INTERNET DAN INTRANET


INTERNET DAN INTRANET



Internet adalah rangkaian computer yang terdiri dari dua computer atau lebi yang saling berhubungan kemudian membentuk jaringan computer hingga meliputi jaringan computer di dunia (internasonal) yang saling berinteraksi dan saling berkomunikasi.Menurut segi ilmu pengetahuan internet adalah sebuah perpustakaan besar yang didalamnya terdapat jutaan bahkan milyaran informasi atau data yang beupa teks , grafik , audio , maupun animasi dan lain lain dalam media elektronik.


Sedangkan intranet adalah sebuah jaringan private yang menggunakan protocol protocol internet atau TCP/IP untuk membagi informasi rahasia perusahaan atau operasi dalam perusahaan tersebut kepada para karyawanya .Terkadang istilah intranet hanya merujuk kepaa layanan yang terlihat , yakni situs web internal perusahaan.Untuk membangun sebuah intranet , maka sebuah jaringan haruslah memiliki beberapa komponen yang membangun internet yaitu , protocol internet (protocol TCP/IP , alamat IP , dan komponen lainya) klien dan juga server.

KEUNTUNGAN DAN KERUGIAN PENGGUNAAN INTERNET DAN INTRANET


KEUNTUNGAN DAN KERUGIAN  PENGGUNAAN INTERNET DAN INTRANET
          A.Keuntungan :
1.     Produktifitas kerja meningkat
2.    Efisiensi waktu , karena untuk backup data dapat berlangsung lebih cepat dan mudah
3.    Sebagai alat komunikasi karena dapat menghubungkan ke banyak computer dan  terkoneksi ke jaringan internet
4.    System publikasi web
5.    Efektifitas biaya , dengan adanya penigkatan pada produktifitas kerja efisiensi waktu dapat menekan biaya produksi
6.    Keseragaman informasi
7.    Meningkatakan kerjasama
B.Kelemahan :
1.     Informasi yang salah atau tidak sesuai sehingga mengurangi efektifitasnya
2.    Interaksi di internet yang mungkin tidak brtanggung jawab
3.    Perlu platihan khusus untuk anggota dalam menggunakan intranet
4.    Perlu tenaga ahli untuk membangun dan mengembangkan internet di seuah organisasi  atau perusahaan
5.    Bisa terjadi overload (data penuh) akibat pengiriman pesan antar pengguna yang tidak terkontrol dengan baik.

SEJARAH INTERNET


Sejarah internet dimulai pada 1969 ketika Departemen Pertahanan Amerika, U.S. Defense Advanced Research Projects Agency(DARPA) memutuskan untuk mengadakan riset tentang bagaimana caranya menghubungkan sejumlah komputer sehingga membentuk jaringan organik.Dimana mereke mendemonstrasikan bagaimana dengan hardware dan software computer yang berbasis UNIX kita bisa melakukan komunikasi dalam jarak yang tak terhingga melalui saluran telepon Program riset ini dikenal dengan nama ARPANET.Proyek ini merancang bentuk jaringan , kehandalan, seberapa besar informai dapat dipindahkan , dan akhirnya semua standar yang mereka temukan menjadi cikal bakal pembangunan protocol baru yang sekarang dikenal sebagai TCP/IP (Transmission Control Protocol /Internet Protocol).Tujuan awal dibangun proyek ini adalah untuk keperluan militer.

Pada 1970, sudah lebih dari 10 komputer yang berhasil dihubungkan satu sama lain sehingga mereka bisa saling berkomunikasi dan membentuk sebuah jaringan. Tahun 1972, Roy Tomlinson berhasil menyempurnakan program e-mail yang ia ciptakan setahun yang lalu untuk ARPANET. Program e-mail ini begitu mudah sehingga langsung menjadi populer.

Pada awalnya ARPANET hanya menghubungkan 4 situs saja , yaitu Stanford Research Institute , University of California , Santa Barbara , University of Utah dimana mereka membentuk satu jaringan terpadu pada tahun 1969 dan secara umum ARPANET diperkenalkan pada bulan oktober 1972.Tidak lama kemudian proyek ini berkembang pesat di seluruh daerah dan semua universitas di Negara tersebut ingin bergabung . Sehingga membuat ARPANET kesulitan untuk mengaturnya.Oleh sebab itu ARPANET dipecah menjadi dua , yaitu “MILNET” untuk keprluan militer dan “ARPANET” baru yang kecil untuk keperluan militer seperti universitas .Gabungan kedua jaringan tersebut akhirnya dikenal nama DARPA internet yang kemudia disederhanakan menjadi internet.

