Html is on the surface but underneath HTML is TCP-IP: I thought I would share a little about this because many people don't know about it

When I was learning to be a network engineer before I had to retire because of a Heart virus I was learning more about TCP-IP. In order to have an internet that actually works you need more than HTML which tells computers how to configure web pages. So, the foundation upon which HTML and compatible languages are built is actually TCP-IP for sending packets of information all over the world.

What You Need to Know About the TCP/IP Transport Layer

TCP/IP (Transmission Control Protocol/Internet Protocol) is the foundational suite of communication protocols used to interconnect network devices on the internet and private networks. It dictates how data is broken into packets, addressed, transmitted, routed, and received.

The suite is divided into four specific abstraction layers:

Application Layer: Interacts directly with software applications to format and present data (e.g., HTTP for web browsing, SMTP for email).

Transport Layer: Establishes connections and ensures data is reliably delivered. TCP guarantees that packets arrive in the correct order without errors, while UDP provides faster, less reliable transmission.

Internet Layer: Responsible for logical addressing and routing. The Internet Protocol (IP) assigns addresses to devices and determines the optimal path for data across networks.

Network Access Layer (or Link Layer): Handles the physical transmission of data hardware, such as Ethernet cables or Wi-Fi.

For a deeper dive into the technical specifications and protocol interactions, you can read the IBM Transmission Control Protocol/Internet Protocol Documentation or explore how data is encapsulated on Cloudflare's TCP/IP Overview.
