We have audaciously referred to as our present TeleGeography Explains the Web, however we have by no means correctly defined how the web works and the way bits get pushed across the globe. Till now.
That is proper. We determined it was time to, fairly actually, clarify the web.
Our crew is placing on their professor hats to deliver you the final word five-part explainer particular. We’ll be highlighting the nuts and bolts of how the trade works collectively to deliver you the content material you crave: the net articles, the TikToks, the YouTube movies, and many others.
Our sequence will tackle the questions:
- How does the web work?
- What’s the transport community?
- What are information facilities?

What’s the Web?
Our first episode kicks issues off with a logical query: what’s the web?
Merely put, the web is a community of computer systems.
Computer systems can solely perceive two issues: on and off. Every part that we do on the web is in binary—a sequence of 1s and 0s representing on and off—which supplies directions to your laptop to do all of the wonderful issues it does.
Because of this the very backside of the web is a system for sending these 1s and 0s over wires (or spectrum in some circumstances). No matter you do on the web—e-mail, movies, chats—the knowledge is translated into that binary by your units after which transmitted through packets.
Properly, then. “What’s a packet?” you would possibly ask.
A packet is a bundle of 1s and 0s with a header that tells it the place to go, what kind of knowledge is inside, and any type of particular information about its content material vital for its journey. Every part that goes over the web is separated into packets of knowledge that transfer by the “tubes” of the web.
So, for any of our podcast episodes, my voice is digitized into 1s and 0s. These 1s and 0s are separated into packets, despatched to our podcasting host, then saved, and despatched to you if you end up listening.
These packets then get reassembled so as by your laptop so it seems like I’m speaking to you. (For anybody who thinks our world is devoid of magic if you break all of it down, electrical engineering could make the magic of fantasy look positively banal.)
We cowl tons extra in our first episode, together with laptop networking (Layers 1, 2, and three), protocols, and site visitors change. We additionally invite Vice President of Analysis Tim Stronge to clarify how networks work together with one another. You’ll be able to take heed to the total lesson under and prep for subsequent week after we clarify transport networks.
