Key ingredients: ISPs, telephone networks, routers, private networks, company networks (LANs & WANs), servers and stand-alones, workstations, mainframes, computer websites, intranets, homepages, open & public databases, university networks, multinational networks, corporate networks and still more routers, routers, servers and routers doing the work of arranging and guiding the traffic. 
Not to mention web browsers, modems, ISDN, A/D converters, gateways, bridges and protocols of all sorts.

 

 

The Internet is like a huge network of networks; servers, computers, mainframes, websites, homepages, traditional desktop telephones, cell phones & telephone wires, optic & copper cable networks, cable TV networks, routers, satellites and other means of communication, all intertwined into one gigantic network where anything and anybody might be reached, read, listened to, looked at, copied  or manipulated depending upon various safety measures, technical equipment, user literacy and aims or goals involved. 
 Mail and mailing have never been easier!

 

 

Information resources, good or bad, have never ever before been so easily accessible for such a vast majority of people and interests, no matter of what origin.

Never before have information masses of any substance been so easily gathered or distributed, for better or worse.

Some people say they are afraid of the dark, some might be afraid of the jungle and there's always somebody afraid of Virginia Wolf.

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
Protocols are rules, or sets of rules, used to stipulate/regulate/specify how the exchange of information should or must be accomplished. 
The most widely used protocols on the Internet belong to a group referrred to as TCP/IP, short for Transmission Control Protocol/Internet Protocol.

 

Några av de s.k. protokoll som gör surfande och e-postande möjligt skall du känna till och de är i första hand följande:

FTP, short for File Transfer Protocol, when you want to transfer a file from one computer to another.
To quickly obtain the TCP/IP configuration of a computer, open Command Prompt, and then type ...

SMTP, short for Simple Mail Transfer Protocol,  for sending e-mail
HTTP, short for Hyper Text Transfer Protocol, when an HTML-page is being sent from a web server to a client (from server to a user;  client= a user PC).

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.
