KEAMANAN JARINGAN KOMPUTER

Tujuan Keamanan Jaringan Komputer

•Availability / Ketersediaan

•Reliability / Kehandalan

•Confidentiality / Kerahasiaan

•Cara Pengamanan Jaringan Komputer:
–Autentikasi
–Enkripsi


Autentikasi
•Proses pengenalan peralatan, sistem operasi, kegiatan, aplikasi dan identitas user yang terhubung dengan jaringan komputer

•Autentikasi dimulai pada saat user login kejaringan dengan cara memasukkan password


Tahapan Autentikasi

1. Autentikasi untuk mengetahui lokasi dari peralatan pada suatu simpul jaringan (data link layer dannetwork layer)
2. Autentikasi untuk mengenal sistemo perasi yang terhubung kejaringan (transport layer)
3. Autentikasi untuk mengetahuifungsi /proses yang sedang terjadi disuatu simpul jaringan (session danpresentation layer)
4. Autentikasi untuk mengenali user dan aplikasi yang digunakan
(application layer)

Enkripsi
•Teknik pengkodean data yang berguna untuk menjaga data / file baik didalam komputer maupun pada jalur komunikasi dari pemakai yang tidak dikehendaki

•Enkripsi diperlukan untuk menjaga kerahasiaan data

Resiko Jaringan Komputer

Segala bentuk ancaman baik fisik maupun logik yang langsung atau tidak langsung mengganggu kegiatan yang sedang berlangsung dalam jaringan.

Faktor-Faktor Penyebab Resiko
Dalam Jaringan Komputer
􀂾Kelemahan manusia (human error)
􀂾Kelemahan perangkat keras komputer
􀂾Kelemahan sistem operasi jaringan
􀂾Kelemahan sistem jaringan komunikasi


Ancaman Jaringan komputer
•FISIK
-Pencurian perangkat keras komputer atau
perangkat jaringan
-Kerusakan pada komputer dan perangkat
komunikasi jaringan
-Wiretapping
-Bencana alam

•LOGIK
-Kerusakan pada sistem operasi atau aplikasi
-Virus
-Sniffing

Beberapa Bentuk Ancaman Jaringan
•Sniffer
Peralatan yang dapat memonitor proses yang sedang berlangsung

•Spoofing
Penggunaan komputer untuk meniru( dengan cara menimpa identitas atau alamat IP.

•Remote Attack
Segala bentuk serangan terhadap suatu mesin dimana penyerangnya tidak memiliki kendali terhadap mesin tersebut karena dilakukan dari jarak jaruh dluar sistem jaringan atau media transmisi

•Hole
Kondisi dari software atau hardware yang bisa diakses oleh pemakai yang tidak memiliki otoritas atau meningkatnya tingkat pengaksesan tanpa melalui proses otorisasi

Simple Past

FORM

[VERB+ed] or irregular verbs

Examples:

  • You called Debbie.
  • Did you call Debbie?
  • You did not call Debbie.

USE 1 Completed Action in the Past

Use the Simple Past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind.

Examples:

  • I saw a movie yesterday.
  • I didn't see a play yesterday.
  • Last year, I traveled to Japan.
  • Last year, I didn't travel to Korea.
  • Did you have dinner last night?
  • She washed her car.
  • He didn't wash his car.

USE 2 A Series of Completed Actions

We use the Simple Past to list a series of completed actions in the past. These actions happen 1st, 2nd, 3rd, 4th, and so on.

Examples:

  • I finished work, walked to the beach, and found a nice place to swim.
  • He arrived from the airport at 8:00, checked into the hotel at 9:00, and met the others at 10:00.
  • Did you add flour, pour in the milk, and then add the eggs?

USE 3 Duration in Past

The Simple Past can be used with a duration which starts and stops in the past. A duration is a longer action often indicated by expressions such as: for two years, for five minutes, all day, all year, etc.

Examples:

  • I lived in Brazil for two years.
  • Shauna studied Japanese for five years.
  • They sat at the beach all day.
  • They did not stay at the party the entire time.
  • We talked on the phone for thirty minutes.
  • A: How long did you wait for them?
    B: We waited for one hour.

