolated as economically possible (thinking in terms of consumer grade equipment, as products with over (roughly) 16 ports start to climb in price quickly), even after 4 or 8 ports the price starts to skyrocket. > >4) Can ROUTERS be daisy-chained at all? Yes, you could link them as only switches (when they have a switch built in as most modern consumer-grade do) without any consideration that they're also routers (except to disable certain router features that are redundant like DHCP service) since you would then be ignoring that they're routers too, OR you can further segregate sub-lans from WANs containing other local (LANs) if you had a specific need to do so, which then means using the router fuctionality of one unit for each segregated LAN. In other words, the typical way to configure these parts is to first determine what the network needs are, define that clearly then choose the parts and parts-configuration necessary to accomdate.
