In Khan Academy Internet 101 I learned "How the Internet Works", which has various difficult processes to operate on programs. Kahn Academy has introduced me on how the physical infrastructure of the Internet moves information. The Internet is moved through wires, cables, and even through Wi-Fi. I also learned about the IP addresses and DNS which are networks that talk to one another. Then, I learned about the packet, routers, and reliability of Internet that explains how information on the Internet is broken down into packets, and how to ensure that information is reliably received. Then, I discover what HTTP and HTML are used for. The HTTP and HTML are used to describe files and webpages that are sent and received. Furthermore, I studied how cryptography allows for the secure transfer of data online. In this video it explains the 256-bit encryption, public and private kept like SSL & TLS and HHTPS. In the last video I saw on "How the Internet Works" was on cybersecurity and crime which introduces the most common types of cybercrime, including viruses, malware, DDOS attacks and phishing scams.
