Sejarah Internet

Internet merupakan jaringan komputer yang dibentuk oleh Departemen Pertahanan Amerika Serikat di tahun 1969, melalui proyek ARPA yang disebut ARPANET (Advanced Research Project Agency Network), di mana mereka mendemonstrasikan bagaimana dengan hardware dan software komputer yang berbasis UNIX, kita bisa melakukan komunikasi dalam jarak yang tidak terhingga melalui saluran telepon. Proyek ARPANET merancang bentuk jaringan, kehandalan, seberapa besar informasi dapat dipindahkan, dan akhirnya semua standar yang mereka tentukan menjadi cikal bakal pembangunan protokol baru yang sekarang dikenal sebagai TCP/IP (Transmission Control Protocol/Internet Protocol).

Tujuan awal dibangunnya proyek itu adalah untuk keperluan militer. Pada saat itu Departemen Pertahanan Amerika Serikat (US Department of Defense) membuat sistem jaringan komputer yang tersebar dengan menghubungkan komputer di daerah-daerah vital untuk mengatasi masalah bila terjadi serangan nuklir dan untuk menghindari terjadinya informasi terpusat, yang apabila terjadi perang dapat mudah dihancurkan.
Pada mulanya ARPANET hanya menghubungkan 4 situs saja yaitu Stanford Research Institute, University of California, Santa Barbara, University of Utah, di mana mereka membentuk satu jaringan terpadu di tahun 1969, dan secara umum ARPANET diperkenalkan pada bulan Oktober 1972. Tidak lama kemudian proyek ini berkembang pesat di seluruh daerah, dan semua universitas di negara tersebut ingin bergabung, sehingga membuat ARPANET kesulitan untuk mengaturnya.
Oleh sebab itu ARPANET dipecah manjadi dua, yaitu "MILNET" untuk keperluan militer dan "ARPANET" baru yang lebih kecil untuk keperluan non-militer seperti, universitas-universitas. Gabungan kedua jaringan akhirnya dikenal dengan nama DARPA Internet, yang kemudian disederhanakan menjadi Internet.