Pada tahun yang sama, icon @ juga diperkenalkan sebagai lambang penting yang menunjukan "at" atau "pada". tahun 1973, jaringan komputer ARPANET mulai dikembangkan ke luar Amerika Serikat. Komputer University College di London merupakan komputer pertama yang ada di luar Amerika yang menjadi anggota jaringan Arpanet. Pada tahun yang sama, dua orang ahli komputer yakni Vinton Cerf dan Bob Kahn mempresentasikan sebuah gagasan yang lebih besar, yang menjadi cikal bakal pemikiran internet. Ide ini dipresentasikan untuk pertama kalinya di Universitas Sussex.

Hari bersejarah berikutnya adalah tanggal 26 Maret 1976, ketika Ratu Inggris berhasil mengirimkan e-mail dari Royal Signals and Radar Establishment di Malvern. Setahun kemudian, sudah lebih dari 100 komputer yang bergabung di ARPANET membentuk sebuah jaringan atau network. Pada 1979, Tom Truscott, Jim Ellis dan Steve Bellovin, menciptakan newsgroups pertama yang diberi nama USENET. Tahun 1981 France Telecom menciptakan gebrakan dengan meluncurkan telpon televisi pertama, dimana orang bisa saling menelpon sambil berhubungan dengan video link.

Karena komputer yang membentuk jaringan semakin hari semakin banyak, maka dibutuhkan sebuah protokol resmi yang diakui oleh semua jaringan. Pada tahun 1982 dibentuk Transmission Control Protocol atau TCP dan Internet Protokol atau IP yang kita kenal semua. Sementara itu di Eropa muncul jaringan komputer tandingan yang dikenal dengan Eunet, yang menyediakan jasa jaringan komputer di negara-negara Belanda, Inggris, Denmark dan Swedia. Jaringan Eunet menyediakan jasa e-mail dan newsgroup USENET.

Untuk menyeragamkan alamat di jaringan komputer yang ada, maka pada tahun 1984 diperkenalkan sistem nama domain, yang kini kita kenal dengan DNS atau Domain Name System. Komputer yang tersambung dengan jaringan yang ada sudah melebihi 1000 komputer lebih. Pada 1987 jumlah komputer yang tersambung ke jaringan melonjak 10 kali lipat manjadi 10.000 lebih. Tahun 1988, Jarko Oikarinen dari Finland menemukan dan sekaligus memperkenalkan IRC atau Internet Relay Chat. Setahun kemudian, jumlah komputer yang saling berhubungan kembali melonjak 10 kali lipat dalam setahun. Tak kurang dari 100.000 komputer kini membentuk sebuah jaringan. 

Tahun 1990 adalah tahun yang paling bersejarah, ketika Tim Berners Lee menemukan program editor dan browser yang bias menjelajah antara satu komputer dengan komputer yang lainnya, yang membentuk jaringan itu. Program inilah yang disebut www, atau World Wide Web. Tahun 1992, komputer yang saling tersambung membentuk jaringan sudah melampaui sejuta komputer, dan di tahun yang sama muncul istilah surfing the internet. Tahun 1994, situs internet telah tumbuh menjadi 3000 alamat halaman, dan untuk pertama kalinya virtual-shopping atau e-retail muncul di internet. Dunia langsung berubah. Di tahun yang sama Yahoo! didirikan, yang juga sekaligus kelahiran Netscape Navigator 1.0.

