What Is Internet?
It is not easy to define what internet and although we may perceive it as a collection of computers and servers with human elements and non-human elements communicating there is more than that. We can make the internet to be what we want. We can shape it or mold it. The internet is a form of network that allows computer networks situated around the world to be able to talk to each other. Internet comprises of components like cables, computers, routers, data centers, repeaters, Wi-Fi towers, and satellites ensuring that digital information is able to travel around the globe.
The internet started with the U.S. government when it built a network of computers known as ARPANET in the 1960s. The U.S. National Science Foundation (NSF) began NSFNET, a university network backbone in 1985. In 1995, NSFNET was replaced by other networks that were operated by commercial internet companies. It is at this point when the internet was taken to the public on a bigger scale.
How does Internet Work?
Unlike telephone networks that in most cases were run by sole companies, with the internet, it comprises of thousands of networks that are interconnected and rub by service providers, governments, individual companies, universities and other parties. Through open standards, the internet is able to communicate and this is why you find that you can create content, you can offer services, or you can sell products without asking for permission from a particular central authority.
Who Makes The Internet Work?
Many communities and organizations help develop and evolve the internet ecosystem. The continued evolution and growth or development of the internet and its adoption is attributed to the different parties that are involved. For example, there are people and organizations can involve in offering discovering and offering open, transparent as well as collaborative processes. There are also organizations that provide use of infrastructure through dispersed control and ownership.
Applications and Network Technologies of the Internet:
The backbone and the primary component of the internet communication is the internet protocol (IP). Since the internet is made up of layers of software and hardware, IP communication standard allows the users to have address schemes and pin point unique connected devices. There are various IP versions that are used for internet communication today including Internet Protocol version 4 (IPv4) as well as Internet Protocol version 6 (IPv6).
The internet is also the most cost-effective method of communication in the globe. Through the internet, we have the following services being offered:
- Online gaming and movies.
- Web-enabled audio.
- Video conferencing services.
- Instant messaging.
- Data transfers and file sharing mostly done through File Transfer Protocol (FTP).
- Social networking.
- Financial services.
- Online shopping.
- Internet forums.
How Big Is The Internet?
You can measure the internet using the information that moves through it. For example, about 5 Exabyte’s of data move through the internet every day and that translates to about 40,000 two-hour movies per second. To ensure this kind of communication, it requires substantial infrastructure like wiring. There are cables that run thousands of miles crisscrossing different countries. For example, about 300 submarine cables running under the deep sea with thickening of a garden hose and they are a kingpin of the internet communication. These cables bundle up hair-thin fiber optics carrying data at immensely high speeds. For instance, 12,000-mile cable that acts as the Asia-America Gateway connects California to Singapore and Hong Kong among other locations in Asia.
