Some questions regarding home networking?

Question

Alright, so I want to ask some questions regarding home networking.

1. What exactly does a port switch do? Here are examples.. http://homestore.cisco.com/searchresults.htm?keywords=switches+new&sortby=price

2. Can I hook up two ethernet cables to the port switch to get two internet connections on two different places? Such as my computer and the Ps3.

3. When I host games on the Ps3 with an ethernet cable directly from the modem to the Ps3 players don't lag, but when I use a router which is 30 ft away from the Ps3 players will lag if im the host. What can I do to fix that?

4. Do I need more bandwidth? My download speed is 7.4 Mbps and upload speed is 901 Kbps.

5. Can you give me any tips on when im the host why other players lag(including myself sometimes)?

Any help would be appreciated! Thanks.

1. A switch is used to extend the size of a network. This enables more devices to use the network, when there are no more ports for them to plug in to.



2. You can do this, yes. However, because your ISP only gives you one ip address to use, only one of the two devices will be able to use the internet at a time. If you want both devices to use the net at the same time, you would need to purchase a router. A router is used to share that one ip address among all the devices that are plugged into it. You would connect your modem to the router, the router to the switch, and the switch to all your devices.



3. When using the router, you need to forward certain ports in order to establish a better connection. Find out what ports the playstation network uses, and the ports that the game uses, and forward them to your ps3's ip address.



4. That's a decent speed for playing games and browsing the web. However, its a bit on the slow side for hosting.



5. See #3.

Answer 2

A switch allows a point-to-point connection between the host and the switch. So, if you had 5 hosts (computer, PS3, whatever) connected to the switch, they would all have access to the switch all of the time. HOWEVER, the switch would need to connect to a router/Gateway to access the Internet. The gateway can only be used to send one frame at a time (a frame is a packet encapsulated by your switch to move onto the wire). Therefore, if you had 5 hosts trying to access the medium at the same time, they would take turns: 1,2,3,4,5,1,2,3,4,5, etc. A switch will give you much LESS LAG than a Hub because a Hub rebroadcasts everything it hears.



Your best bet is to get a switch, and configure your router to listen only to that one switch. That will reduce overhead and lag.

Sorry to pay attention with regard to the attack. As for hacking your on the spot connection to devise the attack, it fairly is plausible yet distinctly unlikely. the two way you're able to shelter your community for different motives.
