Sejarah Network

SEJARAH JARINGAN KOMPUTER
   Jaringan komputer adalah sebuah kumpulan komputer seperti printer dan peralatan lainnya yang terhubung dalam satu kesatuan. Informasi dan data bergerak melalui kabel-kabel atau tanpa kabel sehingga memungkinkan pengguna jaringan komputer dapat saling bertukar dokumen dan data.
Jaringan komputer lahir pada tahun 1940-an di Amerika dari sebuah proyek pengembangan komputer MODEL I di laboratorium Bell dan group riset Harvard University yang dipimpin profesor H. Aiken. Pada mulanya proyek tersebut hanyalah ingin memanfaatkan sebuah perangkat komputer yang harus dipakai bersama. Untuk mengerjakan beberapa proses tanpa banyak membuang waktu kosong dibuatlah proses beruntun (Batch Processing), sehingga beberapa program bisa dijalankan dalam sebuah komputer dengan kaidah antrian.
    Ditahun 1950-an ketika jenis komputer mulai membesar sampai terciptanya super komputer, maka sebuah komputer mesti melayani beberapa terminal. Untuk itu ditemukan konsep distribusi proses berdasarkan waktu yang dikenal dengan nama TSS (Time Sharing System), maka untuk pertama kali bentuk jaringan (network) komputer diaplikasikan. Pada sistem TSS beberapa terminal terhubung secara seri ke sebuah host komputer. Dalam proses TSS mulai nampak perpaduan teknologi komputer dan teknologi telekomunikasi yang pada awalnya berkembang sendiri-sendiri.
    Memasuki tahun 1970-an, setelah beban pekerjaan bertambah banyak dan harga perangkat komputer besar mulai terasa sangat mahal, maka mulailah digunakan konsep proses distribusi (Distributed Processing). dalam proses ini beberapa host komputer mengerjakan sebuah pekerjaan besar secara paralel untuk melayani beberapa terminal yang tersambung secara seri disetiap host komputer. Dalam proses distribusi sudah mutlak diperlukan perpaduan yang mendalam antara teknologi komputer dan telekomunikasi, karena selain proses yang harus didistribusikan, semua host komputer wajib melayani terminal-terminalnya dalam satu perintah dari komputer pusat.
    Selanjutnya ketika harga-harga komputer kecil sudah mulai menurun dan konsep proses distribusi sudah matang, maka penggunaan komputer dan jaringannya sudah mulai beragam dari mulai menangani proses bersama maupun komunikasi antar komputer (Peer to Peer System) saja tanpa melalui komputer pusat. Untuk itu mulailah berkembang teknologi jaringan lokal yang dikenal dengan sebutan LAN. Demikian pula ketika Internet mulai diperkenalkan, maka sebagian besar LAN yang berdiri sendiri mulai berhubungan dan terbentuklah jaringan raksasa WAN.
JENIS JARINGAN KOMPUTER

Secara umum jaringan komputer dibagi atas 5 jenis, yaitu :
1. Local Area Network (LAN)
Local Area Network (LAN), merupakan jaringan milik pribadi di dalam sebuah gedung atau kampus yang berukuran sampai beberapa kilometer. LAN seringkali digunakan untuk menghubungkan komputer-komputer pribadi dan workstation dalam kantor suatu perusahaan atau pabrik-pabrik untuk memakai bersama sumberdaya (misalnya printer) dan saling bertukar informasi.

2. Metropolitan Area Network (MAN)
Metropolitan Area Network (MAN), pada dasarnya merupakan versi LAN yang berukuran lebih besar dan biasanya menggunakan teknologi yang sama dengan LAN. MAN dapat mencakup kantor-kantor perusahaan yang letaknya berdekatan atau juga sebuah kota dan dapat dimanfaatkan untuk keperluan pribadi (swasta) atau umum. MAN mampu menunjang data dan suara, bahkan dapat berhubungan dengan jaringan televisi kabel.

3. Wide Area Network (WAN)
Wide Area Network (WAN), jangkauannya mencakup daerah geografis yang luas, seringkali mencakup sebuah negara bahkan benua. WAN terdiri dari kumpulan mesin-mesin yang bertujuan untuk menjalankan program-program (aplikasi) pemakai.

4. Internet
Sebenarnya terdapat banyak jaringan didunia ini, seringkali menggunakan perangkat keras dan perangkat lunak yang berbeda-beda. Orang yang terhubung ke jaringan sering berharap untuk bisa berkomunikasi dengan orang lain yang terhubung ke jaringan lainnya. Keinginan seperti ini memerlukan hubungan antar jaringan yang seringkali tidak kampatibel dan berbeda. Biasanya untuk melakukan hal ini diperlukan sebuah mesin yang disebut gateway guna melakukan hubungan dan melaksanakan terjemahan yang diperlukan, baik perangkat keras maupun perangkat lunaknya. Kumpulan jaringan yang terinterkoneksi inilah yang disebut dengan internet.

5. Jaringan Tanpa Kabel
Jaringan tanpa kabel merupakan suatu solusi terhadap komunikasi yang tidak bisa dilakukan dengan jaringan yang menggunakan kabel. Misalnya orang yang ingin mendapat informasi atau melakukan komunikasi walaupun sedang berada diatas mobil atau pesawat terbang, maka mutlak jaringan tanpa kabel diperlukan karena koneksi kabel tidaklah mungkin dibuat di dalam mobil atau pesawat. Saat ini jaringan tanpa kabel sudah marak digunakan dengan memanfaatkan jasa satelit dan mampu memberikan kecepatan akses yang lebih cepat dibandingkan dengan jaringan yang menggunakan kabel.