USE 4 Habits in the Past

The Simple Past can also be used to describe a habit which stopped in the past. It can have the same meaning as "used to." To make it clear that we are talking about a habit, we often add expressions such as: always, often, usually, never, when I was a child, when I was younger, etc.

Examples:

  • I studied French when I was a child.
  • He played the violin.
  • He didn't play the piano.
  • Did you play a musical instrument when you were a kid?
  • She worked at the movie theater after school.
  • They never went to school, they always skipped class.

USE 5 Past Facts or Generalizations

The Simple Past can also be used to describe past facts or generalizations which are no longer true. As in USE 4 above, this use of the Simple Past is quite similar to the expression "used to."

Examples:

  • She was shy as a child, but now she is very outgoing.
  • He didn't like tomatoes before.
  • Did you live in Texas when you were a kid?
  • People paid much more to make cell phone calls in the past.

IMPORTANT When-Clauses Happen First

Clauses are groups of words which have meaning but are often not complete sentences. Some clauses begin with the word "when" such as "when I dropped my pen..." or "when class began..." These clauses are called when-clauses, and they are very important. The examples below contain when-clauses.

Examples:

  • When I paid her one dollar, she answered my question.
  • She answered my question when I paid her one dollar.

When-clauses are important because they always happen first when both clauses are in the Simple Past. Both of the examples above mean the same thing: first, I paid her one dollar, and then, she answered my question. It is not important whether "when I paid her one dollar" is at the beginning of the sentence or at the end of the sentence. However, the example below has a different meaning. First, she answered my question, and then, I paid her one dollar.

Example:

  • I paid her one dollar when she answered my question.

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.

Examples:

  • You just called Debbie.
  • Did you just call Debbie?

ACTIVE / PASSIVE

Examples:

  • Tom repaired the car. Active
  • The car was repaired by Tom. Passive

Simple Past (Past Simple)

The simple past expresses an action in the past taking place once, never, several times. It can also be used for actions taking place one after another or in the middle of another action.

Form of Simple Past


Positive Negative Question
no differences I spoke. I did not speak. Did I speak?

For irregular verbs, use the past form. For regular verbs, just add ed.

Exceptions in Spelling when Adding ed

Exceptions in spelling when adding ed Example

after a final e only add d

love – loved
final consonant after a short, stressed vowel
or l as final consonant after a vowel is doubled
admit – admitted
travel – travelled
final y after a consonant becomes i hurry – hurried

Use of Simple Past

  • action in the past taking place once, never or several times

    Example: He visited his parents every weekend.

  • actions in the past taking place one after the other

    Example: He came in, took off his coat and sat down.

  • action in the past taking place in the middle of another action

    Example: When I was having breakfast, the phone suddenly rang.

  • if sentences type II (If I talked, …)

    Example: If I had a lot of money, I would share it with you.

Simple Past Tense

The simple past tense is used to talk about actions that happened at a specific time in the past. You state when it happened using a time adverb.

You form the simple past of a verb by adding -ed onto the end of a regular verb but, irregular verb forms have to be learned.

Simple Past Timeline

Simple past tense timeline

For example:

"Last year I took my exams."

"I got married in 1992."

It can be used to describe events that happened over a period of time in the past but not now.

For example:

"I lived in South Africa for two years."

The simple past tense is also used to talk about habitual or repeated actions that took place in the past.

For example:

"When I was a child we always went to the seaside on bank holidays."

Take a look at the following conjugation chart. Notice from the above dialogue and following chart that the present continuous (progressive) is used to describe what is happening at the moment. It is also used to describe a plan in the near future (this evening, next week, on Saturday, etc.). The present continuous (progressive) is often used with: now, at the moment, today, this morning - afternoon - evening.