[sunting] Daftar kejadian penting

Tahun	Kejadian
1957	Uni Soviet (sekarang Rusia) meluncurkan wahana luar angkasa, Sputnik.
1958	Sebagai buntut dari "kekalahan" Amerika Serikat dalam meluncurkan wahana luar angkasa, dibentuklah sebuah badan di dalam Departemen Pertahanan Amerika Serikat, Advanced Research Projects Agency (ARPA), yang bertujuan agar Amerika Serikat mampu meningkatkan ilmu pengetahuan dan teknologi negara tersebut. Salah satu sasarannya adalah teknologi komputer.
1962	J.C.R. Licklider menulis sebuah tulisan mengenai sebuah visi di mana komputer-komputer dapat saling dihubungkan antara satu dengan lainnya secara global agar setiap komputer tersebut mampu menawarkan akses terhadap program dan juga data. Di tahun ini juga RAND Corporation memulai riset terhadap ide ini (jaringan komputer terdistribusi), yang ditujukan untuk tujuan militer.
Awal 1960-an	Teori mengenai packet-switching dapat diimplementasikan dalam dunia nyata.
Pertengahan 1960-an	ARPA mengembangkan ARPANET untuk mempromosikan "Cooperative Networking of Time-sharing Computers", dengan hanya empat buah host komputer yang dapat dihubungkan hingga tahun 1969, yakni Stanford Research Institute, University of California, Los Angeles, University of California, Santa Barbara, dan University of Utah.
1965	Istilah "Hypertext" dikeluarkan oleh Ted Nelson.
1968	Jaringan Tymnet dibuat.
1971	Anggota jaringan ARPANET bertambah menjadi 23 buah node komputer, yang terdiri atas komputer-komputer untuk riset milik pemerintah Amerika Serikat dan universitas.
1972	Sebuah kelompok kerja yang disebut dengan International Network Working Group (INWG) dibuat untuk meningkatkan teknologi jaringan komputer dan juga membuat standar-standar untuk jaringan komputer, termasuk di antaranya adalah Internet. Pembicara pertama dari organisasi ini adalah Vint Cerf, yang kemudian disebut sebagai "Bapak Internet"
1972-1974	Beberapa layanan basis data komersial seperti Dialog, SDC Orbit, Lexis, The New York Times DataBank, dan lainnya, mendaftarkan dirinya ke ARPANET melalui jaringan dial-up.
1973	ARPANET ke luar Amerika Serikat: pada tahun ini, anggota ARPANET bertambah lagi dengan masuknya beberapa universitas di luar Amerika Serikat yakni University College of London dari Inggris dan Royal Radar Establishment di Norwegia.
1974	Vint Cerf dan Bob Kahn mempublikasikan spesifikasi detail protokol Transmission Control Protocol (TCP) dalam artikel "A Protocol for Packet Network Interconnection".
1974	Bolt, Beranet & Newman (BBN), pontraktor untuk ARPANET, membuka sebuah versi komersial dari ARPANET yang mereka sebut sebagai Telenet, yang merupakan layanan paket data publik pertama.
1977	Sudah ada 111 buah komputer yang telah terhubung ke ARPANET.
1978	Protokol TCP dipecah menjadi dua bagian, yakni Transmission Control Protocol dan Internet Protocol (TCP/IP).
1979	Grup diskusi Usenet pertama dibuat oleh Tom Truscott, Jim Ellis dan Steve Bellovin, alumni dari Duke University dan University of North Carolina Amerika Serikat. Setelah itu, penggunaan Usenet pun meningkat secara drastis. Di tahun ini pula, emoticon diusulkan oleh Kevin McKenzie.
Awal 1980-an	Komputer pribadi (PC) mewabah, dan menjadi bagian dari banyak hidup manusia. Tahun ini tercatat ARPANET telah memiliki anggota hingga 213 host yang terhubung. Layanan BITNET (Because It's Time Network) dimulai, dengan menyediakan layanan e-mail, mailing list, dan juga File Transfer Protocol (FTP). CSNET (Computer Science Network) pun dibangun pada tahun ini oleh para ilmuwan dan pakar pada bidang ilmu komputer dari Purdue University, University of Washington, RAND Corporation, dan BBN, dengan dukungan dari National Science Foundation (NSF). Jaringan ini menyediakan layanan e-mail dan beberapa layanan lainnya kepada para ilmuwan tersebut tanpa harus mengakses ARPANET.
1982	Istilah "Internet" pertama kali digunakan, dan TCP/IP diadopsi sebagai protokol universal untuk jaringan tersebut. Name server mulai dikembangkan, sehingga mengizinkan para pengguna agar dapat terhubung kepada sebuah host tanpa harus mengetahui jalur pasti menuju host tersebut. Tahun ini tercatat ada lebih dari 1000 buah host yang tergabung ke Internet.
1986	Diperkenalkan sistem nama domain, yang sekarang dikenal dengan DNS (Domain Name System) yang berfungsi untuk menyeragamkan sistem pemberian nama alamat di jaringan komputer.

[sunting] Kejadian penting lainnya

Tahun 1972, Ray Tomlinson berhasil menyempurnakan program e-mail yang ia ciptakan setahun yang lalu untuk ARPANET. Program e-mail ini begitu mudah sehingga langsung menjadi populer. Pada tahun yang sama, ikon "@" juga diperkenalkan sebagai lambang penting yang menunjukkan “at” atau “pada”. Tahun 1973, jaringan komputer ARPANET mulai dikembangkan ke luar Amerika Serikat.
Komputer University College di London merupakan komputer pertama yang ada di luar Amerika yang menjadi anggota jaringan Arpanet. Pada tahun yang sama, dua orang ahli komputer yakni Vinton Cerf dan Bob Kahn mempresentasikan sebuah gagasan yang lebih besar, yang menjadi cikal bakal pemikiran internet. Ide ini dipresentasikan untuk pertama kalinya di Universitas Sussex.
Hari bersejarah berikutnya adalah tanggal 26 Maret 1976, ketika Ratu Inggris berhasil mengirimkan e-mail dari Royal Signals and Radar Establishment di Malvern. Setahun kemudian, sudah lebih dari 100 komputer yang bergabung di ARPANET membentuk sebuah jaringan atau network. Pada 1979, Tom Truscott, Jim Ellis dan Steve Bellovin, menciptakan newsgroups pertama yang diberi nama USENET. Tahun 1981 France Telecom menciptakan gebrakan dengan meluncurkan telpon televisi pertama, dimana orang bisa saling menelpon sambil berhubungan dengan video link.
Karena komputer yang membentuk jaringan semakin hari semakin banyak, maka dibutuhkan sebuah protokol resmi yang diakui oleh semua jaringan. Pada tahun 1982 dibentuk Transmission Control Protocol atau TCP dan Internet Protokol atau IP yang kita kenal semua. Sementara itu di Eropa muncul jaringan komputer tandingan yang dikenal dengan Eunet, yang menyediakan jasa jaringan komputer di negara-negara Belanda, Inggris, Denmark dan Swedia. Jaringan Eunet menyediakan jasa e-mail dan newsgroup USENET.
Untuk menyeragamkan alamat di jaringan komputer yang ada, maka pada tahun 1984 diperkenalkan sistem nama domain, yang kini kita kenal dengan DNS atau Domain Name System. Komputer yang tersambung dengan jaringan yang ada sudah melebihi 1000 komputer lebih. Pada 1987 jumlah komputer yang tersambung ke jaringan melonjak 10 kali lipat manjadi 10.000 lebih.
Tahun 1988, Jarko Oikarinen dari Finland menemukan dan sekaligus memperkenalkan IRC atau Internet Relay Chat. Setahun kemudian, jumlah komputer yang saling berhubungan kembali melonjak 10 kali lipat dalam setahun. Tak kurang dari 100.000 komputer kini membentuk sebuah jaringan. Tahun 1990 adalah tahun yang paling bersejarah, ketika Tim Berners Lee menemukan program editor dan browser yang bisa menjelajah antara satu komputer dengan komputer yang lainnya, yang membentuk jaringan itu. Program inilah yang disebut www, atau World Wide Web.
Tahun 1992, komputer yang saling tersambung membentuk jaringan sudah melampaui sejuta komputer, dan di tahun yang sama muncul istilah surfing the internet. Tahun 1994, situs internet telah tumbuh menjadi 3000 alamat halaman, dan untuk pertama kalinya virtual-shopping atau e-retail muncul di internet. Dunia langsung berubah. Di tahun yang sama Yahoo! didirikan, yang juga sekaligus kelahiran Netscape Navigator

