Internet Protocol Security, short for IPSec, is a suite of protocols for securing communications across the TCP/IP stack. This suite is based on the use of mathematical functions along with encryption and authentication algorithms to ensure the privacy, integrity, and authenticity of information from each IP packet transmitted on the network.

A Virtual Private Network, or a VPN as it most commonly called, is a private tunnel that connects two or more networks over the Internet. The way a VPN works is by linking the two networks as if they are directly connected and secured the traffic between them by encryption, ensuring data integrity and data authentication. A virtual private network expands a private network over a public network...

A routing protocol is an algorithm that gives a Router the ability to learn (dynamically) about specific existing networks around it (or even the Internet). Practically, these routing protocols help routers learn dynamically about each other without the need for an administrator to intervene. This helps us primarily because it does not require an administrator to set up each network individually...
A network is an assembly of interconnected devices (PCs, servers, mobile devices, routers, switches and so on) that can communicate (exchange information) with each other. Networks can be of several types: 1. LAN or a Local Area Network, such as your home network connected through cable. 2. MAN or a Metropolitan Area Network such as an extended network between computers on the surface of a city 3...