Lirik Lagu Miley Cyrus feat. Billy Ray Cyrus - Butterfly Fly Away (OST Hannah Montana) Lyrics

You tucked me in, turned out the light
Kept me safe and sound at night
Little girls depend on things like that

Brushed my teeth and combed my hair
Had to drive me everywhere
You were always there when I looked back

You had to do it all alone
Make a living, make a home
Must have been as hard as it could be

And when I couldn't sleep at night
Scared things wouldn't turn out right
You would hold my hand and sing to me

Caterpillar in the tree
How you wonder who you'll be
Can't go far but you can always dream

Wish you may and wish you might
Don't you worry, hold on tight
I promise you there will come a day
Butterfly fly away

Butterfly fly away, butterfly fly away
Flap your wings now you can't stay
Take those dreams and make them all come true

Butterfly fly away, butterfly fly away
We've been waiting for this day
All along and knowing just what to do
Butterfly, butterfly, butterfly, butterfly fly away

Butterfly fly away
Butterfly fly away

lirik lagu Miley Cyrus - Stay

Well it's good to hear your voice
I hope your doing fine
And if you ever wonder,
I'm lonely here tonight
Lost here in this moment and time keeps slipping by
And if I could have just one wish
I'd have you by my side

Oooh, oh I miss you
Oooh, oh I need you

And I love you more than I did before
And if today I don't see your face
Nothing's changed, no one can take your place
It gets harder everyday

Say you love me more than you did before
And I'm sorry it's this way
But I'm coming home, I'll be coming home
And if you ask me I will stay, I will stay

Well I try to live without you
The tears fall from my eyes
I'm alone and I feel empty
God I'm torn apart inside

I look up at the stars
Hoping your doing the same
Somehow I feel closer and I can hear you say

Oooh, oh I miss you
Oooh, oh I need you

And I love you more than I did before
And if today I don't see your face
Nothing's changed, no one can take your place
It gets harder everyday

Say you love me more than you did before
And I'm sorry that it's this way
But I'm coming home, I'll be coming home
And if you ask me I will stay, I will stay
Always stay

I never wanna lose you
And if I had to I would choose you
So stay, please always stay
You're the one that I hold onto
'Cause my heart would stop without you

And I love you more than I did before
And if today I don't see your face
Nothing's changed no one can take your place
It gets harder everyday

Say you love me more than you did before
And I'm sorry that it's this way
But I'm coming home, I'll be coming home
And if you ask me I will stay, I will stay
I'll always stay

And I love you more than I did before
And I'm sorry that it's this way
But I'm coming home I'll be coming home
And if you ask I will stay, I will stay
I will stay

Avril Lavigne in Abbey Dawn Fashion Show (New York)











lirik lagu Alicia Key - If Ain't Got You

I couldn't tell you why she felt that way, 

She felt it everyday. 

And I couldn't help her, 

I just watched her make the same mistakes again. 


What's wrong, what's wrong now? 

Too many, too many problems. 

Dont know where she belongs, where she belongs. 

She wants to go home, but nobody's home. 

Thats where she lies, broken inside. 

With no place to go, no place to go, to dry her eyes. 

Broken inside. 


Open your eyes and look outside, 

Find the reason why, 

You've been rejected, and now you can't find what you left behind. 

Be strong, be strong now. 

Too many, too many problems. 

Dont know where she belongs, where she belongs. 

She wants to go home, but nobody's home. 

Thats where she lies, broken inside. 

With no place to go, no place to go, to dry her eyes. 

Broken inside. 


Her feelings she hides. 

Her dreams she can't find. 

She's losing her mind. 

She's falling behind. 

She can't find her place. 

She's losing her faith. 

She's falling from grace. 

She's all over the place. 


yeah ... 


She wants to go home, but nobody's home. 

Thats where she lies, broken inside. 

With no place to go, no place to go to, dry her eyes. 

Broken inside. 


She's lost inside, lost inside... oh oh. 

She's lost inside, lost inside... oh oh.

lirik lagu Taylor Swift - We Are Never Ever Getting Back Together


I remember when we broke up the first time
Saying, "This is it, I've had enough," 'cause like
We hadn't seen each other in a month
When you said you needed space. (What?)
Then you come around again and say
"Baby, I miss you and I Swear I'm gonna change, trust me."
Remember how That lasted for a day?
I say, "I hate you," we break up, you call me, "I love you."

Oooh we called it off again last night
But oooh, this time I'm telling you, I'm telling you

We are never ever ever getting back together
We are never ever ever getting back together
You go talk to your friends, talk to my friends, talk to me
But we are never ever ever ever getting back together

Like, ever ...