Japan

Japan is a land of striking scenic beauty. First time visitors are impressed by its greenness and its mountains, which cover nearly three-quarters of the country. Gentle plains and intermountain basins account for only about 25% of Japanese territory. Here, the flat lands are geologically young and the soil runoff from the surrounding mountains is shallow.

The rugged peaks, snow-fed lakes, turbulent rivers, rocky gorges and waterfalls and dense forests are breathtaking, but they put severe limits on livable land. With seventy-five percent of the nation unsuitable for either habitation or cultivation due to mountains and rocky sea coasts, and with only 16 per cent of the land cultivated, the entire Japanese population actually lives in an area roughly the size of the state of Maine, about 85,470 sq km (33,000 sq mi). This makes Japan the most populated country in the world in terms of population per liveable square mile.

Spain

 Spain is the second largest country in Europe, next to France, which is located in an area known as the Iberian Peninsula. This island is surrounded by the Mediterranean Sea in the south to the east, Atlantic Ocean to the west and the Bay of Biscay to the north. Spain is also bounded by the lands of Portugal, France, Andorra, Morocco and Gibraltar.

Iberians were the first people to settle in Spain who were later colonized by the Greeks and Carthaginians. In the 3rd century BC, the Romans ruled. The word Spain originated from the Roman name "Hispania".

Spain is a country that possesses a magnificent mix of art, culture and architecture. It has a lot of beautiful cities and towns that vary in culture, language, climate and customs. Some of the popular cities include Madrid, Barcelona, Sargossa, Valencia, Granada and Seville.

GTA: San Andreas Easter Eggs

• Idle Screensaver

  Do not move CJ for 2-3 minutes. The display will be removed and the camera will start to follow and zoom into any activity going on (ie. Pursuits, fights, people talking).
  
• 
  

  Change the size of the moon

  Shoot the moon with the sniper rifle and it will grow until it reaches a certain size when he will shrink when you shoot it again.
  
• 
  

  Civilian Lemmings

  Go to the gym in Las Venturas, and through the bomb garage next to it. Stand in that alley and look at the building across the street to your right -- and you'll see people jumping and walking off the roof. It will only happen if you stand in that alley and watch it from there. It's pretty much a Lemmings Easter Egg since Rockstar North made Lemmings (the company was known as DMA then)
  

• Funny License Plates

  If you import a car at the docks, most but not all cars have plates that differ from normal ones. One says "our fergie", or "disco stu", and a really special one says "ea sucks". Try it out.
  

• Jesus Saves

  In Los Santos there is a wall painting with a heart, Mary and an angel on it and it says: Jesus Saves. In GTA 1 and 2 on the buildings where you saved it said the same thing.
  

• Gant bridge easter egg

  Get a jetpack and fly to the top of the gant bridge. At the top is a sign saying: "There are no easter eggs up here. Go away."
  

• CJ Sings

  If you leave the game on and don't do anything CJ will sing songs heard on the radio. The songs you will most likely hear CJ sing is the songs on your favorite radio station.
