¥ 1. An IP address is an identifier for devices on a TCP/IP network. Usually, an IP address could be assigned using a 32-bit numeric address written as four numbers separated by periods. Each number can go from being zero to 255. For example, 1.160.10.240 could be an IP address. Although IP address can be static or dynamic. A static IP address stays the same and it is a permanent Internet address. On the other hand, a dynamic IP address is a temporary address that is assigned each time a computer or device accesses the Internet, and DNS is used to it make easy to read or remember hostnames like www.it200class.com

VPNs are most often used by corporations to protect sensitive data being compromised by hackers.
¥ 1.4 Firewalls A firewall is a network security system, either hardware- or software-based, that uses rules to control incoming and outgoing network traffic. A firewall acts as a barrier between a trusted network and an untrusted network. A firewall controls access to the resources of a network through a positive control model. This means that the only traffic allowed onto the network is defined in the firewall policy, and all other traffic is denied.
¥ 1.5 LAN versus WAN LAN, which stands for local area network, and WAN, which stands for wide area network, are two types of networks that allow for interconnectivity between computers. As the naming conventions suggest, LANs are for smaller, more localized networking than in a home, business, school, etc. WANs cover larger areas, such as cities, and even allow computers in different nations to connect. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. And while LANs tend to be owned, controlled and managed in-house by the organization where they are deployed, WANs typically require two or more of their constituent LANs to be connected over the public Internet or via a private connection established by a third-party telecommunications