IMPORTANT NOTES:

  • The present continuous (progressive) is used only with action verbs. Example: I am working at the moment NOT I am believing you.
  • The present continuous (progressive) is also used to describe an action which is happening around this moment: Example: I'm reading 'Just in Time' this week. I'm not reading the book at this particular moment, but around this time.
Examples Usage
What are you cooking?
Tom is studying for his exams at the moment.
It isn't raining now. We can go outside.
Actions happening at the present moment.
What are you doing this weekend?
I'm meeting Peter tomorrow morning.
We're driving to Albany this weekend.
Planned future events (usually in the near future)
We're currently working on the Smith account.
What classes are you taking this semester?
We're studying Greek history this month.
Actions or events happening around the present moment.
Structure
In the positive form, follow the form S To be Verb -ing. Remember that you need to conjugate the auxiliary verb 'to be'.
I am (I'm)
You are (You're)
He, She, It is (He's, She's, It's)
We, You, They are (We're, You're, They're)
eating lunch at noon.
Conjugate the helping verb 'To Be' Not Verb - ing to form negatives.
I am not (I'm not)

Present Progressive

The present progressive is formed by combining the verb "to be" with the present participle. (The present participle is merely the "-ing" form of a verb.)

I am studying.
I am studying with María.



In English, present progressive can be used to describe what is happening now, or what will happen in the future.

I am studying now.
I am studying with María tonight.



In Spanish, the present progressive is only used to describe an action that is in the process of taking place. It is not used for future actions.

I am studying now.
(use present progressive)

I am studying with María tonight.
(do not use present progressive)



To form the present progressive in Spanish, combine a form of "estar" with the present participle.

Estoy hablando.
I am speaking.

Juan está comiendo.
John is eating.

María está escribiendo una carta.
Mary is writing a letter.



In order to form the present progressive, you must know how to conjugate the verb estar, and how to form the present participle. You already know how to conjugate the verb estar:

estar

estoy
estás
está
estamos
estáis
están



To form the present participle of regular -ar verbs, add -ando to the stem of the verb.

hablar: hablando
(hablar - ar + ando)

trabajar: trabajando
(trabajar - ar + ando)

estudiar: estudiando
(estudiar - ar + ando)



To form the present participle of regular -er and -ir verbs, add -iendo to the stem of the verb.

comer: comiendo
(comer - er + iendo)

hacer: haciendo
(hacer - er + iendo)

vivir: viviendo
(vivir - ir + iendo)

escribir: escribiendo
(escribir - ir + iendo)



To form the present participle of -ir stem changing verbs, change e:i and o:u in the stem, and then add -iendo to the stem of the verb.

servir: sirviendo
pedir: pidiendo
decir: diciendo

dormir: durmiendo
morir: muriendo
poder: pudiendo



Sometimes when forming the present participle it is necessary to change the spelling of a word so that it agrees with the way it is pronounced. We call this an "orthographic" change. Here are some common examples:

caer: cayendo
creer: creyendo
huir: huyendo
ir: yendo
influir: influyendo
oír: oyendo
traer: trayendo
leer: leyendo
seguir: siguiendo



The following examples illustrate the rules for forming the present participle.

hablar: hablando (-ar)
comer: comiendo (-er)
vivir: viviendo (-ir)
decir: diciendo (e:i)
dormir: durmiendo (o:u)
leer: leyendo (orthographic)
seguir: siguiendo (orthographic)



To form the present progressive, simply conjugate the verb estar to agree with the subject of the sentence, and follow it with the present participle.

Juan está comiendo pan.
John is eating bread.

María y Carmen están hablando con nosotros.
Mary and Carmen are speaking with us.



Remember, only use the present progressive for actions that are "in progress." Compare the uses of the present indicative with the uses of the present progressive.

Estudio español. (Present Indicative)

I study Spanish.
I am studying Spanish (these days).
I do study Spanish.

Estoy estudiando español. (Present Progressive)

I am studying (right now, at this moment) Spanish.

It is important to remember that you would never use the present progressive to say something like "We are going to Spain this summer." Use present progressive only for actions that are "in progress."



