ABSTRACT
Networking technology has experienced tremendous development over the past decades. Today, billions of people globally are using networking technology, tens of billions of devices are connected to networks and the internet, and the numbers are growing fast. The technology is quite complex, but most users are not exposed to this. When a user switches on their laptop, a series of networking technologies is automatically initiated to ensure that the laptop gets an Internet Protocol (IP) address and that the network communication is secure. The IP is the common denominator in network technology, and although it was originally designed for military communications, today it is also used in small home networks, enterprise local area networks (LANs), and the internet for applications such as email, web browsing, telephony, and network video.
