Internet/Broadband

The World Wide Web

The Internet is a global system of many different interconnected computer networks (the World Wide Web) linked by an array of networking technologies (with a few different layers – application, transport, network and link) using the special TCP/IP protocol and has become a major source of documents, images and multimedia applications providing information throughout the world. It has no single centralized governance and relies solely on IP Addresses, Domain Name Systems and Browser Software to navigate from page to page. Most of the usage today involves watching videos and reading blogs, streaming music, and listening to on-line radio and podcasts.

What is remarkable is that it was developed ONLY in the 1960s but by 2021 nearly 70% of the world populations (5 billion people) has access. [Statistics say that China and the USA are the largest users of the Internet but there are now 1,7 billion web sites; 355 million domain registrations; nearly 4 million mobile internet users; usage of over 6 hours per day per person; and revenue from e-commerce has hit over 4 trillion dollars in 2020.]

Broadband technology has revolutionized the Internet by transmitting multiple signals and traffic types and providing an exceptionally large data carrying capacity (for a given channel quality) at speeds significantly higher than dial up on traditional analogue lines or ISDN PTSN services. The transmission medium can be coaxial cables, optical fibre, radio, twisted pair cables, satellite, power lines or wireless. [Connectivity and Communications RSA (Pty) Ltd. has chosen to use TV White Space wireless technology because of its many technical, location, availability, and economic advantages.]
