If a device sends data to another station on the network and the destination MAC address is not yet 
recorded, ARP is used. An ARP request is broadcast onto the network. All stations on the network 
receive and read the request. The destination IP address for the chosen station is included as part of 
the message so that only the station with this IP address responds to the ARP request....

IP Configuration by DHCP
When an IP-based local area network is installed, each PC must be configured with an IP address. 
If the PCs need to access the Internet, they should also be configured with a gateway address and 
one or more DNS server addresses. As an alternative to manual configuration, there is a method by 
which each PC on the network can automatically obtain this...

Stateful Packet Inspection
Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to 
ensure secure firewall filtering to protect your network from attacks and intrusions. Since 
user-level applications such as FTP and web browsers can create complex patterns of network 
traffic, it is necessary for the firewall to analyze groups of network...

domain name server (DNS) address, and a default gateway address. In most cases, you should 
install TCP/IP so that the PC obtains its specific network configuration information automatically 
from a DHCP server during...
