Alright, so you've got yourself internet service! Some wires slam into your home, get stuck in a box, and boom, internet! Heck, maybe you even have a fancy modem-router combo box! But, well- what is a modem? Hell, what's a router? And why is there an eth- in my -ternet?

EPISODE NOTES/MISTAKES: We mentioned that DOCSIS and EuroDOCSIS are different due to regions using NTSC or PAL (North America vs. Europe). NTSC has been depreciated in the move from analog to digital television, replaced with ATSC. Similarly, PAL is replaced by DVB. Japan actually uses ISDB, as does South America and the Philippines.

Cat7 is backwards compatible, it just has not received a stamp of approval from the IEEE (Insitute of Electrical and Electronics Engineers) or the Electronic Industries Alliance (EIA). This has left very few developers to create support for the GG45 connector that Cat7 uses.

802.11ad refers to WiGig, and was never retroactively turned into "Wi-Fi 5". It is a separate standard that has high bandwidth, low latency, but poor wall penetration.
