Sejarah Network

1. Pengertian Jaringan Komputer

Jaringan komputer merupakan suatu sistem yang bekerja sama antara sistem perangkat komputer dengan jaringan lainnya untuk mencapai suatu tujuan yang sama seperti Pembagian Sumber Daya (berbagi dalam pemakaian printer,CPU,memory,harddisk),Komunikasi(Chatting,Instan Message,pengiriman surat elektronik),dan Akses Informasi(browsing,dll).

2. Sejarah Jaringan

- Lahirnya konsep jaringan komputer dimulai pada tahun 1940-an yaitu di Harvard University dipimpin oleh H.Aiken yang sedang melakukan sebuah proyek di Laboratorium Bell agar dapat memakai satu buah perangkat komputer yang akan digunakan secara bersamaan,Lalu dikenal lah istilah Batch Processing(Proses Berurutan) dimana suatu prose situ dilakukan dengan antrian.
- Tahun 1950-an ,dimana suatu perangkat komputer itu harus melayani beberapa terminal.Lalu muncul lah TSS(Time SharingSistem) ,pada TSS ini terminal terhubung secara seri ke satu host komputer.Dari sinilah terlihat perpaduan antara Teknologi komputer dan teknologi komunikasi .
- Tahun 1970-an dikenal istilah Distributed Processing(Proses Distribusi) ,dimana suatu host komputer mengerjakan pekerjaan yang besar secara paralel yang melayani beberapa terminal yang host komputer terhubung secara seri.Sistem kerjanya ini terlebih dahulu sistem harus didistribusikan dan seluruh host komputer harus melayani satu perintah dari komputer pusat.
Selanjutnya setelah Distributed Processing sudah cukup berkembang,maka dunia jaringan pun semakin berkembang sehingga muncul istilah-istilah seperti LAN,MAN,dan WAN.

EVOLUSI JARINGAN

Mainframe → LAN → WAN → Internet

3. Sejarah Jaringan Komputer Dunia

- Dimulai sejak tahun 1969, di Departemen Pertahanan Amerika, membentuk Defense Advance Research Projects Agency ( DARPA ) dengan melakukan program riset untuk menghubungkan beberapa komputer menjadi jaringan organic,Riset ini pun dikenal dengan ARPANET.
- Tahun 1971,ARPANET mulai berkembang ,Roy Tomlinson pun membuat program email pada ARPANET ini.
- Tahun 1971, Roy Tomlinson mengembangkan program emailnya pada ARPANET dan pada saat ini juga ikon @(dibaca “et”) mulai dikenal.
- Tahun 1973,jaringan ARPANET meluas hingga ke luar Amerika dan pertama kali yang menggunakan jaringan ARPANET ini di luar Amerika adalah Komputer University College di London,dan pada saat yang bersamaan juga muncul gagasan besar yang merupakan cikal bakal munculnya TCP (Transmission Control Program)yang dipresentasikan pertama kalinya di Universitas Sussex oleh dua ahli komputer yang mencetuskan gagasan ini yaitu Vinton Cherf dan Bob Khan
- Tahun 1978,terciptalah Newsgroup pertama yang dikenal dengan nama USENET yang diciptakan oleh Tom Truscott, Jim Ellis, dan Steve Bellovin.
- Tahun 1979,diluncurkanlah telepon televisi pertama oleh France Telecon dimana orang bisa menelpon dengan menggunakan video link.
- Tahun 1982,terbentuklah protocol resmi yang diakui oleh seluruh jaringan yaitu TCP dan IP . Pada tahun yang sama di Eropa muncul sebuah jaringan komputer baru yaitu Eunet yang menyediakan jasa email dan newsgroup USENET.
- Tahun 1984,DNS diperkenalkan untuk menyeragamkan alamat domain pada jaringan. Tahun 1988, Jarko Oikarinen dari Fintandia menemu¬kan dan sekaligus memperkenalkan IRC (Internet Relay Chat).
- Tahun 1990 Tim Berners Lee menemukan program editor dan browser yang bisa menjelajah dari satu komputer ke komputer lainnya, yang membentuk jaringan. Program inilah yang disebut www, atau World Wide Web.Pada tahun 1992 muncullah istilah Surfing (Menjelajah).
- Tahun 1994, untuk pertama katinya virtual shopping atau e-retail muncul di situs. Dunia langsung berubah. Di tahun yang sama, Yahoo!(Yet Another Hierarchical Officious Oracle), yang merupakan search engine, didirikan oleh dua orang mahasiswa Stanford University bernama Jerry Yang dan David Filo. Tahun 1994 pun sekaligus tahun kelahiran Netscape Navigator 1.0.
Dan hingga sekarang Jaringan komputer pun semakin meluas perkembangannya,karena seiring perkembangan dunia maka perkembangan teknologi pun ikut berkembang.
