TCP/IP
Transmission Control Protocol/Internet Protocol (TCP/IP) comprises
the backbone of the Internet. IP moves packets of data between
nodes while TCP verifies delivery from client to server. The device
you hook up to your wireless access point will identify itself with an IP
address so that the network will know where to retrieve and deposit
requested information.
Static IP Address
A static IP address is a fixed address that is assigned manually to a
device on the network. Static IP addresses must be unique and
cannot be shared, therefore they are used in situations where the
address should never change, like print servers or PC servers.
Dynamic IP Address
A dynamic IP address is a temporary IP number, dynamically or
randomly generated by a DHCP server. The address lasts only as
long as the server allots, usually in the space of a day or two. When
the IP address expires, the client is automatically reassigned a new
IP address, ensuring smooth communication.
