Study Notes

Internet Basics

The first form of Internet is the ARPANET, a network created by the US Department of Defense in 1969.
The World Wide Web (WWW) was introduced by Tim Berners-Lee using the protocol HTTP (Hypertext Transfer Protocol) in 1989.

Internet Governance

The Internet Corporation for Assigned Names and Numbers (ICANN) was established in 1998 to oversee the global domain name system.

Networks

An Intranet is a private computer network that is not accessible to the general public.
Hardware requirements for Internet connectivity include a computer, modem, and router, while software requirements include an operating system, web browser, and TCP/IP protocol.

Internet Connectivity

There are two ways to connect to the internet: dial-up connection and broadband connection.
The protocol used for direct connection to the ISP (Internet Service Provider) is PPPoE (Point-to-Point Protocol over Ethernet).
Fiber optics technology uses optical fibers for data transmission to provide high-speed internet connection.
Satellite broadband requires a satellite dish, modem, and router to access the internet.
Wi-Fi technology uses radio waves to transmit information across a network in a range of 2.4 GHz to 5 GHz over short distances.

Li-Fi and Internet Services

The main component of Li-Fi (Light Fidelity) network for data transmission is light.
WWW stands for World Wide Web in the context of internet services.
A browser enables users to access and view websites on the internet.
DNS (Domain Name System) translates domain names into IP addresses, enabling users to access websites by their domain names rather than IP addresses.
TCP (Transmission Control Protocol) connection enables the browser to establish a reliable, error-checked connection with the web server, ensuring data integrity.
