- Conclusion
1. The First Computer Bug Was a Real Bug
In 1947, engineers found a moth stuck in the Harvard Mark II computer. They literally “debugged” the machine, and the term “bug” stuck around. This moth is now in the Smithsonian Museum, probably feeling very important.
2. The First Programmer Was a Woman
Ada Lovelace, a 19th-century mathematician, wrote the first algorithm for Charles Babbage’s Analytical Engine. She became the world’s first computer programmer, proving that women have been rocking the tech world long before it was cool.
3. The First Computer Was the Size of a Room
The ENIAC, built in 1945, weighed 27 tons and took up 1,800 square feet. It was less powerful than your smartphone but paved the way for modern computing. Imagine carrying that in your pocket!

4. The QWERTY Keyboard Was Designed to Slow You Down
The QWERTY layout was created to prevent typewriter jams by spacing out commonly used letters. Ironically, it’s still the standard, even though we don’t need to worry about jamming keyboards. Thanks, 19th-century problems!
5. The First Hard Drive Weighed Over a Ton
IBM’s 1956 hard drive, the RAMAC 350, stored a whopping 5MB of data and weighed over a ton. Today, you can store 1 Terrabyte on a tiny memory card or email it to yourself.
6. The Internet Started as a Military Project
ARPANET, the precursor to the internet, was developed in the 1960s by the U.S. Department of Defense. It was designed to keep communication lines open during a nuclear attack. Thankfully, we use it for memes now.
7. The First Email Went Live in 1971
Ray Tomlinson sent the first email to himself as a test. He doesn’t remember what it said, but it probably wasn’t as exciting as your latest spam about discounted Viagra.
8. The First Webcam Watched a Coffee Pot
In 1991, researchers at Cambridge University set up a webcam to monitor their coffee pot. This groundbreaking innovation saved them from unnecessary trips to an empty pot. Priorities, right?
9. The First Mouse Was Made of Wood
Doug Engelbart invented the first mouse in 1964, a wooden block with wheels. It looked more like a kid’s toy than a revolutionary input device, but it worked!
10. The First Virus Was Harmless
In 1971, the “Creeper” virus displayed: “I’m the creeper, catch me if you can!” It didn’t destroy data but annoyed many people. Modern viruses are way less polite (side-eying you MyDoom).
11. Your Smartphone Is Millions of Times Faster Than Apollo 11’s Computer
The Apollo 11 guidance processor had less processing power than a calculator. Your phone could probably land a rocket on the moon while you play Candy Crush.
12. Transistors Are Smaller Than a Red Blood Cell
Modern microprocessors contain billions of transistors, each smaller than a red blood cell. If you think threading a needle is hard, try building one of these chips.
13. The Fastest Supercomputer Can Do 1.7 Quintillion Calculations Per Second
As of 2024, the El Capitan supercomputer can perform 1.742 quintillion calculations per second. That’s like every person on Earth simultaneously solving a math problem over 100 times.
14. Quantum Computers Use Qubits, Not Bits
Quantum computers use qubits, which can be both 0 and 1 together.; this makes them powerful for tasks like breaking encryption or simulating molecules. Don’t worry, your cat videos are safe for now.

15. The First Microprocessor Had 2,300 Transistors
The Intel 4004, released in 1971, had 2,300 transistors. Modern processors have billions. That’s like going from a tricycle to a spaceship in 50 years.