Let's add two more verb flashcards: one for present progressive and one for practice in forming the present participle:

Verb Flashcards
Complete List

Present Progressive

estar + present participle
I am speaking (right now, at this moment)
Never use present progressive for something that will occur in the future.

Present Participle (-ando, -iendo, yendo)

hablar - hablando (-ar)
comer - comiendo (-er)
vivir - viviendo (-ir)
decir - diciendo (e:i)
dormir - durmiendo (o:u)
leer - leyendo (orthographic)
seguir: siguiendo (orthographic)

The present progressive puts emphasis on the course or duration of an action.

Time line

The present progressive is used for actions going on in the moment of speaking and for actions taking place only for a short period of time. It is also used to express development and actions that are arranged for the near future.

Present progressive is also known as present continuous.

How do we make the Simple Present Tense?

base

There are three important exceptions:

  1. For positive sentences, we do not normally use the auxiliary.
  2. For the 3rd person singular (he, she, it), we add s to the main verb or es to the auxiliary.
  3. For the verb to be, we do not use an auxiliary, even for questions and negatives.

Look at these examples with the main verb like:


subject

+

I, you, we, they

He, she, it



likes

He, she, it

is

?

you, we, they


late?

How do we use the Simple Present Tense?

We use the simple present tense when:

  • the action is general
  • the action happens all the time, or habitually, in the past, present and future
  • the action is not only happening now
  • the statement is always true

John drives a taxi.

past

present

future


It is John's job to drive a taxi. He does it every day. Past, present and future.

Look at these examples:

  • I live in New York.
  • The Moon goes round the Earth.
  • John drives a taxi.
  • He does not drive a bus.
  • We do not work at night.
  • Do you play football?

Note that with the verb to be, we can also use the simple present tense for situations that are not general. We can use the simple present tense to talk about now. Look at these examples of the verb "to be" in the simple present tense - some of them are general, some of them are now:

Am I right?
Tara is not at home.
You are happy.

past

present

future


The situation is now.

I am not fat.
Why are you so beautiful?
Ram is tall.

past

present

future


The situation is general. Past, present and future.

Simple Present (Present Simple) - Introduction

Simple present is also called present simple.

Time line



The simple present expresses an action in the present taking place once, never or several times. It is also used for actions that take place one after another and for actions that are set by a timetable or schedule. The simple present also expresses facts in the present.

OTHER, ANOTHER

OTHER, ANOTHER

These words refer to something different, remaining, or additional.

They are placed before the noun.

Another is used with singular nouns.

Other with singular or plural.

  • There are other jobs you could try.
  • Where's the other packet of cereals?
  • Is there any other bread?
  • Have another cup of tea.

Other and Another

Other, Another and “A Whole Nuther”

So often I hear people use the word “nuther” when they mean “other”. Like in “that’s a whole nuther story.”How did this happen?

First, I don’t think that the word “nuther/nother” is being substituted for the word “other” in this expression. Rather, the word “whole” is being inserted between elements of the word another: a-whole-nother.

It could be jocular usage, or it could be an example of metanalysis:

The reinterpretation of the form of a word resulting in the creation of a new word; esp. the changing of the boundaries between words or morphological units.

Our word apron, for example, used to be napron, but speakers hearing the words “a napron” thought they were hearing “an apron.” The same thing happened with auger, adder and umpire. Working in the other direction, what we call “a newt” used to be “an ewt(e).”

Some speakers may try to “correct” a whole nuther story to the ungrammatical a whole other story with the result that the latter may become a common usage.

As to how it happened–

“A whole nuther/nother story” has caught on because people who hear it like it.

It also fits the patterns of English speech. The OED, for example, offers several uses of nother, most of them obsolete, but the word has a long history in the language.

The Old English word oþer meant “a second of two.” The merger of an (one) with other is documented from 1225.

Another is different from the other:

another refers indefinitely to any further member of a series of indeterminate extent.

the other points to the remaining determinate member of a known series of two or more.

I don’t think “a whole nuther” belongs in the speech or writing of news announcers or journalists who have a responsibility to adhere to standard usage, but its informal use in conversation doesn’t pain my grammar nerve.

