Pengertian Topologi Jaringan

Pengertian Topologi Jaringan

 Topologi jaringan adalah bagian yang menjelaskan hubungan antar komputer yang di bangun berdasarkan kegunaan, keterbatasan resource dan keterbatasan biaya, berarti topologi-topologi jaringan yang ada bisa disesuaikan dengan keadaan di lapangan.
Topologi jaringan ada beberapa bentuk sebagai berikut:

1. Topologi Bus

Topologi ini adalah topologi yang awal di gunakan untuk menghubungkan komputer. Dalam topologi ini masing masing komputer akan terhubung ke satu kabel panjang dengan beberapa terminal, dan pada akhir dari kable harus di akhiri dengan satu terminator. Topologi ini sudah sangat jarang digunakan didalam membangun jaringan komputer biasa karena memiliki beberapa kekurangan diantaranya kemungkinan terjadi nya tabrakan aliran data, jika salah satu perangkat putus atau terjadi kerusakan pada satu bagian komputer maka jaringan langsung tidak akan berfungsi sebelum kerusakan tersebut di atasi.

Topologi ini awalnya menggunakan kable Coaxial sebagai media pengantar data dan informasi. Tapi pada saat ini topologi ini di dalam membangun jaringan komputer dengan menggunakan kabal serat optik ( fiber optic) akan tetapi digabungkan dengan topologi jaringan yang lain untuk memaksimalkan performanya.

2. Topologi Cincin

Topologi cincin atay yang sering disebut dengan ring topologi adalah topologi jaringan dimana setiap komputer yang terhubung membuat lingkaran. Dengan artian setiap komputer yang terhubung kedalam satu jaringan saling terkoneksi ke dua komputer lainnya sehingga membentuk satu jaringan yang sama dengan bentuk cincin.

Adapun kelebihan dari topologi ini adalah kabel yang digunakan bisa lebih dihemat. Tetapi kekurangan dari topologi ini adalah pengembangan jaringan akan menjadi susah karena setiap komputer akan saling terhubung.

3. Topologi Token Ring

Topologi ini hampir sama dengan topologi ring akan tetapi pembuatannya lebih di sempurnakan. Bisa di lihat dari perbedaan gambar.

Didalam gambar jelas terlihat bagaimana pada token ring kable penghubung di buat menjadi lingkaran terlebih dahulu dan nantinya akan di buatkan terminal-terminal untuk masing-masing komputer dan perangkat lain.

4. Topologi Bintang

Topologi bintang atau yang lebih sering disebut dengan topologi star. Pada topologi ini kita sudah menggunakan bantuan alat lain untuk mengkoneksikan jaringan komputer. Contoh alat yang di pakai disini adalah hub, switch, dll.

Pada gambar jelas terlihat satu hub berfungsi sebagai pusat penghubung komputer-komputer yang saling berhubungan. Keuntungan dari topologi ini sangat banyak sekali diantaranya memudahkan admin dalam mengelola jaringan, memudahkan dalam penambahan komputer atau terminal, kemudahan mendeteksi kerusakan dan kesalahan pada jaringan. Tetapi dengan banyak nya kelebihan bukan dengan artian topologi ini tanpa kekurangan. Kekurangannya diantaranya pemborosan terhadap kabel, kontrol yang terpusat pada hub terkadang jadi permasalahan kritis kalau seandainya terjadi kerusakan pada hub maka semua jaringan tidak akan bisa di gunakan.

5. Topologi Pohon

Topologi pohon atau di sebut juga topologi hirarki dan bisa juga disebut topologi bertingkat merupakan topologi yang bisa di gunakan pada jaringan di dalam ruangan kantor yang bertingkat.

Pada gambar bisa kita lihat hubungan antar satu komputer dengan komputer lain merupakan percabangan dengan hirarki yang jelas.sentral pusat atau yang berada pada bagian paling atas merupakan sentral yang aktiv sedangkan sentral yang ada di bawahnya adalah sentral yang pasif.
