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 group is placing on their professor hats to convey you the last word five-part explainer particular. We’ll be highlighting the nuts and bolts of how the business works collectively to convey you the content material you crave: the web articles, the TikToks, the YouTube movies, and so forth.
Our sequence will tackle the questions:
- How does the web work?
- What’s the transport community?
- What are knowledge facilities?
- What’s the cloud?
- What’s a WAN?
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. All the pieces that we do on the web is in binary—a sequence of 1s and 0s representing on and off—which provides directions to your pc to do all of the wonderful issues it does.
Which means that 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 data 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 sort of information is inside, and any type of particular data about its content material obligatory for its journey. All the pieces that goes over the web is separated into packets of information 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 when you find yourself listening.
These packets then get reassembled so as by your pc so it feels 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 heaps extra in our first episode, together with pc networking (Layers 1, 2, and three), protocols, and visitors trade. We additionally invite Vice President of Analysis Tim Stronge to clarify how networks work together with one another. You possibly can hearken to the total lesson under and prep for subsequent week once we clarify transport networks.
