The Internet Revolution is the New Industrial Revolution



- The Internet:  The Largest Network of All

The Internet is the largest computer network. It is composed of thousands of smaller networks and connects billions of devices worldwide, handling the majority of data communication that occurs on a daily basis. The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The mobile Internet, automation and Artifical Intelligence (AI) will have profound implications - for jobs, infrastructure, investment, global competition and more.


- The Internet and Beyond

Initially restricted to military and academic institutions, the Internet now operates on a three-level hierarchy composed of backbone networks, mid-level networks and stub networks. It is a full-fledged conduit for any and all forms of information and commerce. Internet websites now provide personal, educational, political and economic resources to virtually any point on the planet.

The Industrial Internet is the next frontier. It merges the physical with the digital to predict, control and create systems that produce better outcomes. Through the Industrial Internet, companies will shift from responding to events and will instead use connected machines, big data and analytics to predict and plan, resulting in large gains in industrial productivity, bottom line results and societal outcomes.

The Fourth Industrial Revolution (Industry 4.0) refers to the marriage of physical assets and advanced digital technologies, the Internet of Things (IoT), artificial intelligence (AI),  robots, drones, autonomous vehicles, 3D printing, cloud computing, nanotechnology, and more - that communicate, analyze, and act upon information, enabling organizations, consumers, and society to be more flexible and responsive and make more intelligent, data-driven decisions.

People around the world are accessing the Internet with mobile devices. The number of connected devices is soaring. Soon machines will be communicating with each other in the Internet of Things. To progress the development of the digital society and make the Internet of Things working, we need a powerful wireless network that can transfer large volumes of data fast. Wireless 5G will substantially improve the mobile Internet. LTE is currently the fastest mobile technology available, supporting peak data rates of up to 300 megabits per second (Mbs). Even after the introduction of 5G LTE will still be available for consumers.


- Intranet:  A Secure Internet-like Network for Organizations

With advancements in browser-based software for the Internet, many private organizations have implemented Intranets. An Intranet is a private network utilizing Internet-type tools, but available only within that organization. For large organizations, an Intranet provides easy access to corporate information for designated employees.


- Extranet:  A Secure Means for Sharing Information with Partners

While an Intranet is used to disseminate confidential information within a corporation, an Extranet is commonly used by companies to share data in a secure fashion with their business partners. Internet-type tools are used by content providers to update the extranet. Encryption and user authentication means are provided to protect the information, and to ensure that designated people with the proper access privileges are allowed to view it.
