Communication

Communication has four components: sender,

receiver, message, and medium. In networks, devices

and application tasks and processes communicate

messages to each other over media. They represent

the sender and receivers. The data they send is the

message. The cabling or transmission method they

use is the medium.

Connection

In networking, two devices establish a connection to

communicate with each other.

DHCP

Developed by Microsoft, DHCP (Dynamic Host

Configuration Protocol) is a protocol for assigning

dynamic IP addresses to devices on a network. With

dynamic addressing, a device can have a different IP

address every time it connects to the network. In some

systems, the device's IP address can even change

while it is still connected. It also supports a mix of static

and dynamic IP addresses. This simplifies the task for

network administrators because the software keeps

track of IP addresses rather than requiring an

administrator to manage the task. A new computer can

be added to a network without the hassle of manually

assigning it a unique IP address. DHCP allows the

specification for the service provided by a router,

gateway, or other network device that automatically

assigns an IP address to any device that requests one.

DNS

Domain Name System is an Internet service that

translates domain names into IP addresses. Since

domain names are alphabetic, they're easier to

remember. The Internet however, is really based on IP

addresses every time you use a domain name the

DNS will translate the name into the corresponding IP

address. For example, the domain name

www.network_camera.com might translate to

192.167.222.8.

Enterprise

An enterprise network consists of collections of
