Users will generally use the following network types and hardware:
1): Local Area Network (LAN): An internal network usually operated via a hub, a switch, or a router and
will usually operate within an office or household via wireless or Ethernet cable connections.

or ADSL modem (or modem/router) to a normal telephone cable, and setting up an Internet account
with an Internet Service Provider (ISP) such as AT&T or AOL.
3): Port Forwarding: This allows external connections to pass through security settings on routers and
firewall devices. Ports need to be allows in, and then directed to the specific IP address of the
computer or device that the connection is intending to reach.
4): Router: This is a device that connects 2 separate networks (most commonly a LAN to the Internet)
and comes with built in security options and allows multiple devices to connect to a LAN and gain
Internet access (if the router is connected to a modem).
