The Entwined World of Internet and Related Technologies

Internet is a global system of interconnected networks using certain protocols to serve and connect billions of users around the world. Internet is a network of networks to which millions of global as well as local public, private, business, educational, and government networks are connected. Internet has turned the world of connectivity and knowledge sharing radically, and is certain that it will amaze us with new facilitations in the future.
The research and development of Internet was initiated in the early 1960s, with initial research carried on packet switching and packet switched networks. From that time on, vigorous research and development activities about Internet was carried out by different persons and organizations. And today, it has reached advanced levels, far exceeding our assumptions and expectations. Internet was not available commercially until the late 1980s and early 1990s when certain Internet Service Providers (ISPs) emerged in the US, Europe, and Australia.
Internet and World Wide Web are often considered to be the same, but that is not the case; Internet maintains a global communication system between computers, wherein World Wide Web is a collection of resources linked by URLs that uses the Internet to access and communicate. Since its commercialization, the Internet has invaded almost all the fields right from communication methods like email, instant messaging, and two-way interactive video calls, to discussion forums, blogs, social networking, and online shopping sites.
Internet access was initially provided by the dial up method, and from that it has now moved to advanced levels such as broadband, Wi-Fi, satellite, and 3G/4G technologies.

Of these Internet Access technologies, the most commonly used one nowadays is the broadband technology. People often tend to use a technology available in the marketplace without even knowing the basic principle behind its functioning and what it is all about. So for all those people, let us first answer the question, what is broadband?
Broadband refers to a multi-frequency communication with larger bandwidth. Broadband Internet service provides high data rate access, and supports bit rates higher than 56 kilobytes per second, and is also known as high-speed Internet. This type of Internet service provides access to faster World Wide Web browsing, telephony, video conferencing, virtual private networks, and live streaming of events. By the 21st century, broadband Internet access became commercially available. There are many types of broadband connections available in the marketplace, namely: Landline Broadband, Mobile Broadband, Power-Line Broadband, ISDN, Satellite Broadband, and Wi-Fi, among others.
As the commercial usage of Internet is on the ascendency, the need for high-speed Internet access and data accessed via the Internet has also gone up. The field of Internet service provision has evolved over the past two decades, right from dial up connections to today's Wi-Fi and broadband connections. Overall Internet usage around the world has seen enormous growth, and for the time period between 2000 and 2009, it was estimated that Internet users across the globe grew five folds from about 4 million users to about 2 billion users. As the reliance on Internet grows, the need for it to evolve is certainly a necessity. Internet will certainly live on for many more centuries to come and it is sure that it will undergo even more radical changes to suit the present Internet dependent world.
