ELI5: Explain Like I'm 5

Open-source computer hardware

Open-source computer hardware means computer parts (like a hard drive, processor, or RAM) that are open-source. This just means that anyone can access the plans and instructions on how to make the part. Usually, the plans are provided online which anyone can access, so anyone can build the parts they need. Open-source computer hardware is usually cheaper than buying the parts in stores, so it can help save people money!
