Introduction to Internet
The Internet is a global network of billions of computers and other electronic devices. With this, it’s possible to access almost any information, communicate with anyone else in the world, and do much more. You can do all of this by connecting a computer to the Internet, which is also called going online. When someone says, a computer is online, it’s just another way of saying it’s connected to the Internet.
It’s important to realize that the Internet is a global network of physical cables, which can include copper telephone wires, TV cables, and fiber optic cables. Even wireless connections like Wi-Fi and 3G/4G rely on these physical cables to access the net. When you visit a website, your computer sends a request over these wires to a server. A server is where websites are stored, and it works a lot
like your computer’s hard drive. Once the request arrives, the server retrieves the website and sends the correct data back to your computer. What’s amazing is that this all happens in just a few seconds.
What is Internet ?
The Internet has revolutionized the computer and communications world like nothing before. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. It’s at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location.
It’s represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure. Beginning with the early research in packet switching, the government, industry and academia have been partners in evolving and deploying this exciting new technology.
Today, terms like “[email protected]” and “http://www.acm.org” trip lightly off the tongue of the random person on the street.
The Internet today is a widespread information infrastructure, the initial prototype of what is often called the National (or Global or Galactic) Information Infrastructure. Its history is complex and involves many aspects – technological, organizational, and community.
And its influence reaches not only to the technical fields of computer communications but throughout society as we move toward increasing use of online tools to accomplish electronic commerce, information acquisition, and community operations. (Leiner et al, 2017)
It’s works because open standards allow every network to connect to every other network. This is what makes it possible for anyone to create content, offer services, and sell products without requiring permission from a central authority.
It levels the playing field for everyone and it’s the reason why we have a rich diversity of applications and services that many of us enjoy today.
The Internet is a network of networks that needs to operate around the world as if it were one. Like policy, the technical coordination of the Internet has common characteristics:
Run by a non-profit membership organizations that work together to meet the needs everyone. (Peterson and Welch, 2003)
This self-regulation has been the key to the successful growth of the Net and is flexible enough to adapt to changing future needs.

The overall responsibility for managing Internet Protocol address or domain names at upper levels is vested in the Internet Assigned Numbers Authority (IANA), which delegates the actual administration of most functions to other bodies.
At global regional levels, the principal bodies providing allocation and registration services that support the operation of the Internet globally are:
Réseaux IP Européens Network Coordination Centre
- American Registry for Internet Numbers
Asia Pacific Network Information Centre
Latin American and Caribbean IP address Regional Registry
African Regional Registry for Internet Number Resources
The operations are coordinated worldwide through the Internet Engineering Planning Group (IEPG), an Internet operational group intended to assist Internet Service Providers to interoperate within the Global Internet.
At global regional levels, bodies active in coordinating operations include the:
American Registry for Internet Numbers; Manages the Net numbering resources for North America, a portion of the Caribbean, and sub-equatorial Africa.
Asia Pacific Networking Group (APOPs); Promotes the Internet and the coordination of network inter-connectivity in the Asia Pacific Region. (Peterson and Welch, 2003)
Internet network security is significantly facilitated by a number of Computer Emergency Response Teams (CERTs) in eight countries and within a number of service provider operations and private networks. They were formed to continually monitor the network for security incidents, serve as a repository for information about such incidents, and develop responsive advisories.
