Pengaturan Protokol dalam KomunikasiPengaturan Protokol dalam Komunikasi

1. Client-Server : sistem dibagi menjadi komponen yang berfungsi sebagai peminta layanan (client) dan pemberi layanan (server).

2. Peer-to-Peer : sistem terdiri atas komponen- komponen yang fungsinya setara dan dapat saling

melayani atau meminta laya nan .

Pada prinsipnya , arsitektur peer-to-peer juga merupakan arsitektur client-server dimana setiap komponennya dapat mempunyai fungsi sebagai client sekaligus server terhadap komponen lain.

Layanan Application LayerLayanan Application Layer4. DHCP-Dynamic Host Configuration Protocol

Merupakan protokol yang dipakai untuk memberikan IP address secara dinamis kepada client.

Jika Non DHCP, pemberian IP address dilakukan secara manual ke setiap komputer.

Jika Menggunakan DHCP, seluruh komputer yang tersambung di jaringan akan mendapatkan IP address secara otomatos dari srver DHCP.

Selain IP address, banyak perameter jaringan yang dapat diberikan oleh DHCP , seperti default gateway dan DNS server.
