1: please describe the following and share which you plan to apply to your scenario?

• Packet-filtering router firewall system
• Screened host firewall system
• Screened-Subnet firewall system

2: I believe the Internet is a computer network linking smaller computer networks worldwide. It would include commercial, educational, governmental networks, which use the same set of communications protocols. Intranet is a private network used only within the company or organization. My understanding of Extranet is it allows controlled access from the outside on the computer network.

3: A local area network is a network that connects computers and other devices in a relatively small area, such as single building or a group of buildings. It usually connects workstations and personal computers and enables users to access data and devices such as printers and modems on the network. A wide area network is a network which can span a relatively large area and consists of two or more local area networks.
