It depends on what you mean. Learning ISA's is easy. Learn a few different assembly languages, write a disassembler and maybe an assembler for one of them, which will require you to study the documentation. Intel has a ton. There's a ton on RISC. I assume the same is true for ARM, PowerPC and older simpler architectures. Maybe start with the 6501 then an 8086. To go deeper, there are plenty of CS books and video courses online that cover those subjects more theoretically.
Designing and manufacturing? How deep do you want to go? If you just want to know the basics then YouTube has everything you need. If you want to be involved, then you'll want to get an education in that specifically. It's not something you can just learn at home.
Are you sure about that? There have been thunderstorms all over the Middle East this week. It was flooding in Oman a few days ago and today it's raining in Iran. There's video of the lightning from various places.
basically every app is a tab. this is how I run i3wm. full screen tabbed layout. smaller modal windows still appear in their normal smaller windows in front of the current full screen app.
5G and 4G are not terms applied to WiFi. We have 802.11a/b/g/n/ac/ax and WiFi6/7
WiFi operates in the 2.4, 5, 6GHz bands, but those frequency bands are not used to differentiate WiFi standards because you can mix and match WiFi 6/7 on all three bands.
There are also more WiFi bands below 2.4 and above 6GHz, but they're not common worldwide.
I know that, but you misunderstand. This is a 4G model and WiFi router in one. The company that made it is pretending there's something called "5G WiFi" though.
