# Introduction {% embed url="" %} Slides {% endembed %} ### What is the Internet? Before we learn what the Internet is, we need to understand what a *Network* is. A network is a group of computers or other devices which are connected to each other. For example, you at your home might have a network of computers and devices. Your friend living next door might have a similar network of devices. The Internet is a global network of computers connected to each other that communicate through a standardized set of protocols. * **Packet:** A small unit of data that is transmitted over the internet. * **Router:** A device that directs packets of data between different networks. * **IP Address:** A unique identifier assigned to each device on a network, used to route data to the correct destination. * **Domain Name:** A human-readable name that is used to identify a website, such as google.com. * **DNS:** The Domain Name System is responsible for translating domain names into IP addresses. * **HTTP:** The Hypertext Transfer Protocol is used to transfer data between a client (such as a web browser) and a server (such as a website). * **HTTPS:** An encrypted version of HTTP that is used to provide secure communication between a client and server. * **SSL/TLS:** The Secure Sockets Layer and Transport Layer Security protocols are used to provide secure communication over the internet. ### Wires, Cables, and Wi-Fi Information on the Internet moves from one computer to another in the form of bits over various mediums, including Ethernet cables, fiber optic cables, and wireless signals (i.e., radio waves). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
