Internet History and Definition

Study Notes

The internet is a global system of interconnected computer networks that use the Internet Protocol (IP) to link devices worldwide.
The internet has its roots in the 1960s, when the United States Department of Defense's Advanced Research Projects Agency (ARPA) funded a project to create a network of computers that could communicate with each other.
The first network, called ARPANET, was developed in 1969.
The internet as we know it today began to take shape in the 1980s, with the development of the Internet Protocol (IP) and the Domain Name System (DNS).

Network Access Points (NAPs): high-speed networks that connect to the internet backbone.
Internet Backbone: high-speed networks that connect major nodes and exchange points.
Internet Service Providers (ISPs): companies that provide internet access to customers.
Domain Name System (DNS): a system that translates domain names to IP addresses.

Client-Server Architecture: clients (e.g., web browsers) request data from servers, which provide the data.
Packet Switching: data is broken into small packets, each routed through the internet to reach its destination.
IP Addresses: unique addresses assigned to each device on the internet.

TCP/IP (Transmission Control Protocol/Internet Protocol): a suite of protocols that govern data transmission over the internet.
HTML (Hypertext Markup Language): a markup language used to create web pages.
HTTP (Hypertext Transfer Protocol): a protocol used for transferring data over the internet.

World Wide Web (WWW): a system of interlinked hypertext documents, accessed via web browsers.
Email: a system for sending and receiving electronic mail.
File Transfer Protocol (FTP): a protocol used for transferring files over the internet.

Internet Corporation for Assigned Names and Numbers (ICANN): a non-profit organization that oversees the global domain name system.
Internet Governance Forum (IGF): a multi-stakeholder forum that discusses internet governance issues.
