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.
2): DSL (or ADSL): This is a specific type of broadband Internet access obtained by connecting a DSL 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).
