sejarah jaringan

2009-10-05T01:55:00.000-07:00

Agak sulit juga untuk memulai dari mana sejarah jaringan,karena dari berbagai sumber ada banyak perbedaan,namun dari berbagai sumber ada banyak kesamaan.Untuk itu dapat saya simpulkan sejarah jaringan computer.
Sejarah jaringan komputer adalah sejarah yang komplex. Sejarah ini melibatkan banyak orang dari semua penjuru dunia pada lebih dari 35 tahun terakhir. Ini disajikan dengan pandangan bagaimana internet ditemukan dan kemudian dikembangkan. Proses-proses penemuan dan komersialisasi dapat lebih rumit, tetapi hal ini dapat membantu untuk melihat bagaimana dasar dari pengembangan jaringan komputer.

Pada tahun 1940-an komputer adalah suatu alat dengan ukuran besar yang sangat rentan terhadap kesalahan. Pada tahun 1947, ditemukannya transistor semikonduktor membuka banyak kemungkingan untuk membuat komputer dengan ukuran lebih kecil; dan tentunya lebih handal. Pada tahun 1950-an institusi-institusi besar mulai menggunakan komputer-komputer mainframe, dimana dijalankan dengan program-program punched card.
Di tahun 1950-an ketika jenis computer mulai membesar sampai tercipta supercomputer,maka sebuah computer harus melayani beberapa terminal.Untuk itu ditemukan konsep distribusi proses berdasarkan waktu yang dikenal dengan nama TSS(time sharing system),dan untuk pertama kali terbentuklah jaringan (network) computer pada lapis aplikasi.
Pada system TSS beberapa terminal terhubung ke sebuah host computer. Dalam proses TSS mulai nampak perpaduan teknologi computer dan teknologi telekomunikasi yang pada awalnya berkembang sendiri-sendiri.
Tahun 1957 Advanced Research Project Agency(ARPA) dibentuk oleh Departement of Defense(DoD) USA.
Tahun 1967 desain awal dari ARPANET diterbitkan dan tahun 1969 DoD menggelar pengembangan ARPANET dengan mengadakan riset untuk menghubungkan sejumlah computer sehingga membentuk jaringan organic( program ini dikenal dengan nama ARPANET)
Memasuki tahun 1970-an sudah lebih dari 10 komputer berhasil dihubunggkan sehingga computer-komputer tersebut bias berkomunikasi satu sama lain .
Tahun 1972 Roy Tomlinson berhasil menyempurnakan program e-mail yang diciptakannya 1 tahun sebelumnya untuk ARPANET. Program ini begitu mudah dan langsung popular dengan memperkenalkan ikon @ yang berarti “at” atau”pada”.
Tahun 1973 jaringan computer ARPANET berkembang luas keluar Amerika Serikat. Computer university college di London merupakan computer pertama diluar USA yang menjadi anggota jaringan ARPANET. Ditahun yang sama ,2 orang ahli computer ,Vinton cerf dan Bob kahn mempersentasikan sebuah gagasan yang lebih besar yang mnejadi cikal bakal pemikiran Intenational Network(internet). Ide pertama kalinya dipersentasikan di Sussex University.
Tanggal 26 maret 1976,ratu Inggris behasil mengirim e-mail dari Royal and Radar Establishment di Malvern. Setahun kemudian sudah lebih 100 komputer yang tegabung d ARPANET membentuk suatu network.
pada tahun 1979, Tom Truscott, Jim Ellis, dan Steve Bellovin menciptakan Newsgroups pertama yang diberi nama USENET ( User Network ).
Pada tahun 1981, France Telecommenciptakan sebuah gebrakan baru dengan meluncurkan telepon televisi pertama dunia ( orang dapat saling menelepon sambil berinteraksi denagan Video link. kalo sekarang mungkin disebut video call , kl dulu disebut telepon sambil webcam-an .
Seiring dengan bertambahnya komputer yang membentuk jaringan, dibutuhkan sebuah protokol resmi yang dapat diakui dan diterima oleh semua jaringan. untuk itu, pada tahun 1982 dibentuk sebuah komisi Transmission Control Protocol ( TCP ) atau lebih dikenal dengan sebutan Internet Protocol ( IP ) yang kita kenal hingga saat ini. sementara itu, didaratan Eropa muncul sebuah jaringan tandingan yang dikenal dengan Europe Network ( EUNET ) yang meliputi wilayah Belanda, Inggris, Denmark, dan Swedia. Jaringan eunet ini menyediakan jasa e-mail dan newsgroup USENET.untuk menyeragamkan alamat jaringan komputer yang sudah ada, pada tahun 1984 diperkenalkan system dengan nama DOMAIN yang lebih dikenal dengan Domain Name System ( DNS ). dengan system DNS, komputer yang tersambung dengan jaringan melebihi 1.000 komputer.
pada tahun 1987 diperkirakan komputer yang tersambung ke jaringan tersebut melonjak 10 kali lipat menjadi 10.000 komputer lebih.