Other And Another

Other and Another

Sekarang ini perkembangan dunia Teknologi Informasi (TI) telah berkembang pesat salah satunya dalam hal bahasa pemrograman. Ada beberapa bahasa pemrograman, salah satunya adalah Java yang sudah tidak di ragukan lagi perannya dalam perkembangan TI.


Java adalah bahasa pemrograman yang dapat berjalan di semua platform tanpa harus mengubah kode sedikitpun dengan syarat pada sistem yang digunakan sudah terdapat JRE (Java Runtime Environment). Hal inilah yang menjadi kekuatan Java sebagai bahasa pemrograman multiplatform write once run anywhere. Aplikasi menggunakan Java sangatlah luas dan dibagi menjadi tiga sub bagian yaitu J2EE (Java 2 Enterprise Edition), J2SE (Java 2 Standard Edition), dan J2ME (Java 2 Micro Edition). Dari ketiga sub bagian tersebut yang membedakan adalah cakupan aplikasi yang ingin dibuat. J2EE digunakan untuk aplikasi yang bersifat enterprise dan dalam sekala yang besar seperti sistem terdistribusi, J2SE digunakan untuk aplikasi standard pada desktop sedangkan J2ME lebih dikonsentrasikan untuk aplikasi yang bersifat embedded seperti mobile device. Dari ketiga sub bagian yaitu J2EE, J2SE, dan J2ME masih dibagi lagi menjadi bagian-bagian yang spesifik dan disesuaikan dengan kebutuhan. J2SE adalah framework yang sering digunakan, karena semua platform Java menggunakan J2SE sebagai base development.


JMF API (Java Media Framework Application Programming Interface) adalah extension dari J2SE yang dikonsentrasikan untuk pemrograman pada multimedia streaming (JMF version 2.1.1e). JMF version 2.1.1e sudah mendukung RTP (Realtime Protocol) yang digunakan sebagai protokol aplikasi yang realtime seperti audio/video streaming. Dengan menggunakan API ini akan mempermudah dalam meng-implementasikan realtime protocol pada multimedia streaming.


JMF API merupakan arsitektur yang menggabungkan protokol dan pemrograman interface untuk merekam, menransmisi, dan playback media. Pada JMF version 2.1.1e, Sun's sebagai perusahaan pengembang bahasa pemrograman Java berinisiatif untuk membawa pemrosesan time-base media kedalam bahasa pemrograman Java. Time-base media adalah mengubah data yang diterima dengan berdasarkan waktu, termasuk didalamnya seperti audio dan video klip, MIDI, dan animasi.


Karakteristik time-based media adalah dibutuhkannya waktu untuk mengirimkan dan memproses media. Ketika media data dialirkan harus ditemukan timing yang tepat untuk menerima dan menapilkannya ini yang sering disebut sebagai streaming media. Misal ketika movie dimainkan, data tidak dapat dikirimkan dengan cepat sehingga akan terjadi delay pada waktu playback. Dengan kata lain, jika data tidak dapat dikirimkan dan diproses dengan cepat maka akan menyebabkan kehilangan data atau dropping frame untuk memperbaiki playback. Untuk mengatasi masalah waktu transfer data maka dikembangkan banyak format audio/video seperti Cinepak, MPEG-1, H.263, JPEG, PCM, Mu-Law, G.723.1 dan lain-lain. Dari masing masing format tersebut akan mempengaruhi kualitas video/audio, kebutuhan CPU, dan bandwidth.

Tujuan dari rancangan pembuatan software, “IMPLEMENTASI JAVA MEDIA FRAMEWORK API PADA MULTIMEDIA STREAMING” adalah sebagai berikut :


1. Menganalisa apakah program yang dibuat bisa berjalan dengan baik dan sesuai dengan yang diharapkan..

2.Agar dapat memahami format yang didukung oleh Java Media Framework API .

3.Dapat mengetahui prinsip transmisi dan cara kerja dari software yang dibuat sehingga dapat digunakan dalam aplikasinya.

