ELI5: Explain Like I'm 5

Macroelectronics

Macroelectronics is like having a lot of little computers all working together to do something big. Just like how you and your friends can work together to build a big fort out of blocks, lots of tiny gadgets called "microchips" can work together to make a big electronic device like a computer or a phone. These microchips have tiny little parts inside of them that can send and receive information, like little messengers carrying messages to and from different parts of the device. When all the microchips work together, they can make the device do all sorts of cool things like play games, send messages, or make phone calls. Macroelectronics is all about figuring out how to use lots of microchips together to make really powerful electronic devices.
