Disk Operating System (disingkat DOS) adalah keluarga sistem operasi yang digunakan di komputer pribadi. Sekarang, istilah DOS menjadi istilah generik bagi setiap sistem operasi yang dimuat dari perangkat penyimpanan berupa disk saat sistem komputer dinyalakan.
Keluarga DOS terbagi menjadi bebrapa kelas, yakni
  • MS-DOS (Microsoft Disk Operating System), termasuk di antaranya adalah Tandy DOS, Compaq DOS, Q-DOS (Quick and Dirty Operating System) dan beberapa klon dari sistem operasi MS-DOS yang dijual kepada para pembuat sistem komputer IBM PC/Compatible.
  • IBM PC-DOS (International Business Machine Personal Computer Disk Operating System), yang meskipun masih buatan Microsoft, diubah sedikit-sedikit untuk dapat digunakan oleh komputer IBM PC.
  • DR-DOS (Digital Research Disk Operating System), yang dibuat oleh pembuat sistem operasi CP/M, Gary Kildall.
  • Novell Personal Netware, merupakan versi DR-DOS yang dijual kepada Novell karena perusahaan yang menaungi CP/M mengalami kebangkrutan (Novell mengakuisisi Digital Research Incorporated).
  • Caldera DOS, merupakan versi Novell Personal Netware yang dijual kepada Caldera Corporation.
  • FreeDOS, merupakan versi DOS yang dibangun dari sisa-sisa pengembangan Caldera DOS, yang dikembangkan oleh komunitas open source.
Sistem operasi ini merupakan sistem operasi yang menggunakan antarmuka dengan pengguna berbasis teks (text-mode user interface), dengan tanda kesiapan menerima perintah dari pengguna yang disebut dengan prompt. Prompt default yang digunakan dalam DOS adalah nama path ditambah dengan tanda lebih besar (>), seperti C:\>, C:\DOS\ dan lain-lain. Pengguna juga dapat menggunakan simbol prompt lainnya dengan menggunakan perintah PROMPT.
Sistem operasi ini juga bersifat single-tasking (hanya dapat menjalankan satu program pada satu waktu saja), menjalankan prosesor pada modus real (real mode), dan hanya dapat mendukung satu pengguna dalam satu waktu (single user).

TRUE FRIENDSHIP!

With you, it's all about voiceless communication-
always knowing exactly what to say,
but never actually having to say it.

When no one seems to be listening,
you hear.
When I hurt but don't show it,
you know.
When I turn away to hide my tears,
you see.
When I feel like I can't get through to anyone,
you understand.

Your eyes glow just for me,
and I know you're proud.
You flash your magical, healing smile my way,
and I know everything will be all right.

You know everything there is to know about me.
You know what worries me,
what keeps me up at night,
and what shames me so badly
that I can't share it with anyone.
Most importantly, though,
none of those things bother you.

You've restored my faith in people
and proved that there is a thing
called true friendship.

~Dawn Nissen~


FOREVER FRIEND

Sometimes in life
you find a special friend
Someone who changes your life
just by being part of it.

Someone who makes you laugh
until you can't stop
Someone who makes you believe
that there really is good in the world.
Someone who convinces you
that there really is an unlocked door
just waiting for you to open it.
This is Forever Friendship.

When you're down,
and the world seems dark and empty,
Your forever friend lifts you up in spirit
and makes that dark and empty world
suddenly seem bright and full.

Your forever friend gets you through
the hard times, the sad times,
and the confused times.
If you turn and walk away,
your forever friend follows.
If you lose your way,
your forever friend guides you
and cheers you on.

Your forever friend holds your hand
and tells you that
everything is going to be okay.
And if you find such a friend,
you feel happy and complete,
because you need not worry.
You have a forever friend for life,
and forever has no end.

Thinking Of YOU!

When I open my eyes
to see the sun rise
I think of you.

When I hear a robin sing
on the first day of spring
I think of you.

When I see a red rose
on the bush where it grows
I think of you.

When I feel the summer heat
on the sand beneath my feet
I think of you.

When I sit on a beach
another world just out of reach
I think of you.
When I see the colored leaves
fall to the ground from a light breeze
I think of you.
When I look to the night sky
and see the sparkle like in your eyes
I think of you.

When the snow is coming down
to softly blanket the ground
I think of you.

When I go to bed at night
as I turn out the light
I think of you.
When I'm old and near death
and I draw my last breath
I'll think of you.

I Miss You

Though you are not here
wherever I go or whatever I do
I see your face in my mind
and I miss you so
I miss telling you everything
I miss showing you things
I miss our eyes
secretly giving each other confidence
I miss your touch
I miss our excitement together
I miss everything we share
I don't like missing you
It is a very cold
and lonely feeling
I wish that I could be
with you right now
where the warmth of our love
would melt the winter snows
But since I can't be
with you right now
I will have to be content
just dreaming about
when we'll be together again

-Poem by Susan Polis Schutz


I will be Here!

If in the morning when you wake,
If the sun does not appear,
I will be here.
If in the dark we lose sight of love,
Hold my hand and have no fear,
I will be here.