4.Menghasilkan produk berupa software yang dapat dikembangkan dan digunakan oleh siapa saja.

5.Melakukan perbandingan menggunakan software lain dalam hal ini menggunakan AmCap(MSI Star Cam 370i) agar dapat mengetahui kelemahan dan kelebihan dari masing-masing software.


Mengingat luasnya masalah yang menyangkut tentang pembuatan tugas akhir “IMPLEMENTASI JAVA MEDIA FRAMEWORK API PADA MULTIMEDIA STREAMING”, maka ruang lingkup masalah akan dibatasi sebagai berikut :

1.Menggunakan webcam yang sudah didukung oleh Java.

2.Diimplementasikan dalam satu kelas jaringan.

3.Format Audio video yang digunakan tidak akan dibahas.

4.Frame rate yang digunakan ± 15 fps.

5.Frame Size yang digunakan ± 640x480.

6.Untuk transmisi video akan menggunakan 15 fps dengan kualitas JPEG 0.5 sedangkan untuk audio akan menggunakan format linear.

STUDI KELAYAKAN IMPLEMENTASI LAYANAN MULTIMEDIA MELALUI BROADBAND WIRELESS ACCESS MMDS DI INDONESIA

Layanan multimedia berbasis broadband wireless access (BWA) memiliki cakupan teknologi, frekuensi dan regulasi yang beragam. Keanekaragaman tersebut mengakibatkan struktur industri layanan multimedia tidak memperoleh skala ekonomi yang tinggi jika diimplementasikan di satu negara, sehingga penyelenggara layanan dan pelanggan akan menanggung biaya relatif tinggi. Hal yang sama terjadi di Indonesia, yakni dualisme regulasi di industri layanan multimedia yang diatur oleh Undang-Undang Telekomunikasi No. 36 Tahun 1999 dan Undang-Undang Penyiaran No. 32 Tahun 2002.

Sebelum layanan multimedia berbasis BWA mengadopsi beragam jenis teknologi dan frekuensi band diimplementasikan, maka perlu adanya pengkajian pemilihan teknologi, frekuensi, channeling plan, kelayakan ekonomi dan skenario implementasi sebagaimana yang ditulis dalam penelitian ini. Benchmarking implementasi layanan multimedia BWA di beberapa negara untuk aspek teknologi dan model bisnis diperoleh dari websites dan publikasi umum. Informasi tersebut sebagai bahan olahan untuk melakukan studi kasus di 32 kota besar.

Studi kasus dilaksanakan dengan mengolah data sekunder (populasi, GDP dan semua data yang berkaitan dengan forecasting demand layanan multimedia) yang dikeluarkan oleh Biro Pusat Statistik (BPS) untuk 32 kota besar. Forecasting dilakukan dalam kurun waktu 10 tahun kedepan dengan mengacu nilai pertumbuhan (CA GR) data sebelumnya.

Hasil analisa menunjukkan bahwa hanya 16 kola besar yang layak secara ekonomi mengimplementasikan layanan BWA pada frekuensi band MMDS 2.5 GHZ dengan menggunakan teknologi DVB-T. Untuk pemerataan layanan multimedia di daerah, maka partisipasi pemerintah daerah, investor (pemegang lisensi) dan mitra investor (financial dan technological investors) sangat diperlukan. Partisipasi ketiga belah pihak tersebut dapat diakomodasikan ke dalam bentuk pola kerjasama. Build Operate and Transfer (BOT) merupakan pola kerjasama yang paling cocok untuk model implementasi layanan multimedia di daerah. Hal ini dikarenakan kebutuhan investasi yang relatif sedikit (US$ 3.8 juta).

Berdasarkan analisa keseluruhan, implementasi layanan multimedia berbasis BWA harus diimplementasikan secepat mungkin dengan membuat peraturan yang berkaitan dengan jenis teknologi, alokasi frekuensi dan jumlah penyelenggara layanan di masing-masing wilayah.

