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.
In networking, two devices establish a connection to
communicate with each other.
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.
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
