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:

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.
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
Tahun 1970-an sudah banyak komputer yang dapat dihubungkan melalui jaringan, sehingga komputer-komputer tersebut dapat berkomunikasi.
Tahun 1972 seorang ilmuwan Roy Tomlinson menyempurnakan sebuah program e-mail yang diciptakannya untuk ARPSNET.
Tahun 1973 ARPANET sudah berkembang ke luar AS. 2 orang ahli komputer asal AS memberikan gagasan yang menjadi cikal bakal International Network (Internet).
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. Gambar jaringan komputer model Distributer Processing
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..
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.
Pada tahun 1988 Jarko Oikarinen dari Finland memperkenalkan IRC.
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.

Now, today I will try to tell you about my wish and my dream.

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.

Thank you..

Assalamu'alaikum..
     Hi... How are you today????
Umm... today, i will tell you about my hobbies..again.. n_n
Last week, i was told you about my favourite team of football in the world, thats AC MILAN And CHELSEA, and also litle story about Kimi Raikkonen, F1 rider. You know, first time i like to him, when i was in senior high school, in 2005. I saw him in sport magazine. In that news, Kimi Raikkonen was being rising star in Formula 1 with Fernando Alonso, Jensen Button, etc. I am very exciting to read all that news about Kimi.

Kimi Mattias Raikkonen was born in Espoo, litle city in FINLAND, 17th of October 1979 . Now, he was merried with his girlfriend. He is Ferraris rider. And in 2007, he is a champion in Formula 1 race. Before in Ferrari, he was a McLaren-Mercedes for five season. I often watching his race and i love his performance who full of spirit, maybe his performance in this year not better than last year, but i hope next year he will be champion again in Formula 1, like last year.n_n

        Ok... the other of my hobbies are i like listening music. reading a novel.. Oh, right now, i have read novels from Raditya Dika,the novels tell about his real story and his experience, then he writes in his blog and he made books from that. The story is very funny and he discribe that with fun language style.
      You know Sophie Kinsella??? she is a great novelist. I have four her novells. The tittles are : Confession of a Shopaholic, Shopaholic Abroad, Shopaholic was Slipknot, and Shopaholi and the baby. I love her novels, the story give inspiration for me to live my life. If you want to borrow her novel, you can call me.. ^_^
Thank you...

the third posting about my hobbies..

2008-10-21T02:57:00.000-07:00

Assalamu’alaikum..
In my third posting, I will describe about my hobbies.
Do you have hobbies like me???
Ooh… if you like watching football match, watching F1 race, maybe you are same with me. Aren’t you???
Do you remember if in my first posting, I ever told you about my favorite team football?? Yeah,, I love CHELSEA and AC MILAN.. When I am in junior high school, that’s the beginning I like watching football. The first team who I like is Liverpool, I like because I love Michael Owen, he’s cute, small, but active and cheer up in every his match. But, since his move to Newcastle United, I didn’t respect to him anymore. And because my friends who loved football says that AC MILAN is one of the best team football in the world, the first time I interested to that club, and when I was watching that match I like to Andriy Shevchenko. I love that man.. he is striker, he was born in Kiev, Ukraine, 29th of September. And Dynamo Kiev is his first team. He was merried with Kristen Pasek, a girl from USA. And know, they have a son, his name is Jordan. In 2007, he moved again to CHELSEA, and since he moved to that club, his name not famous anymore. I am very sad, he often be second player in every match. You know, in early year of 2008, AC MILAN brought he again until next year. I hope his performance will better than last year. And although he not be a star again, I still like him. And will always like SHEVA n_n
Tomorrow, AC MILAN and As Roma will meet in the Champion League. I will watching they match, and it must watch.
Oww… you know Kimi Raikkonen?? I like his.He’s racer Formula 1. and he is winner in last year. He’s a Finlandian. Se’s very cool and smart, I often watched his race, but in this year his performance not very good. I hope he will be champion again this year, although his opportunities is small to be a winner.
Maybe enough for my post today.
Thankyou.. n_n
