Internet, And Networking?

OK, I'm going to try to put this as simple as I can, They are pretty basic questions.

Say you have a 5mb Internet connection. And you have 3 computers. And a Wireless G router.

At Computer 1, You have the modem and router there, You have the computer hooked into the router via ethernet.

Computer 2 and 3 are wireless, And used throughout the house.

Wireless G is 54mbs.. So upgrading to Wireless -N wont make the Internet faster, Right? Since the modem only puts out 5mbs?

Does the router split the wireless speed between the computers on the network? Or does each computer get its own 54mbs?

Basically this is my set-up that I have. I want to know how the Internet and router speed is shared between computers and etc, And What is the real point of Wireless N.. If Internet speeds don't even come close to that speed.

 

That's correct, no faster internet, the 5Mbps is the botleneck.

Normally the home LAN configuration is star, so only one computer can use the link at the time while interacting with one of the computers, then 54Mbps. However if all 3 computers are trying to reach internet at the same time, then the 5Mbps will be shared.

I would say, if you are looking just to get internet, then G even a or b is fine. But if you are looking to share multimedia or other data hungry applications among the computers at home, then go with N (300Mbps), and if you have money also go with N.

 

OK cool, Thanks.

Hmm, So If you have 4 computers.. And Xbox 360 all on connecting to the router wirelessly , How does does the router deal with that? And hypothetically, Say the Internet isn't the bottleneck. That 54mbs is shared? Or each device gets its own 54mbs? Or... Does it act like a processor, By that I mean, Switching between processes, Or devices. I'm not sure if I completely understand, Sorry.

 

I personally don't know enough about networking to answer that question, but I would think that bandwidth would be dynamically allocated between the computers by demand, with a max. bandwidth cap. for each computer. Thats an educated guess, btw.

 

Ethernet is not full duplex, which means you cannot have traffic in the cable in oposite directions at the same time. The residential WiFi as we all know it and use it, is not full duplex neither. Some do offer custom WiFi system using the mesh topology type using full dupplex, expensive products. You could also possibly use one channel to transmit and another channel to receive, this must be implemented with a special software though.

So the router will orchestrate the movement of the data using the IP addresses, and it will listen into the different lines prior to send data at 54Mbps. If the router is receving let's say from computer 1 and he just got a request from computer 2 to communicate with computer 1, then the router will finish receiving the data from line one and then proceed to continue with the data coming from computer 2 for computer 1...........................man, this is can get very complicated when trying to explain it.

 

So its seems this isn't as simple as I thought. I do mostly understand it then. First come first serve type of thing.. One process at a time? So with multiple computers using Internet at once it could get real complicated. Hmm. I wonder if you have a computer sending GB's to another to computer that takes awhile.. And another computer tries to access the Internet.. Will it have to wait to get its turn.. Or what?

I must not be the only one thinking about this.. If so..Guess I'm just not with it. If any of this doesn't make since or if I'm just not understanding you, Just say so.. I don't want to seem like a idiot.

 

Hahahaha, please don't worry that much, Internet is already much faster than us, so just setup your internet/network system and start enjoying it!

 

LOL, MY network is good to go for now.

I'm just one of those people that has to know how everything works.. I'm like that with Computers.. Cars.. ETC. And it doesn't help that I'm slightly OCD.

 

Listen I would like to retract myself with the full duplex thing, it would seems that ethernet is full duplex, so the router should be able to move data back and forth to an element in the network at the same speed (54Mbps), which means unless two computers want to contact the same computer, the 54Mbps will be in both directions, I hope this is clear. This doesn't impact your internet connection, though.

Sorry for inducing you in error, I answer too fast sometimes, so legacy ethernet used to be half dupplex, but not anymore. However is my understanding that WiFi is half duplex until someone tell us the contrary
