Switch Bandwidth
We have a network of 4 computers using a switch and one broadband connection of 1mbps. I wanted to know a few things.
1. Does this mean each of us gets 1mb every second, or does each of us get 1mb for 1/4 second(since my understanding is that access to the bandwidth is "switched" among the four comps very fast.
2.Does it matter if we are all downloaading movies or playing online games. I mean, does the downloading by one user affect the speed of the other users in my house?
3. If a computer is connected to the switch but is not accessing the internet, does it mean when it is his turn, the bandwidth is wasted?
Thanks, and I would really appreciate a detailed yet clear and easy to understand answer. I will not hesitate to increase the points if I find the answer given worthy of it.
Thanks in advance.

You'd have to have a managed switch to assign bandwidth. So, some will get higher bandwidth than others. If you want a managed switch, you'll need a layer 3; and that's a whole other game then.
# Is this a shared line from your ISP? do they dedicate that 1 Mbps to you? Thinking they do, each of you dont get that 1 Mbps. its being shared (eually or non equally-depending upon the usage- web, mail, ftp, how many web pages opend at a time, etc services).
## It does matter, bandwidth(bw) will be shared according to the usage, and downloading files' size/types.
### No, the bandwidth is not wasted when any pc stays idle or doesnt request for any files from the web or doesnt send any request to the ISP for anything. the only thing this pc could do is to send a few IP packets to the switch to make sure its getting response from the switch. Only if any of the PC is infected with virus, trojans, ads, spywares, it'll waste your bandwidth

Only very special switches can manage who gets what bandwidth. Most switches just moves data as its being received from the internet, which is usually received packs of one thing then packs of something else as being fed from the ISP.
Imagine your 4 users being fed internet information from a funnel through the roof. Each user shouting up for a response from the server above. The server then feeds the data requested into the funnel. Each of the requests will come almost equally depending on when the server starts feeding and how much data is already in the funnel. If the funnel is empty the data comes through almost instantly, if data is getting filled up in the funnel then you will start seeing delays.

So basically, what happens when all the users are downloading movies, or want to play bandwidth intensive online games at the same time. Does it mean that some users will get higher bandwidth or is it divided equally? Is thier a priority system in the switch or how does it deal with this situation? I don't think it can give 900kb to one user and leave the other 100kb to be shared by the rest , right?
