Networking

Virtual Private Networks (VPNs) are used to allow a remote public connection to an internal network. A VPN is essentially a virtual tunnel connecting a remote user (Tunnel Vision). The traffic within the VPN tunnel is encrypted, and there are two ways to do this. One way is Internet Protocol Security (IPsec) and the other is Secure Sockets Layer (SSL).

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

There are 9 IEEE 802.11 services in total which can be classified into to categories:

IP stands for ‘Internet Protocol’ and is made of numbers and periods. It is the

Each IP that accesses the internet will be under a NAT protocol to help protect the users accessing the internet.

A VPN is a private network that uses a public network (usually the Internet) to connect

VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

36. The two-factor authentication generally combines “something you have” and “something you know” or “something you have” and “something you are.”

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.

Physical media is what physically connects the computers connected on the internet. For this network two physical media will be used to allow access to the application layers of the system. The coaxial cables will be used to create a WAN. While a wireless protocol will be used in allowing users to roam within the network. A LAN will be represented as follows;

WiMAX, is an abbreviation of “Worldwide Interoperability for Microwave Access”. WiMAX is a telecommunication standards designed to enable the wireless transmission of data in a variety of ways. It supports the transmission of voice, video, Voice Over IP (VOIP), data, as well as several multimedia applications. WiMAX provides wireless broadband services alternative to cable and digital subscriber line (DSL). Also, it provides mobile communication and wireless broadband services

Router ID: In OSPF this is a unique 32-bit number assigned to each router used to identify themselves and others in the LSDB.
