A network can be defined as a group of computers and other devices connected in some ways so as to be able to exchange data.
Each of the devices on the network can be thought of as a node; each node
has a unique address. -Addresses are numeric quantities that are easy for
computers to work with, but not for humans to remember. Example: 204.160.241.98
Some networks also provide names that humans can more easily remember than
numbers. Example: http://www.javasoft.com, corresponding to the above numeric
address. NIC addr1 NIC addrN NIC addr2 …
· Clients and servers—how services such as e-mail and web pages connect
using networks.
· IP addresses—how devices on a network can be found.
· Network hubs, switches and cables—the hardware building blocks of any
network.
· Routers and firewalls—how to organize and control the flow of traffic on
a network.
