Topologi Jaringan

Topologi Jaringan adalah Konfigurasi tentang bagaimana menghubungkan komputer, kabel dan peripheral lainnya sehingga membentuk sebuah jaringan. Ada beberapa Topologi Jaringan di dalam Dunia Teknologi Informatika ini seperti Topologi Bus, Topologi Ring, dan Topologi Star. Berikut Penjelasan dari 3 Topologi Jaringan ini :

1. Topologi Bus

Topologi Bus merupakan topologi yang banyak digunakan pada masa penggunaan kabel coaxial. Dengan menggunakan T-Connector maka komputer atau perangkat jaringan lainnya bisa dengan mudah dihubungan satu sama lainnya. Pada topologi ini komputer server dan workstation dihubungkan secara berantai melalui kabel tunggal. Topologi ini mudah di kembangkan dan sederhana namun bila salah satu workstation mati maka yang lain akan terpengaruh.


Topologi ini mempunyai karakteristik :

  • Merupakan satu kabel yang kedua ujungnya ditutup dimana sepanjang kabel terdapat node-node.
  • Paling prevevalent karena sederhana dalam instalasi.
  • Signal melewati kabel 2 arah dan mungkin terjadi collision.
  • Problem terbesar dari Topologi Bus adalah Jika salah satu segmen kabel putus, maka seluruh jaringan akan berhenti.
  • Topologi Bus adalah jalur transmisi dimana sinyal diterima dan dikirimkan pada setiap alat/device yang tersambung pada satu garis lurus (kabel), signal hanya akan ditangkap oleh alat yang dituju, sedangkan alat lainnya yang bukan tujuan akan mengabaikan signal tersebut/hanya akan di lewati signal.


2. Topologi Ring

Topologi Ring mirip dengan topologi bus, bedanya topologi ring ujungnya saling berhubungan seolah membentuk lingkaran cincin. Pada topologi ini data mengalir searah, artinya seluruh komputer dalam jaringan akan ikut ambil bagian dalam mengelola informasi yang lewat sehingga bila salah satu rusak maka akan berpengaruh terhadap seluruh jaringan. Topologi ini memanfaatkan kurva tertutup, artinya informasi dan data serta traffic di salurkan sedemikian rupa sehingga masing-masing node tersambung. Umumnya fasilitas ini memanfaatkan fiber optic sebagai sarananya dan twisted pair


Topologi ini mempunyai karakteristik :

  • Lingkaran tertutup yang berisi node-node.
  • Sederhana dalam layout.
  • Signal mengalir dalam satu arah sehingga menghindari terjadi collision (2 paket data tercampur), sehingga memungkinkan pergerakan data yang lebih cepat dan collision detection yang lebih sederhana.
  • Problem terbesar dari Topologi Ring adalah Jika salah satu segmen kabel putus, maka seluruh jaringan akan berhenti.
  • Biasanya topologi ring tidak dibuat secara fisik melainkan direalisasikan dengan sebuah consentrator dan terlihat seperti topologi star.

3. Topologi Star

Dalam Topologi Star, setiap komputer/workstation di hubungkan secara langsung melalui media perantara berupa hub/switch. Topologi Star ini banyak digunakan diberbagai tempat, karena kemudahan untuk menambah, mengurangi atau mendeteksi kerusakan jaringan yang ada. Dengan bermodalkan Hub, Kabel UTP dan Crimtool seseorang sudah bisa membuat dengan mudah sebuah system jaringan dengan Topologi Star.


Topologi ini mempunyai karakteristik :

  • Setiap node berkomunikasi langsung dengan centra node, traffic data mengalir dari node ke central node dan kembali lagi.
  • Mudah di kembangkan karena setiap node hanya memiliki kabel yang langsung terhubung ke central node
  • Keunggulan dari Topologi Star adalah Jika salah satu kabel node terputus yang lainnya tidak terganggu.
  • Dapat digunakan kabel lower grade karena hanya menghandel satu traffic node dan biasanya menggunakan kabel UTP.

Kabel Twisted Pair adalah salah satu dari beberapa tipe kabel yang dapat digunakan untuk membangun sebuah Jaringan Komputer, khususnya pada Jaringan LAN. Kabel Twisted Pair merupakan kabel yang terdiri dari kabel yang saling melilit dan warna yang berbeda. Kabel Twisted Pair ini terdiri dari 2 jenis yaitu Shielded Twisted Pair (STP) dan Unshielded Twisted Pair (UTP). Pada kedua jenis Kabel Twisted Pair ini tidak ada perbedaan yang spesifik bedanya kedua kabel ini adalah Shield dan Unshielded. Berikut Penjelasan dari Kabel UTP dan STP :