I will be here,
When you feel like being quiet.
Through the winning, losing, and trying,
we'll be together, And I will be here.

If in the morning when you wake,
If the future is unclear,
I will be here.
I will be true to the promises I've made,
To you and to the one who gave you to me.
I will be here.

~Steven Curtis Chapman~



Dreaming of You!

I lay in bed on a dark,
stormy night
I drift off to sleep, my mind
takes flight
I dream of places far
and near
I wish you could be here.
I hear your voice and
see your smile
I wish it would last
little while
I sometimes wonder if
you ever knew...
That I lay in my bed,
dreaming of you.

~ Melissa Doyle


Our Love

Love is a word, not from the mind
If you look into my eyes,
My Love you will find.
As I look in your eyes
I see us together
And I know this is forever.
As I hold you near
I feel the Love
Without a single fear.
Take my hand and I'll show you the way
Our Love will grow stronger
y day.

Always and Forever

I never get to tell you what I really need to say
How I long to hold you each and every day
You mean more to me than words can ever express
Without you my life would be a total mess
As I look into your eyes, and at your perfect face
I know there will never be anyone to take your place
No matter what problems we may go through
That place in my heart will always be for you
If I am having a hard time letting you in
It's because I have played the game, and never win
Your love means so much to me
I just don't know how to make you see
I don't care what people say
We can stick together anyway
When they come to me, all I see is your face
When they start to speak your voice takes their place
It's a voice that promises to always be there
No matter what they say, I know you still care
Always and Forever is what this means to me
I LOVE YOU, now can you see?

Fortran 5
Website www.komputer.org.uk (offline)
Komputer is a London-based electronic band, composed of Simon Leonard and David Baker.[1]

[edit] Background

Leonard and Baker were originally signed to Mute Records in 1984 under the name I Start Counting [2] and continued with releases under the moniker Fortran 5[3] until the release of Komputer’s debut album, The World of Tomorrow in (1998).
Komputer’s sound is highly electronic, its first album is very influenced by Kraftwerk. The band takes samples from a variety of sources: from Russian cosmonauts to rubbish compactors and mobile phone ringtones.
For Synthetik, the band’s third album, the music gradually evolved over a long period of time, tracks were tried out in live sets then discarded or reworked in the studio, maturing into a return to the more traditional electro sound of the first album, The World Of Tomorrow, with the incorporation of a more experimental and contemporary electronica approach.

puisi

503… (Lima Nol Tiga)
Aku menelponmu dan kau tak menjawabnya
403… (Empat Nol Tiga)
Kudatangi rumahmu dan tak seorangpun berkata engkau ada
405… (Empat Nol Lima)
Kutanya namun tak seorangpun orang rumahmu menjawabnya
500… (Lima Ratus)
Adakah engkau ingin kita berdua putus ?
206… (Dua Nol Enam)
Sebab dulu kau hanya mencintaiku di sebagian
hatimu
302… (Tiga Nol Dua)
Saat denganku engkau mencintaiku, saat dengannya aku engkau lupakan
301… (Tiga Nol Satu)
Dan kini rayuannya membuatmu benar-benar melupakanku
404… (Empat Nol Empat)
Hingga tak ada lagi tempat
Di hatimu untukku

RAM

Dari Wikipedia bahasa Indonesia, ensiklopedia bebas
Langsung ke: navigasi, cari
Memori akses acak (bahasa Inggris: Random access memory, RAM) adalah sebuah tipe penyimpanan komputer yang isinya dapat diakses dalam waktu yang tetap tidak memperdulikan letak data tersebut dalam memori. Ini berlawanan dengan alat memori urut, seperti tape magnetik, disk dan drum, di mana gerakan mekanikal dari media penyimpanan memaksa komputer untuk mengakses data secara berurutan.
Pertama kali dikenal pada tahun 60'an. Hanya saja saat itu memori semikonduktor belumlah populer karena harganya yang sangat mahal. Saat itu lebih lazim untuk menggunakan memori utama magnetic.
Perusahaan semikonduktor seperti Intel memulai debutnya dengan memproduksi RAM , lebih tepatnya jenis DRAM.
Biasanya RAM dapat ditulis dan dibaca, berlawanan dengan memori-baca-saja (read-only-memory, ROM), RAM biasanya digunakan untuk penyimpanan primer (memori utama) dalam komputer untuk digunakan dan mengubah informasi secara aktif, meskipun beberapa alat menggunakan beberapa jenis RAM untuk menyediakan penyimpanan sekunder jangka-panjang.
Tetapi ada juga yang berpendapat bahwa ROM merupakan jenis lain dari RAM, karena sifatnya yang sebenarnya juga Random Access seperti halnya SRAM ataupun DRAM. Hanya saja memang proses penulisan pada ROM membutuhkan proses khusus yang tidak semudah dan fleksibel seperti halnya pada SRAM atau DRAM. Selain itu beberapa bagian dari space addres RAM ( memori utama ) dari sebuah sistem yang dipetakan kedalam satu atau dua chip ROM.
