NetComm NP643 manual Csma/Ca, Csma/Cd, Dhcp

Channel:	The bandwidth which wireless Radio operates is divided into
	several segments, which we call them “Channels”. AP and the client
	stations that it associated work in one of the channels.
CSMA/CA:	In local area networking, this is the CSMA technique that combines
	slotted time -division multiplexing with carrier sense multiple access/
	collision detection (CSMA/CD) to avoid having collisions occur a
	second time. This works best if the time allocated is short compared
	to packet length and if the number of situations is small.
CSMA/CD:	Carrier Sense Multiple Access/Collision Detection, which is a
	LAN access method used in Ethernet. When a device wants to
	gain access to the network, it checks to see if the network is quiet
	(senses the carrier). If it is not, it waits a random amount of time
	before retrying. If the network is quiet and two devices access
	the line at exactly the same time, their signals collide. When the
	collision is detected, they both back off and wait a random amount
	of time before retrying.
DHCP:	Dynamic Host Configuration Protocol, which is a protocol that lets
	network administrators manage and allocate Internet Protocol
	(IP) addresses in a network. Every computer has to have an IP
	address in order to communicate with each other in a TCP/IP based
	infrastructure network. Without DHCP, each computer must be
	entered in manually the IP address. DHCP enables the network
	administrators to assign the IP from a central location and each
	computer receives an IP address upon plugged with the Ethernet
	cable everywhere on the network.
