Hvad er et netværk ?

The Internet, sometimes called simply \"the Net,\" is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was first known as the Advanced Research Projects Agency Network. The original aim was to create a network that would allow users of a research computer at one university to be able to \"talk to\" research computers at other universities. A side benefit of ARPANet\'s design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disaster.

Today, the Internet is a public, cooperative, and self-sustaining facility accessible to hundreds of millions of people worldwide. Physically, the Internet uses a portion of the total resources of the currently existing public telecommunication networks. Technically, what distinguishes the Internet is its use of a set of protocols called TCP/IP (for Transmission Control Protocol/Internet Protocol). Two recent adaptations of Internet technology, the intranet and the extranet, also make use of the TCP/IP protocol.

For many Internet users, electronic mail (e-mail) has practically replaced the Postal Service for short written transactions. Electronic mail is the most widely used application on the Net. You can also carry on live \"conversations\" with other computer users, using Internet Relay Chat (IRC). More recently, Internet telephony hardware and software allows real-time voice conversations.

The most widely used part of the Internet is the World Wide Web (often abbreviated \"WWW\" or called \"the Web\"). Its outstanding feature is hypertext, a method of instant cross-referencing. In most Web sites, certain words or phrases appear in text of a different color than the rest; often this text is also underlined. When you select one of these words or phrases, you will be transferred to the site or page that is relevant to this word or phrase. Sometimes there are buttons, images, or portions of images that are \"clickable.\" If you move the pointer over a spot on a Web site and the pointer changes into a hand, this indicates that you can click and be transferred to another site.

Using the Web, you have access to millions of pages of information. Web browsing (see surf) is done with a Web browser, the most popular of which are Netscape Navigator and Microsoft Internet Explorer. The appearance of a particular Web site may vary slightly depending on the browser you use. Also, later versions of a particular browser are able to render more \"bells and whistles\" such as animation, virtual reality, sound, and music files, than earlier versions.

Nå ja, et til - hvad er Intra-net ?

Du behøver ikke at svare på alle sp. for at points !

Det må også gerne være dansk og lidt mere kortfattede !

network

In information technology, a network is a series of points or node interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks.
The most common topology or general configurations of networks include the bus, star, and token ring topologies. Networks can also be characterized in terms of spatial distance as local area networks (LAN), metropolitan area networks (metropolitan area network), and wide area networks (wide area network).

A given network can also be characterized by the type of data transmission technology in use on it (for example, a TCP/IP or Systems Network Architecture network); by whether it carries voice, data, or both kinds of signals; by who can use the network (public or private); by the usual nature of its connections (dial-up or switched, dedicated or nonswitched, or virtual connections); and by the types of physical links (for example, optical fiber, coaxial cable, and Unshielded Twisted Pair). Large telephone networks and networks using their infrastructure (such as the Internet) have sharing and exchange arrangements with other companies so that larger networks are created.

Intranet:
et privat, internt netværk (internet - med lille \'i\') i en organisation, der ofte er beskyttet mod Internet-trafik ved hjælp af en firewall, der kontrollerer adgang udefra.

Der findes i dag 2 forskellige typer Intranet:
1) et klientbaseret Intranet, hvor alle softwarekomponenter er installeret på den enkelte medarbejders pc.
2) Et web-baseret Intranet, der kun kræver, at en browser er installeret og hvor hele Intranetsoftwaren er installeret på en server. Denne type kan anvendes på begge sider af firewallen. Fordelen ved sidstnævnte er, at hvis man vælger at have Intranettet udenfor firewallen, og indbygger de sikkerhedsforanstaltninger, der skal til, kan virksomhedens medarbejdere få tilgang til informationsdatabasen uafhængigt af tid og sted.

Arr det lige som at spørge hvordan er et meneske sat sammen...
OKi et netværk er noget som hæger sammen eks: kan 2 computere sættes sammen.. og danne et netværk!
over dette netværk kan man så sende filler ogf spille spil sådan et netværk kalles et INTRANET.
internetet er bygget op på IP adresser. alle som er på INTERnetten har sin helt ejen IP.
når du skriver eksperten i din browser er det kun en genvej til en lang ip adresse.EKS:(128.458.123.458.).

forsent igen!!!!!!!!!!!!11

ok, her er resten på dansk:
Internet:
Det globale computernet, der er koblet sammen på kryds og tværs.
De mest kendte er WWW (hvor de fleste websites ligger), Usenet (nyhedsgrupper) og e-mail-delen, der benyttes til elektronisk post.
For at få adgang til nettet, skal man via en pc ringe op til en Internetudbyder, f.eks. Cybercity, Orange, WorldOnline eller TeleDanmark, der tager sig betalt for at give brugeren adgang til nettet.
De informationer man finder på Internettet er hjemmesider (websites, homepages, wedsteder), altså de steder, hvor en person, et firma eller en organisation har samlet en række informationer i form af tekst, fotos, grafik, lyde, animationer m.v.

Internettet blev opfundet af Vincent Celf, mens han var ansat i det amerikanske forsvars center for avanceret teknologi (DARPA), hvor han i 1969 - sammen med Robert Kahn - opfandt den TCP/IP-protokol, der er grundlaget for Internettet. Et netværk, - uden én styrende computer - der skulle kunne \'overleve\' en atomkrig. Resultatet blev ARPANET, der i starten var mest benyttet af universiteter og militæret, men som senere blev opdelt i MILNET (militærets net og ARPANET (civilets net).
Efter at han havde forladt forsvaret, var han i 1988 med til at åbne nettet for andre end forsvaret. Han er i dag Senior Vice President i det amerikanske telefonselskab MCI WorldCom.

Netværk:
et antal computere, der er forbundet med hinanden hvorved det bliver muligt, at dele hardware, f.eks. printere, scannere samt data.
Brugerne kan også kommunikere over nettet med hinanden.
Der skelnes mellem LAN, WAN, intranet, Internet etc.

tak for point :)
