1. The Internet is a worldwide collection ofcomputer networks cooperating with eachother to exchange data using a commonsoftware standard.

2. Before the globally spread internetworking, communication networks had limited communications between the stations on the network.-Advanced Research Projects Agency Network(ARPANET) - a nationwide computer network in the USA. (1969) - ARPANET became the technical core of what would become the internet. -X.25 protocols -Unix-to-unix copy(UUCP) -FidoNet -CYCLADES..and a few more

3. Internet Protocol Suite(TCP/IP), on 1982, was standardized to unify the separated networks. The term "internet" was adopted in the first RFC published on the TCP protocol. In general, an internet was any network using TCP/IP.

4. During the next two decades, the network thatevolved was used primarily by academic institutions,scientists and the government for research andcommunications. The appeal of the Internet to thesebodies was obvious, as it allowed disparate institutions toconnect to each others computing systems and databases. The nature of the Internet changed abruptly in 1992,when the U.S. government began pulling out of networkmanagement, and commercial entities offered Internetaccess to the general public for the first time. This changein focus marked the beginning of the Internetsastonishing expansion.

5. Email is shorthand term meaningElectronic Mail. Email much the same as aletter, only that it is exchanged in a differentway. Computers use the TCP/IP protocol suiteto send email messages in the form of packets.The first thing you need to send and receiveemails is an email address. When you createan account with a Internet Service Provider youare usually given an email address to send fromand receive emails.

6. Email AddressesAn e-mail address typically has two main parts: Ex. editor@internet-guide.co.uk -The first part is your username. You set up the username with your Internet provider or e-mail service. It might be any name of your choice. Dividing the two, is the @ (at) symbol. The second part, is the name of the computer that handles your mail. The computer is also called a server. Your Internet Service Provider (ISP) or e-mail service has a particular name for their server - like aol.com for America Online or yahoo.com for those who go through the Yahoo service.

7. A system of Internet servers that support specially formatted documents. The documentsare formatted in a markup languagecalled HTML (Hyper-Text Markup Language)that supports links to other documents, as wellas graphics, audio, and video files. This meansyou can jump from one document to anothersimply by clicking on hot spots. Not all Internetservers are part of the World Wide Web.

8. The Web is just one of the ways thatinformation can be disseminated over theInternet. The Internet, not the Web, is alsoused for e-mail, which relieson SMTP, Usenet news groups, instantmessaging and FTP. So the Web is just aportion of the Internet, albeit a largeportion, but the two terms are notsynonymous and should not be confused.

9. There are several applications called Web browsers that make it easy to access the World Wide Web.

10. The internet allows the users to easilyconnect to other computers all over theworld anytime and anywhere, which makeseverything easier. With this, work can be done at home orany place having an internet connection.

11. A virtual private network (VPN) is aprivate computer network that interconnectsremote (and often geographically separated)networks through primarily publiccommunication infrastructures such as theInternet. VPNs provide securitythrough tunneling protocols and securityprocedures such as encryption. Meaning, onecan have complete access of all theirfiles/data even if they are away from theoffice.

12. The easy communication anddata/information transferring over theinternet via internet chat has madecollaborative work for groupseasier, cheaper, and sometimes free. It alsoallows the formation of such groups to beeasier.

13. Version control systems allows a teamof developers (which could be distributedgeographically) to be working on the sameset of files at once without interrupting eachothers work.

14. File sharing, is of course, a lot easier because ofthe internet. Any computer file can be e-mailed as anattachment, uploaded to a website for easydownloading ,or be put into a shared location thatcan be easily accessed by colleagues. For large numbers of downloading, a mirror sitecan be used. It is an exact copy of another Internetsite. Mirror sites are most commonly used toprovide multiple sources of the same information,and are of particular value as a way of providingreliable access to large downloads.

15. Peer-to-peer file sharing Users can use software that connects into a peer-to-peer network to search forshared files on the computers of other users(i.e. peers) connected to the network.Typically, large files are broken down intosmaller chunks, which may be obtained frommultiple peers and then reassembled by thedownloader.

16. This function of the internet affects theproduction, sale, and distribution of anyproduct , like softwareproducts, music, videos, films, photography,etc., globally.

17. Streaming or media streaming is atechnique for transferring data so that it can beprocessed as a steady and continuous stream.Streaming technologies are becomingincreasingly important with the growth of theInternet because most users do not have fastenough access to downloadlarge multimedia files quickly. Withstreaming, the client browser or plug-in canstart displaying the data before the entire filehas been transmitted.

18. For streaming to work, the client sidereceiving the data must be able to collect thedata and send it as a steady stream to theapplication that is processing the data andconverting it to sound or pictures. This meansthat if the streaming client receives the datamore quickly than required, it needs to save theexcess data in a buffer. If the data doesnt comequickly enough, however, the presentation ofthe data will not be smooth.

19. YouTube is the leading free streaming site.

20. Live streaming, delivering live over theInternet, involves a camera for the media, anencoder to digitize the content, a mediapublisher, and a content delivery network todistribute and deliver the content.

21. VoIP stands for Voice-over InternetProtocol, a category of hardware andsoftware that enables people to usethe Internet as the transmission medium fortelephone calls by sending voice data inpackets using IP rather than by traditionalcircuit transmissions of the PSTN.

22. One advantage of VoIP is that thetelephone calls over the Internet do notincur a surcharge beyond what the user ispaying for Internet access, much in the sameway that the user doesnt pay for sendingindividual e-mails over the Internet, whichmakes it a competitive alternative totraditional phone services.

23. VoIP is commonly used in instantmessaging, usually in the form of video callsnowadays VoIP has also become a popular form ofgaming communication.
