TRENDnet TV-IP322P manual Communication, Connection

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.
