The first computers were like giant brain machines. They helped people solve problems that took hours or even days to figure out by hand. At first, they didn’t look much like the laptops and phones we use now, some had giant screens and used paper tape to store information! But these early computers made life easier for scientists, engineers, and eventually everyone.
Examples
- Doctors used early computers to help diagnose diseases faster.
- A library used a computer to sort books in seconds.