tahun 1988, Jarkko Oikarinen berkebangsaan Finlandia menemukan sekaligus memperkenalkan Internet Relay Chat atau lebih dikenal dengan IRC yang memungkinkan dua orang atau lebih pengguna komputer dapat berinteraksi secara langsung dengan pengiriman pesan ( Chatting ). akibatnya, setahun kemudian jumlah komputer yang saling berhubungan melonjak 10 kali lipat. tak kurang dari 100.000 komputer membentuk sebuah jaringan.
Tahun 1992 merupakan tahun yang paling bersejarah, ketika Tim Berners Lee merancang sebuah programe editor dan browser yang dapat menjelajahi komputer yang satu dengan yang lainnya dengan membentuk jaringan. programe inilah yang disebut WWW atau World Wide Web.

Tahun 1992, komputer yang saling tersambung membentuk jaringan sudah melampaui lebih dari satu juta komputer. pada tahun yang sama muncul satu istilah yang tyekenal dengan sebutan Surfing ( Menjelajah ) atau browsing.
Ketika computer-komputer yang membentuk jaringan semakin banyak digunakan di industri – industri maupun perkantoran kecil hingga besar,dan ketika beban pekerjaan bertambah banyak dan harga perangkat besar mulai terasa sangat mahal,maka mulailah digunakan konsep proses terdistribusi (distributed processing). Pada proses terdistribusi sudah mutlak diperlukan perpaduan yang mendalam antara teknologi computer dan telekomunikasi ,karena selain proses yang harus didistribusikan ,semua host computer wajib melayani terminal-terminalnya dalam satu perintah dari computer pusat.
Selanjutnya ketika harga computer mulai turun dan konsep proses terdistribusi sudah matang,maka penggunaan computer dan jaringannya sudah mulai beragam ,dari mulai menangani proses bersama-sama maupun komunikasi antarkomputer (peer to peer system) tanpa melalui kendali computer pusat.
Untuk itu mulailah berkembang teknologi jaringan local yang dikenal dengan sebutan LAN. Demikian pula ketika internet mulai diperkenalkan ,maka sebagian besar LAN yang berdiri sendiri mulai berhubungan satu sama lain sehinnga terbentuklah jaringan raksasa WAN.
Tahun 1994, situs-situs Dunia mulai tumbuh dengan subur ( setidaknya, saat itu terdapat 3.000 alamat halaman ) dan bentuk pertama kalinya Virtual Shopping atau e-retail muncul diberbagai situs. Dunia langsung berubah dengan diluncurkannya perusahaan Search Engine Pertama, yaitu Yahoo!. yang dibangun oleh David Filo dan Jerry yang pada bulan April 1994. Netscape Navigator 1.0. diluncurkan dipenghujung tahun 1994.
