Sejarah Jaringan Komputer (Network)

Sejarah Network (Jaringan Komputer)

• Pengertian jarinag komputer ( Network)

Jaringan komputer atau network merupakan sekumpulan komputer, printer, dll yang berhubungan satu dengan lainnya dengan menggunakan sistem komunikasi. Informasi dan data terhubung dapat melalui kabel-kabel atau tidak, sehingga user dapat saling bertukar data, dokumen atau informasi. Juga dapat mencetak mencetak pada print dalam waktu yang bersamaan dengan menggunakan software dan hardware yang terhubung dengan jaringan tersebut.
Adapun sekumpulan komputer, printer atau periferal yang terhubung dengan jaringan disebut node. Sebuah jaringan komputer dapat memiliki dua, puluhan, ribuan atau bahkan jutaan node.

• Jenis Jaringan

Secara umum, jenis jaringa dapat dibagi menjadi:
1.Local Area Network (LAN)
2.Metropolitan Area Network (MAN)
3.Wide Area Network (WAN)
4.Internet
5.Jaringan Tanpa Kabel

• Sejarah Jaringan Komputer secara umum:

1. Tahun 1940-an di Amerika Serikat, lahir sebuah konsep jaringa dari sebuah proyek pengembangan komputer model I yang ada di Bell dan group riset Harvard University yang dipimpin profesor H. Aiken. Proyek ini awalnya hanya ingin memanfaatkan perangkat komputer yang diharuskan dipakai bersama, maka dibuatkan proses beruntun dengan sistem antrean.
2. Tahun1950-an ketika janis super komputer muncul, sebuah komputer mesti melayani beberapa terminal. Karena itu ditemukan konsep distribusi proses berdasarkan waktu atau TSS (Time Sharing System), dan untuk pertama kali terbentuklah jaringan komputer (network) pada lapis aplikasi. Pada sistem TSS beberapa terminal terhubung ke sebuah host komputer. Dalam proses TSS pula mulai nampak kerja sama antara teknologi komputer dan teknologi telekomunikasi yang pada awalnya berkembang sendiri-sendiri. gambar Jaringan komputer model TSS
   
3. Tahun 1970-an sudah banyak komputer yang dapat dihubungkan melalui jaringan, sehingga komputer-komputer tersebut dapat berkomunikasi.
4. Tahun 1972 seorang ilmuwan Roy Tomlinson menyempurnakan sebuah program e-mail yang diciptakannya untuk ARPSNET.
5. Tahun 1973 ARPANET sudah berkembang ke luar AS. 2 orang ahli komputer asal AS memberikan gagasan yang menjadi cikal bakal International Network (Internet).
6. Memasuki tahun 1970-an pula , harga perangkat komputer besar mulai terasa sangat mahal, oleh sebab itu mulailah digunakan konsep proses distribusi (Distributed Processing) dalam jaringan. Dalam proses ini beberapa host komputer akan mengerjakan sebuah pekerjaan besar secara paralel untuk melayani terminal- terminal yang tersambung secara seri disetiap host komputer. Dalam proses distribusi ini sudah tentu diperlukan perpaduan atau kerjasama yang mendalam antara teknologi komputer dan telekomunikasi, karena selain proses yang harus didistribusikan, semua host komputer juga wajib melayani terminal-terminalnya dalam satu perintah dari komputer pusat.

7. Tahun 1982 dibentuk Transmission Contron Protocol/Internet Protocol (TCP/IP) yang kita kenal hingga saat ini dikarenakan komputer yang menggunakan atau membentuk jaringan semakin hari semakin banyak..
8. Tahun 1984 muncul 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.
9. Pada tahun 1988 Jarko Oikarinen dari Finland memperkenalkan IRC.
10. Tahun 1992 Tim Berners Lee telah menemukan program editor dan browser yang bisa menjelajah antara satu komputer dengan komputer lain. Program ini disebut www (World Wide Web) yang kenudian membuat perkembangan jaringan komputer (network) menjadi lebih pesat. Dan kemudian memunculkan istilah browsing.

When you child, did you have a wish but became different when you was grow up????

Me, when I was child, six year old exacly, I didn’t know why I really wanna be an agricultural engineer. At the time, I just think about how the field, garden, view, tree, grass look so beautiful, that’s reason why I want to be an agricultural engineer.

But my wish change anymore when I was Junior High school, at the time I wanna be a journalist. If I have an assignment from my teacher to presentation, and need an information for finish my paper, I have a work to interview an important figure. Such as head Policy in Karawang, head of Hospital in Karawang, etc. and that’s make me anthusiastic. I can meet with important figure in my town, I can ask them any question, and be a professional. Hehe..

Ohh ya, I think be a journalist is very happiness, because we can meet with many people, like a celebrities, governor, and Mr. President maybe, we can ask anything question, arrived to many place, around of Indonesia, and maybe around the world. Oh.. thats all just in my mind.

Forget it,, because know, i want to be a manager of Bank, because i study in Informatics management, and also i want to be a good person, and can make my parents happy in their life...

I think enough for post today,,,we will meet in next my post.