I'm really gonna miss you picking fights
And me, falling for it screaming that I'm right
And you, would hide away and find your peace of mind
With some indie record that's much cooler than mine

Oooh, you called me up again tonight
But oooh, this time I'm telling you, I'm telling you

We are never ever ever getting back together
We are never ever ever getting back together
You go talk to your friends, talk to my friends, talk to me (talk to me)
But we are never ever ever ever getting back together

Oooh oooh oooh oooh

I used to think That we were forever ever
And I used to say never say never
Huh, so he calls me up and he's like, "I still love you"
And I'm like, "I just, I mean this is exhausting, you know, like,
We are never getting back together. Like, ever "

No!

We are never ever ever getting back together
We are never ever ever getting back together
You go talk to your friends, talk to my friends, talk to me
But we are never ever ever ever getting back together

We are not getting back together,
We oh, not getting back together

You go talk to your friends, talk to my friends, talk to me (talk to me)
But we are never ever ever ever getting back together

lirik lagu Fun. feat Janelle Monae - we are young


Give me a second I,
I need to get my story straight
My friends are in the bathroom getting higher than the Empire State
My lover she’s waiting for me just across the bar
My seat’s been taken by some sunglasses asking bout a scar, and
I know I gave it to you months ago
I know you’re trying to forget
But between the drinks and subtle things
The holes in my apologies, you know
I’m trying hard to take it back
So if by the time the bar closes
And you feel like falling down
I’ll carry you home

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

Now I know that I’m not
All that you got
I guess that I, I just thought
Maybe we could find new ways to fall apart
But our friends are back
So let’s raise a cup
‘Cause I found someone to carry me home

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

Carry me home tonight (Nananananana)
Just carry me home tonight (Nananananana)
Carry me home tonight (Nananananana)
Just carry me home tonight (Nananananana)

The moon is on my side
I have no reason to run
So will someone come and carry me home tonight
The angels never arrived
But I can hear the choir
So will someone come and carry me home

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

Tonight
We are young
So let’s set the world on fire
We can burn brighter than the sun

So if by the time the bar closes
And you feel like falling down
I’ll carry you home tonight

Nobody's Home - Avril Lavigne Lyric

Well, I couldn't tell you
Why she felt that way
She felt it every day

And I couldn't help her
I just watched her make
The same mistakes again

What's wrong, what's wrong now?
Too many, too many problems
Don't know where she belongs
Where she belongs

She wants to go home
But nobody's home
That's where she lies
Broken inside

With no place to go
No place to go
To dry her eyes
Broken inside

Open your eyes
And look outside
Find the reasons why

You've been rejected
And now you can't find
What you've left behind

Be strong, be strong now
Too many, too many problems
Don't know where she belongs
Where she belongs

She wants to go home
But nobody's home
That's where she lies
Broken inside

With no place to go
No place to go
To dry her eyes
Broken inside

Her feelings she hides
Her dreams she can't find
She's losing her mind
She's falling behind

She can't find her place
She's losing her faith
She's falling from grace
She's all over the place, yeah

She wants to go home
But nobody's home
That's where she lies
Broken inside

With no place to go
No place to go
To dry her eyes
Broken inside

She's lost inside, lost inside
Oh oh
She's lost inside, lost inside
Oh oh, oh

Tokio Hotel - Moonson

I'm staring at a broken door
There's nothing left here anymore
My room is cold, it's making me insane

I've been waitin' here so long
Another moment seems to have come
I see the dark clouds comin' up again

Running through the monsoon
Beyond the world 'til the end of time
Where the rain won't hurt
Fighting the storm into the blue

And when I lose myself I think of you
Together we'll be running somewhere new
Through the monsoon just me and you

A half moon fading from my sight
I see your vision in it's light
But now it's gone and left me so alone

I'll know I have to find you now
Can hear you name and don't know how
Why can't we make this darkness feel like home?

Running through the monsoon
Beyond the world 'til the end of time
Where the rain won't hurt
Fighting the storm into the blue

And when I lose myself I think of you
Together we'll be running somewhere new
And nothing can hold me back from you
Through the monsoon, hey, hey

I'm fighting all this power coming in my way
Let it take me straight to you
I've been running night and day

I'll be with you soon just me and you
We'll be there soon, so soon

Running through the monsoon
Beyond the world 'til the end of time
Where the rain won't hurt
Fighting the storm into the blue

And when I lose myself I think of you
Together we'll be running somewhere new
And nothing can hold me back from you
Through the monsoon

Through the monsoon
Just me and you
Through the monsoon
Just me and you
