What is VPN VPN stands for Virtual Private Network. It is a technology that allows you to create a secure and encrypted connection over the internet from your device to another network. The main purpose of a VPN is to protect your online privacy and security by encrypting your internet traffic and hiding your real IP address, making it harder for anyone to track your online activities or steal sensitive information. VPNs are commonly used by individuals to access restricted websites or to bypass censorship, by businesses to securely connect remote workers to their corporate network, or by travelers to protect their internet connection when using public Wi-Fi hotspots.

Internet Protocol Security  ( IPsec ) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite. It can be used in protecting data flows between a pair of hosts ( host-to-host ), between a pair of security gateways ( network-to-network ), or between a security gateway and a host ( network-to-host ). Some other Internet security systems in widespread use, such as Secure Sockets Layer (SSL), Transport Layer Security (TLS) and Secure Shell (SSH), operate in the upper layers of the TCP/IP mode...

Client to Server VPN-RRAS A virtual private network is a means of connecting to a private network (such as your office network) by way of a public network (such as the Internet). A VPN combines the virtues of a dial-up connection to a dial-up server with the ease and flexibility of an Internet connection. By using an Internet connection, you can travel worldwide and still, in most places, connect to your office with a local call to the nearest Internet-access phone number. If you have a high-speed Internet connection (such as cable or DSL) at your computer and at your office, you can communicate with your office at full Internet speed, which is much faster than any dial-up connection that uses an analog modem. This technology allows an enterprise to connect to its branch offices or to other companies over a public network while maintaining secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link. Virtual private netw...

The definition of a Peer to Peer network is a network that allows two or more computers to share their resources. This can include not just file sharing, but the sharing of individual resources such as hard drives, CD-ROM drives, and printers. In traditional VPNs, there is a designated “server” computer and “client” computers that are accessing resources or files on the server. But in a peer to peer network, the resources of every computer on the peer to peer network are accessible from every other computer on the peer to peer network. So, a VPN peer to peer network is one that shares these resources across a public access, such as the internet. Since peer to peer computers have their own hard drives that are accessible by all computers, you can think of each computer as acting as both a client and a server. VPN Peer to Peer networks would normally be used for sharing content like audio, video, data or anything in digital format. Three major types of peer to peer networks ...
