As telephone networks are crucial to the Internet, so far...
the ISPs (Internet Service Providers) are often one and the same as the telephone network provider.
It's obvious why and how this happened. It was of course both convenient, handy and probably in some respect even fortunate for the development of the Internet into what it has become today.
However, the fact that the ISPs and the telephone networks in some case are owned and operated pretty much by the same organization and funds might not turn out in favor of the PC user, the surfer. Look at the way Telia in Sweden sits on all the resources one way or the other.
There is talk lately about that there has been some sort of competition established in Sweden but basically it's hard to see where and how. Tradition has it that the Swedish Government, Telia and some major organizations are so closely knitted together that a truly free enterprise within the telephony market is yet to be seen.
Satellites, as a replacement and improvement to some of the existing "earth-bound" telephone networks on the ground, will most certainly become one of the major future steps in the "upgrade" of the whole Internet that sooner or later is bound to happen.
Protocols are rules, or sets of rules, used to stipulate/regulate/specify how the exchange of information should or must be accomplished.

Why? Jo därför att du måste kunna göra i ordning din dator för uppkoppling och användning gentemot Internet då du skaffar en egen ny dator eller installerar nya eller andra program.
När man "konfigurerar" en dator, anpassar den för ett visst användningsområde eller gör nyinstallation etc, så är det vissa funktioner i systemprogrammet som måste aktiveras eller startas och de ovannämnda s.k. protokollen kommer vi inte ifrån.
