So many genisus, so little time. xxxxxxxxxxhhjiiiiiiiiiiiiiiimik n;OVVVJIRVJJktr4l3/qqmlk,byw455ytttttttttt,..m bse. Your question has been answered by other posters in much detail. You will also be able to answer you own question, by trying to connect to the internet without one. The same question could be said about, why do we need laywers, accountants, doctors, power companies etc etc etc...	robbyp (2751)

Because as far as I know you can't connect directly to a DNS server (If the DNS server replaced the ISP) from your home line and the only other way to do it would be to be your own web host which is not a practicle for the majority of home connections (well not yet anyhow).	winmacguy (3367)

Hence it is not like a normal network, it is a network created by the networking of a whole lot of other networks . . . it is essentially the largest WAN in the world . The Internet is made up of many different, connections most important of these are what we refer to has back-bone connections (basically the "spine" of the network) and like the human body if it get's severed in certain places you lose communications with most, all or some of the other networks . These backbone connections are generally fibre optic cables, which provides the highest speed of communication and data capacity at the moment . Most ISP's have access to these backbones either via their own fibre optic cables or multiple high speed connections (ISDN - just an example not saying this is what they use) You cannot connect directly to the Internet on your own because you have to log into a server that is connected to the Internet already or have your own server connected, but to log into a server you need a log in etc, it's not just a matter of hooking up to a cable somewhere across the world and boom you're on the Internet . To get onto the Internet you need to be one of those smaller networks which make up the Internet . . . this is where the ISP's come in . They provide domains on the Internet (basically a piece of real estate on the Internet) through this they provide us their customers with login's to their server which gives us access to the Internet . Essentially the ISP's domain (piece of real estate) is like a gate . If you know the code (the login name and password your ISP gives you) you can open the gate to get on to the Internet . Having these "gates" is expensive which is why Joe Average cannot connect to the Internet without the intervention of an ISP . I hope that makes sense . This is my own understanding of how the Internet and ISP's work . Feel free to argue, disagree or criticize! cheers chiefnz	chiefnz (545)
533552	2007-03-17 03:29:00	Thanx 4 yr answer metla but I still don't see it. No I don't see the analogy with power companies. That's got nothing to do wivit. *sigh* allah shat by the boolobong IT has provided us all with a huge amount of bullskirting material. If you want. thanx 4 all yr responsnes peeps. Tsk Not very satisfying......but Still don't get the point about ISPs. But hey that's Ok neither do you. Hey whoopee rob99 that was a real gee whizz experience wow how holy hot dog fancy getting to the end of the innernet. I was was like really like really blown away man. Hardly you like, you know, got my like brain together and that like wow and that like shoot and stuff. Still don't say much about why we need a a ISP. ok i think it's safe to say that this thread is pointless mark is either winding us up, refuses to accept an answer to his question, or is just plain thick. that power company analogy, everyone can agree, is bloody well near perfect. It could be extended to nearly every modern service we pay for. hey mark, why do you pay for doctors, lawyers, electricity, phone line, internet, evenFOOD? Because it's much easier and cheaper to buy off another group who specialise in the area and have both the tools and expertise to do the job effectively. Sure it IS possible to be your own ISP, food supplier, legal defense etc, but it isn't worth doing - call the experts So mark asked a question, got many very good answers, and continues to mock and ignore the very people he asked for help. good luck with that. OH, and judging by mark's posts/language/spelling/attitude, he isn't 55, he'd be lucky to be 15. hopefully he'll learn the importance of accepting advice and how to get along. then again, with a post count like that i am curious...	motorbyclist (188)
533553	2007-03-17 03:42:00	I'm inclined to agree with you there motorbyclist. I don't think any answer is going to be good enough for mark c.	winmacguy (3367)

533556	2007-03-18 05:54:00	Great thank yu pctek . I have long appreciatted yr contributions here at pressf1 but that don't really tell me very much . So it's, "a little bit trickier", well I wouldn't be here if I wasn't interested in trickiness . Well now that you have read everyones more detailed explanations of the hardware and sharing of main cables etc you see what I mean by trickier . Its not practical or affordable to do it yourself . You could I suppose if you had the money to set up the basics but then you would be an ISP yourself then, one rapidly going broke unless you attract sufficient customers .	pctek (84)
533557	2007-03-18 06:04:00	Perhaps you dont understand the scale of it now. When I messed about with a direct modem connection to my friend, there was no internet. You had bulletin boards. This was some guy with a server at home that allowed people to dial up and up/download files, leave messages etc. One guy was quite rich and had 6 phone lines so he could have a whole 6 people at once on his bulletin board. He was wildly popular. The internet started off as a way for the miltary to communicate via networks. Universities found this was handy and it went from there - more and more groups hooking up to a giant network. Akld Uni for instance has a large network. When I was there they decreased the budget from $18million to $8million. OK, some of it was PCs for staff and students and associated costs but a huge amount was the many things like mail servers, file servers and stuff, firewalls, routers, switches, hubs, ethernet cabling all over the place, fibre cabling, whacking great radio links, laser links and so on. And the small army employed to keep it all working smoothly. And that was just so the Uni could talk to itself. Now add links to communicate between unis, companies, other countries etc. You want to build that in your back shed? Thats why we pay $40 or so to an ISP.	pctek (84)
533558	2007-03-18 07:01:00	You cannot connect to anything without being allocated an IP Address. These cost money to lease. You then need to have a server to host the IP address and facilitate the connection to other servers, that requires multi-party contracts for bandwidth (as many other companies are involved). Bandwidth is usually contracted in blocks, the minimum amount you would need to buy would cripple an individual, hence as Greg has pointed out there have to be economies of scale. Without having an IP address (leased from a block pool managed by IANA) and a server that has contracted (and paid) connections to the "information highway" owned, maintained and managed by others you cannot connect to anything on the internet.	godfather (25)
