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 network
An enterprise network consists of collections of networks connected to
each other over a geographically dispersed area. The enterprise network
serves the needs of a widely distributed company and operates the
company’s mission-critical applications.