1. Kabel Unshielded Twister Paid (UTP)

Kabel UTP terdiri dari 8 buah kabel halus yang saling melilit menjadi 4 pasang. Ke empat pasang kabel tersebut adalah :
  • Pasangan kabel warna hijau dengan Putih lease Hijau
  • Pasangan kabel warna Orange dengan Putih lease Orange
  • Pasangan kabel warna Biru dengan Putih lease Biru
  • Pasangan kabel warna coklat dengan Putih lease Coklat
1.1 Kategori Kabel UTP
  • Cat 1 : Digunakan untuk perangkat komunikasi, seperti kabel telephon.
  • Cat 2 : Kecepatan transfer data mencapai 4 Megabits per second.
  • Cat 3 : Biasanya digunakan untuk topologi token ring dengan kecepatan transfer data mencapai 10 Mbps.
  • Cat 4 : Kecepatan transfer data mencapai 16 Mbps
  • Cat 5 : Kecepatan transfer data mencapai 100 Mbps
  • Cat 5e : Kecepatan transfer data mencapai 100 Mbps – 1 Gigabits.
  • Cat 6 : Kecepatan transfer data hingga 2,5 Gigabit Ethernet dalam jarak 100 Meter atau 10 Gigabits dalam jarak 25 Meter.

1.2 Standarisasi Kabel UTP

Pemasangan urutan Kabel UTP umumnya mengikuti aturan standart international yaitu EIA/TIA 568A dan EIA/TIA 568B. Untuk urutan EIA/TIA 568A urutan kabel nya adalah sebagai berikut :

Urutan ke 1 : Putih Hijau

Urutan ke 2 : Hijau

Urutan ke 3 : Putih Orange

Urutan ke 4 : Biru

Urutan ke 5 : Putih Biru

Urutan ke 6 : Orange

Urutan ke 7 : Putih Coklat

Urutan ke 8 : Coklat

Sedangkan urutan EIA/TIA 568B urutan kabelnya adalah sebagai berikut:

Urutan ke 1 : Putih Orange

Urutan ke 2 : Orange

Urutan ke 3 : Putih Hijau

Urutan ke 4 : Biru

Urutan ke 5 : Putih Biru

Urutan ke 6 : Hijau

Urutan ke 7 : Putih Coklat

Urutan ke 8 : Coklat

1.3 Tipe Pemasangan Kabel UTP

Ada 2 jenis tipe pemasangan kabel UTP pada konektor RJ-45 yaitu type straight dan tipe cross.

a. Tipe Straight

Tipe Straight artinya ujung kabel yang satu dengan ujung kabel yang lainnya memiliki urutan kabel yang sama sesuai dengan standart EIA/TIA 568B. Tipe ini digunakan untuk menghubungkan antara PC ke Switch, Router ke Switch, Router ke Hub dan PC ke Hub.


b. Tipe Cross

Pada tipe ini ujung kabel yang satu menggunakan urutan standart EIA/TIA 568A dan ujung yang satu nya lagi menggunakan urutan kabel TIS/EIA 568B dan digunkan untuk menghubungkan PC ke PC, Switch/Hub ke Switch/Hub, dan PC ke Router.


2. Kabel Shielded Twisted Pair (STP)

Kabel Shielded Twisted Pair (STP) sama dengan kabel UTP, tetapi kawatnya lebih besar dan diselubungi dengan lapisan pelindung isolasi untuk mencegah gangguan interferensi. Jenis kabel STP yang paling umum digunakan pada Jaringan LAN

Dari 2 Jenis Kabel Twisted Pair tersebut tidak ada perbedaan lain yang spesifik kecuali Shielded dan Unshielded. Semua Warna Kabel, Kategori Kabel UTP, Standarisasi Kabel, dan Tipe Pemasangan Kabel itu semua sama.

3G (dari bahasa Inggris: third-generation technology) merupakan sebuah standar yang ditetapkan oleh International Telecommunication Union (ITU) yang diadopsi dari IMT-2000[1] untuk diaplikasikan pada jaringan telepon selular. Istilah ini umumnya digunakan mengacu kepada perkembangan teknologi telepon nirkabel versi ke-tiga[2]. Melalui 3G, pengguna telepon selular dapat memiliki akses cepat ke internet dengan bandwidth sampai 384 kilobit setiap detik ketika alat tersebut berada pada kondisi diam atau bergerak secepat pejalan kaki.[2]. Akses yang cepat ini merupakan andalan dari 3G yang tentunya mampu memberikan fasilitas yang beragam pada pengguna seperti menonton video secara langsung dari internet atau berbicara dengan orang lain menggunakan video.[3]. 3G mengalahkan semua pendahulunya, baik GSM maupun GPRS.[4]. Beberapa perusahaan seluler dunia akan menjadikan 3G sebagai standar baru jaringan nirkabel yang beredar di pasaran ataupun negara berkembang[5].

A supervolcanic eruption at Lake Toba around 74,000 years ago could have wiped out as much as 99% of the global human population, reducing the population from a possible 60 million to less than 10 thousand; see Toba catastrophe theory. However, this theory is not widely accepted because the evidence is disputed, and there have been, for instance, no remains found. The eruption is not listed here as it was pre-historic and outside the scope of this article. Also, the Thera eruption in the Aegean Sea between 1550 and 1650 BC may have caused a large number of deaths throughout the region, from Crete to Egypt.
