See The 10 Best Corded Phones on Ezvid Wiki ►►
Fact #1. Corded phones can work with next to no power. In fact, the requirements are so low that it's supplied to you by your phone company. They probably do bill you for it. But their systems have plenty of battery generated fail safes. The power could go out for days in your neighborhood. You'd still be able to reach out to someone.
Fact #2. Phones are incredibly simple. The basic idea is the same as putting a string between two cans. That doesn't account for newer innovations like caller ID. But a phone basically takes your voice and translates its vibration into a digital signal. Then sends it across a long stretch of copper wire. Those vibrations are then translated back into their original form through a small speaker.
Fact #3. They aren't just for nostalgia. The fact that they can run without power is important. But so is their tactile nature. Using a corded phone is fundamentally different from a cellular phone. Especially smartphones. They keep you grounded. And their form produces memories of specific places. Those memories last a lifetime.
Fact #4. Without corded phones, there would be no Internet. That's true in a number of ways. For one, the telephone was fundamentally about allowing communication at a distance. That's the entire premise of the Internet as we know it. People had been figuring out ways to do that for a long time. Because of corded phones, they figured it out.
Fact #5. Dial up modems used phone lines. That's the second way they matter. The world wide web was literally developed on the infrastructure of corded phones. Even older millenials will remember having to choose between the phone and the Internet. Or making their parents choose, at least.
