I mean how is the KPS actually created and where does it come from.I know each area has a server and the data come to and each server,but how does the server create the actual kps speed.And it is possible to create your own internet network... theoretically i mean,have your own server that creates data speed?
How is internet data created?

Ok, im going to try and decode the launguage.
first off, kps im assuming you mean kbs? as in kb/s or KB/s? its not "created, its a measurement of throughput or in this case I think your referring to download speed. The internet is made up of a web of servers, routers and infrastructure. You can indeed have your own "network". And yes, if you want speed that badly, you can have that too.
In order to get the speed you need to pull out data from BT's central hub, its like this massive linksys router which sits ontop of the BT tower, you must go there and tap into the mainframe, its behind the big BT sign, thats where "The internet" lives.

i thought it was in a little black box like in the IT crowd
Ok,so bt own a big server i guess,and there are mini local servers that connect to the big server?But i mean is the internet basically a bunch of ethernet cables connected to each other and the speed is determined by the cpu's of the server or what?Also how is data transmitted overseas,through satellites?
lol, I was only messing, they probably own a server or two for sure but in all fairness the intenet is created by loads and loads of servers/routers and infrastructure providing "multiple paths" giving global access its not just one server or route. If it was there would be a lot of smoke coming out the top of it
The speed is determined by your broadband speed over your phone line, how good your connection is, how good/how close the server is to you.
E.G. if you live in reading and your downloading a file from a server in London, assuming you are on ADSL max, you should (in theory) get good speeds if the server is on a good connection (with good upload) assuming its not getting hammered by other downloaders.
If you live in reading and your downloading a file from the US you will notce a decrease in speed.
Believe it or not there are fibre pipes under the atlantic providing the interlink between europe and america.

Pipes all the way over to america?!? I did give that a thought but thought nah cant be,but when did they put them in?But what i am trying to get to is i know it depend on your phoen line or cable,but how is it determined the server side,is it based on how fast the cpus are?the data throughput created by cpus to process what data (websites ect) that are requested by the user?So its like processing soemthing two times,once on your own side,and then on the server side to pull up the data you request?
Sorry if im being really stupid about this but bit confused by it.

Might be best to read this tbh

There have been transatlantic communication cables since the 1850's.

It's just a network, speed is determined by how quickly the computer can serve up data and more practically the speed of the slowest connection between it and you. So the server is probably going to have a gigabit ethernet to the datacenter router, that'll have a gigabit ethernet to the upstream provider and they'll have high bandwidth ATM connections likely. Then it's down again to your ISP, likely via gigabit ethernet to the DSL aggregation router and then over the ADSL network and it's associated bits.
People make it complex but it's just a lot of networks connected together to make a bigger, a big, very well designed one yes, but the technology isn't far removed from what small business use for their networks.
The transatlantic link cables have existed in various forms for a long time, the latest tend to be multiple fibre bundles carrying wavelength traffic for maximum bandwidth (current cables are good for about 3.2Tbps (yes, terabits, 3200 gigabit connections - or in real life 320 STM-64 10Gbit links). There are multiple systems, they're generally commercial and owned by the big backbone carriers (companies who basically own the internet backbone having built it yet nobody has ever heard off - level3, sprint, global crossing etc...)

In the first place, that depends on which kind of data you're talking about. If you're just downloading a static file, like an installer or a movie, then the server is just reading it off a hard drive, so unless the server's really overloaded the speed will be limited by the slowest part of the connection between you and the server (probably your phone line). The server's CPU power doesn't feature so much there, because reading from a disk doesn't use the CPU much.
On the other hand, if you're retrieving a dynamic page - for example, on a forum or a social networking site - then the HTML which is sent to your computer doesn't actually exist anywhere until you request the page*. When the server receives your request, it runs a script (for example, part of a piece of forum software) which retrieves the content (in this case, posts, your user info, etc.) from a database and creates a string of HTML. Your typical web page isn't that big in terms of KB, but fetching information from a database and building a page needs CPU power. So in that case, the server hardware is likely to be a bigger limitation than the connection.
* Unless it's cached, but that's another matter!
Can't remember where i found this but this is a pretty cool image of the undersea cabling:

That was on Digg a while ago, is a great diagram

It's very impressive indeed, I recently paid a visit to one of the big carriers for a poke around one of their sites (arranged by one of our routing vendors who were keen to sell me the same kit they were using).
When I say poke around I mean of course we were escorted everywhere and strictly prohibited from touching anything or even breathing on it too much...
I'm used to dealing with fairly high end setups myself but they're in another world, they're actually using 32x10GigE LAGs for some of their links - 320Gbps I've never seen anything faster than 160Gbps implemented before (that was at LINX) and it makes our 40Gbit links look fairly pathetic. It's slightly mad to wonder how they use it all up...
Unfortunately I signed sufficient NDAs that I can't tell you who the provider was, or who the vendor was, or actually anything...