IMPLEMENTASI MULTIMEDIA SERVER UNTUK APLIKASI E-EDUCATION DI ITTELKOM

Penulis Yudha Purwanto
Instansi ITTelkom

Abstrak Jaringan data LAN yang dimiliki ITTelkom saat ini masih kurang optimal pemanfaatannya, masih jarang digunakan untuk menunjang kegiatan belajar mengajar di kampus ini. Jaringan data di ITTelkom dapat dibagi dalam dua domain yaitu jaringan packet switch dan circuit switch. Jaringan packet switch diimplementasikan dalam bentuk wired LAN dan Wireless LAN. Sedangkan jaringan circuit switch sudah tergelar lama dalam jaringan telefon local PABX. Selama ini utilitas penggunaan jaringan LAN intranet di lingkungan LAN ITTelkom masih rendah, dengan trafik yang didominasi trafik ke arah upstream internet. Padahal jaringan data yang telah ada di IT Telkom sangat potensial digunakan sebagai sarana untuk meningkatkan kualitas kegiatan belajar mengajar di kampus. Aplikasi e-education dengan tambahan service multimedia yang melewati jaringan data sebagai tool dari knowledge management system menjadi semakin menarik untuk direalisasikan. Multimedia yang integrasikan dalam sebuah website sebagai interface, memiliki unsur tampilan yang interaktif dan mudah di mengerti user untuk memanfaatkan aplikasi multimedia tersebut. Dalam penelitian ini, akan dilakukan desain dan implementasi untuk membuat sebuah tool KMS e-education dengan service multimedia, untuk melakukan aktivitas , download data akademik, video streaming, percakapan VoIP maupun video call di jaringan data ITTelkom. Dengan adanya website e-education di ITTelkom, aktivitas penunjang edukasi, download data, video streaming, percakapan VoIP maupun video call dapat dilakukan dengan mudah.

The articels

The three articles — a, an, the — are a kind of adjective. The is called the definite article because it usually precedes a specific or previously mentioned noun; a and an are called indefinite articles because they are used to refer to something in a less specific manner (an unspecified count noun). These words are also listed among the noun markers or determiners because they are almost invariably followed by a noun (or something else acting as a noun).


The is used with specific nouns. The is required when the noun it refers to represents something that is one of a kind:

The moon circles the earth.

The is required when the noun it refers to represents something in the abstract:

The United States has encouraged the use of the private automobile as opposed to the use of public transit.

The is required when the noun it refers to represents something named earlier in the text. (See below..)

If you would like help with the distinction between count and non-count nouns, please refer to Count and Non-Count Nouns.
We use a before singular count-nouns that begin with consonants (a cow, a barn, a sheep); we use an before singular count-nouns that begin with vowels or vowel-like sounds (an apple, an urban blight, an open door). Words that begin with an h sound often require an a (as in a horse, a history book, a hotel), but if an h-word begins with an actual vowel sound, use an an (as in an hour, an honor). We would say a useful device and a union matter because the u of those words actually sounds like yoo (as opposed, say, to the u of an ugly incident). The same is true of a European and a Euro (because of that consonantal "Yoo" sound). We would say a once-in-a-lifetime experience or a one-time hero because the words once and one begin with a w sound (as if they were spelled wuntz and won).

Merriam-Webster's Dictionary says that we can use an before an h- word that begins with an unstressed syllable. Thus, we might say an hisTORical moment, but we would say a HIStory book. Many writers would call that an affectation and prefer that we say a historical, but apparently, this choice is a matter of personal taste.

For help on using articles with abbreviations and acronyms (a or an FBI agent?), see the section on Abbreviations.

First and subsequent reference: When we first refer to something in written text, we often use an indefinite article to modify it.

A newspaper has an obligation to seek out and tell the truth.

In a subsequent reference to this newspaper, however, we will use the definite article:

There are situations, however, when the newspaper must determine whether the public's safety is jeopardized by knowing the truth.

Another example:
"I'd like a glass of orange juice, please," John said.
"I put the glass of juice on the counter already," Sheila replied.

