Sejarah Jaringan Komputer



Awal dari sejarah jaringan komputer adalah sebuah komputer dimanfaatkan untuk aplikasi bersama, mengerjakan beberapa proses script secara berurutan dengan metode antrian tanpa membuang waktu di negara Amerika tahun 1940an.Pada tahun 1950an tercipta super computer,sebuah komputer yang dapat melayani beberapa terminal.

Arti terminal disini adalah tempat orang memasukkan data atau memberikan perintah kepada super komputer tadi. Dari kebutuhan diatas di temukanlan konsep mengenai distribusi proses berdasarkan waktu atau dikenal dengan sebutan TSS (Time Sharing System) yang merupakan bentuk pertama kali jaringan (network) komputer diterapkan.

Pada tahun 1957 Advanced Research Projects Agency (ARPA) dibentuk oleh Departement of Defence (DoD) USA. Pada tahun 1967 desain awal dari ARPANET diterbitkan dan tahun 1969 DoD menggelar pengembangan ARPANET dengan mengadakan riset untuk menghubungkan
sejumlah komputer sehingga membentuk jaringan organik (program ini dikenal dengan nama ARPANET).



Hari bersejarah berikutnya adalah pada tanggal 26 maret 1976,ketika Ratu Inggris berhasil mengirim e-mail dari Royal Signal and Radar Enstablishment di Malvern. Setahun kemdian sudah lebih dari 100 komputer yang tergabung di ARPANET membentuk sebuah network.

Setelah harga komputer mikro sudah terjangkau dan konsep proses distribusi sudah matang, maka penggunaan komputer dan jaringannya sudah mulai beragam dari mulai menangani proses bersama atau komunikasi antar komputer (Peer to Peer System) tanpa melalui komputer pusat.
Kemudian berkembang teknologi jaringan lokal yang dikenal dengan sebutan LAN.
Demikian juga ketika Internet berkembang, maka sebagian besar LAN yang berdiri sendiri mulai terhubung & terbentuk jaringan raksasa WAN.

Pada tahun 1979 Tom Truscott, Jim Ellis, dan Steve Bellovin menciptakan newsgroup pertama yang diberi nama USENET. Tahun 1981 France Telecom menciptakan gebrakan baru dengan meluncurkan telepon TV pertama, dimana orang bisa menelphone sambil melihat lawan
bicaranya melalui video link.


Karena komputer yang membentuk jaringan semakin hari semakin banyak,maka dibutuhkan suatu protokol resmi yang diakui oleh semua jaringan.Pada tahun 1982 dibentuk Transmission Contron Protocol/Internet Protocol (TCP/IP) yang kita kenal hingga saat ini.
Pada tahun 1984 diperkenalkan Domain Name System (DNS) yang merupakan sistem penamaan masing-masing komputer yang terhubung jaringan. Telah terhubung lebih dari 1000 unit komputer hingga tahun 1984 itu dan pada tahun 1987 komputer yang terhubung melebihi angka 10.000 unit.

Tahun 1990 adatah tahun paling bersejarah. Tim Berners Lee menemukan program editor dan browser yang bisa menjelajah dari satu komputer ke komputer lainnya, yang membentuk jaringan. Program initah yang disebut www, atau World Wide Web.
Tahun 1992, komputer yang sating tersambung membentuk jaringan sudah metampaui sejuta komputer, dan di tahun yang sama muncul istilah surfing (menjelajah).
Tahun 1994, situs-situs dunia maya tetah tumbuh menjadi 3000 alamat halaman dan untuk pertama katinya virtual shopping atau e-retail muncut di situs. Dunia langsung berubah. Di tahun yang sama, Yahoo!(Yet Another Hierarchical Officious Oracle), yang merupakan search engine, didirikan oteh dua orang mahasiswa Stanford University bernama Jerry Yang dan David Filo. 

Jaringan komputer didunia saat ini sudah berkembang secara pesat bandwidth yang dahulu kapasitasnya hanya KB, sekarang sudah sampai ke GB.
