ELI5: Explain Like I'm 5

Williams tube

Hey kiddo! Have you ever heard of a Williams Tube? It's a really old device that was used to store information way back in the day, before we had modern computers like the one we have now.

Imagine having a piece of paper with a bunch of letters and numbers written on it. You can read what's on the paper, right? Well, the Williams Tube was kind of like that, except it was made out of glass and it used electric signals instead of ink.

Inside the tube, there were tiny dots called "electronic spots." These spots could be turned on or off, like little light bulbs. When they were turned on, they would glow and show a little dot of light.

Now, let's say you wanted to store some information in the Williams Tube. You could turn on certain spots to represent the letters or numbers you wanted to store. For example, if you wanted to store the number "5," you could turn on a few spots to create the shape of the number "5."

When you wanted to read the information that was stored in the Williams Tube, you could shine a beam of electrons on the spots. The spots that were turned on would glow and show you the information that was stored. It was kind of like shining a flashlight on a piece of paper to read what's written on it.

The Williams Tube was a really important invention at the time because it allowed people to store information electronically, which was a huge advancement compared to storing information on paper or in books. But now, we have much more advanced ways of storing and processing information, like the computer we use today.

So that's a little bit about what the Williams Tube is and how it works. I hope that makes sense to you, kiddo!