Exception:
When a modifier appears between the article and the noun, the subsequent article will continue to be indefinite:
"I'd like a big glass of orange juice, please," John said.
"I put a big glass of juice on the counter already," Sheila replied.

Generic reference: We can refer to something in a generic way by cautionusing any of the three articles. We can do the same thing by omitting the article altogether.

* A beagle makes a great hunting dog and family companion.
* An airedale is sometimes a rather skittish animal.
* The golden retriever is a marvelous pet for children.
* Irish setters are not the highly intelligent animals they used to be.

The difference between the generic indefinite pronoun and the normal indefinite pronoun is that the latter refers to any of that class ("I want to buy a beagle, and any old beagle will do.") whereas the former (see beagle sentence) refers to all members of that class.

Proper nouns: We use the definite article with certain kinds of proper nouns:

* Geographical places: the Sound, the Sea of Japan, the Mississippi, the West, the Smokies, the Sahara (but often not when the main part of the proper noun seems to be modified by an earlier attributive noun or adjective: We went swimming at the Ocean Park)
* Pluralized names (geographic, family, teams): the Netherlands, the Bahamas, the Hamptons, the Johnsons, the New England Patriots
* Public institutions/facilities/groups: the Wadsworth Atheneum, the Sheraton, the House, the Presbyterian Church
* Newspapers: the Hartford Courant, the Times
* Nouns followed by a prepositional phrase beginning with "of": the leader of the gang, the president of our club

Abstract nouns: Abstract nouns—the names of things that are not tangible—are sometimes used with articles, sometimes not:

* The storm upset my peace of mind. He was missing just one thing: peace of mind.
* Injustice was widespread within the judicial system itself. He implored the judge to correct the injustice.
* Her body was racked with grief. It was a grief he had never felt before.

Zero articles: Several kinds of nouns never use articles. We do not use articles with the names of languages ("He was learning Chinese." [But when the word Chinese refers to the people, the definite article might come into play: "The Chinese are hoping to get the next Olympics."]), the names of sports ("She plays badminton and basketball."), and academic subjects ("She's taking economics and math. Her major is Religious Studies.")

When they are generic, non-count nouns and sometimes plural count-nouns are used without articles. "We like wine with our dinner. We adore Baroque music. We use roses for many purposes." But if an "of phrase" comes after the noun, we use an article: "We adore the music of the Baroque." Also, when a generic noun is used without an article and then referred to in a subsequent reference, it will have become specific and will require a definite article: "The Data Center installed computers in the Learning Center this summer. The computers, unfortunately, don't work."

Common count nouns are used without articles in certain special situations:
idiomatic expressions
using be and go We'll go by train. (as opposed to "We'll take the train.)
He must be in school.
with seasons In spring, we like to clean the house.
with institutions He's in church/college/jail/class.
with meals Breakfast was delicious.
He's preparing dinner by himself.
with diseases He's dying of pneumonia.
Appendicitis nearly killed him.
She has cancer
(You will sometimes hear "the measles," "the mumps," but these, too, can go without articles.)
with time of day We traveled mostly by night.
We'll be there around midnight.

Principles of Choosing an Article

Choosing articles and determiners: Briefly defined, a determiner is a noun-marker: when you see one, you know that what follows is a noun or noun phrase. There is a list of such words in the table below. When you place your mouse-cursor over a word or pair of related words (such as either/neither), you will see in the right-hand frame an image describing the kinds of words that word can modify.

Zero article (see table below) means either that no article would be appropriate with that kind of noun or that that kind of noun can be used (in that context) without an article.


If you would like to see these images listed on one page, click HERE.

Notice that there is a difference between a "stressed" some or any and an "unstressed" some or any. Consider the words in ALL CAPS as shouted words and you will hear the difference between these two:

* That is SOME car you've got there!
* I don't want to hear ANY excuse!

As opposed to. . .

* We have some cars left in the lot.
* Isn't there any furniture in the living room?

In terms of the words they usually modify, the unstressed some and any do not modify singular count nouns.
