This is The World's Smallest Computer

At first you might think of this famous picture. But that isn't actually a computer. It's a set of 128 IBM computers. Just 1 of those computers in a pile of salt, looks like this, and can run Doom. But until 2022, those were actually the smallest computers.

Now, scientists have made one a lot smaller.

It's made by a team at the University of Michigan. And their goal is to get computers small enough to fit in biological cells. This is what they have so far. A tiny computer programmed by flashing light in a pattern. Some of them even have image sensors. And compared to a grain of rice, this is what it looks like.

But because it's so small, you could easily think that

In many ways, our memories make us who we are, helping us remember our past, learn and retain skills, and plan for the future. And for the computers that often act as extensions of ourselves, memory plays much the same role. Kanawat Senanan explains how computer memory works.

Savvies, here's a way to stop your Windows 10 or 11 computer from slowing down or freezing.

We're going to take a look inside a typical computer and show you some of the main components. We'll show you what these components look like in a laptop and a desktop computer, and we'll also talk about some of the differences between laptops and desktops.

We hope you enjoy! To learn more, check out our written lesson here: https://edu.gcfglobal.org/en/c....omputerbasics/inside

0:12 Motherboard
0:24 CPU
0:36 Heatsink
0:45 RAM
1:03 Hard drive
1:21 Expansion slots
1:41 Power supply unit

Where are the limits of human technology? And can we somehow avoid them? This is where quantum computers become very interesting.
