I’ve met quite a few non technical people who assume the Internet is carried by satellite.
- antjanus 8y agothat was my own assumption until I learned about the under sea cables.
- closeparen 8y agoI distinctly remember "learning" this in K12, before getting deeper into the technology industry. One of our textbooks had a diagram with lines showing signals flowing from continent to satellite to continent. It wasn't until I got deeper into the industry that I learned satellite latency is awful, bandwidth is limited, and everyone uses cables or microwave point-to-point links when they can. (Actually, the role of those point-to-point links is drastically undersold for how ubiquitous they are in our cities. Worked with some Ubiquiti gear professionally once, and now notice them everywhere).
- cbg0 8y agoIt's actually a very reasonable assumption, as most people don't really know about the limits of fiber, but they do own mobile phones which seem to work almost wherever they are thanks to wireless technology.
- ekianjo 8y agoIt's not reasonable once you consider the bandwidth of satellites.
- Moru 8y agoAnd the delay
- kiallmacinnes 8y ago"Normal" people don't know that kinda stuff.. Let's be honest, they make many of their assumptions from TV and Movies - and often those disaster movies focus on the world grinding to a halt because "the satellite network is down" (I do the same with other industries!)
