By IDTeamComputers have become an essential part of our lives, from smartphones to supercomputers, changing the way we work, communicate, and explore the world. But did you know that the first computer was the size of a room? Or that the first computer virus was created as a joke? There are many fascinating and lesser-known facts about computers that will leave you amazed!
In this article, we will explore some of the most interesting facts about computers, covering history, innovations, and technological breakthroughs.
1. The First Computer Was as Big as a Room
The ENIAC (Electronic Numerical Integrator and Computer), built in 1945, was the first fully electronic general-purpose computer. It weighed about 27 tons, occupied 1,800 square feet, and used 18,000 vacuum tubes! Today, we carry computers in our pockets that are millions of times more powerful.
2. The First Computer Virus Was Created as a Joke
The first-ever computer virus, called the Creeper Virus, was developed in 1971 by Bob Thomas. It displayed the message, “I’M THE CREEPER, CATCH ME IF YOU CAN!” It didn’t cause harm but instead replicated itself across computers. This led to the creation of the first antivirus software, called Reaper, which removed the virus.
3. The World’s First Website Is Still Online
The first website in history, info.cern.ch, was created by Tim Berners-Lee in 1991 at CERN. The site contained information about how the World Wide Web (WWW) worked and is still accessible today.
4. The First Computer Mouse Was Made of Wood
The first-ever computer mouse, invented by Douglas Engelbart in 1964, was made of wood! It had a single button and was far from the sleek, ergonomic designs we use today.
5. More Than 90% of the World’s Currency Exists Digitally
It’s estimated that only 10% of the world’s money exists as physical cash, while the remaining 90% is stored digitally in banks, databases, and online transactions. This means computers and digital systems are the backbone of modern financial systems!
6. The First 1GB Hard Drive Was the Size of a Fridge
In 1980, IBM introduced the first 1GB hard drive. It was the size of a refrigerator, weighed over 500 pounds, and cost $40,000! Today, you can store terabytes of data on a tiny USB drive or cloud storage.
7. The QWERTY Keyboard Was Designed to Slow Typists Down
The QWERTY keyboard layout was actually designed in the 1870s to slow down typists using typewriters to prevent jamming of mechanical keys. Despite the invention of computers and digital keyboards, the QWERTY layout is still the most widely used today!
8. The World’s Fastest Supercomputer Can Perform Quintillions of Calculations Per Second
As of 2024, the world’s fastest supercomputer, Frontier, developed by Oak Ridge National Laboratory (USA), can perform 1.1 quintillion calculations per second (1.1 exaFLOPS). This is more powerful than millions of standard home computers combined!
9. The First-Ever Computer Programmer Was a Woman
Ada Lovelace, an English mathematician, is considered the first computer programmer. In the 1840s, she wrote the first algorithm intended for a machine, making her a pioneer of computer science before computers even existed!
10. A Computer Once Beat a World Chess Champion
In 1997, IBM’s Deep Blue supercomputer defeated world chess champion Garry Kasparov in a historic chess match. This was a major milestone in artificial intelligence and machine learning. Today, AI-based chess programs can easily defeat even the best human players.
11. A 5MB Hard Drive Once Required an Airplane to Transport
In 1956, IBM created the first-ever 5MB hard drive, called the IBM 305 RAMAC. It was the size of two refrigerators, weighed over 2,200 pounds, and had to be transported by an airplane! Today, you can store hundreds of gigabytes on a tiny SD card.
12. The Internet We Use Today Was Originally for Military Use
The foundation of the internet, called ARPANET, was created by the U.S. Department of Defense in the 1960s for military communication. It later evolved into what we now know as the World Wide Web, revolutionizing how we connect and share information.
13. More Than 500 Hours of Video Are Uploaded to YouTube Every Minute
Every minute, more than 500 hours of video content are uploaded to YouTube. That means 720,000 hours of content are added every day—more than anyone could ever watch in a lifetime!
14. The First Computer Bug Was a Real Bug
The term “computer bug” originated in 1947 when engineers found a real moth trapped inside a Harvard Mark II computer. The bug caused a malfunction, and from that moment, the term “debugging” became popular in the tech world.
15. The World’s First Smartphone Was Released in 1992
IBM introduced the first smartphone in 1992, called Simon Personal Communicator. It had a touchscreen, email functionality, and even apps! However, it was too expensive and large for mass adoption at the time.
16. Your Computer Can Detect Earthquakes
The BOINC (Berkeley Open Infrastructure for Network Computing) project allows home computers to contribute processing power to earthquake research. By analyzing seismic data, computers worldwide help scientists detect earthquakes and aftershocks faster than ever before.
17. The World’s Smallest Computer Is Smaller Than a Grain of Rice
IBM developed the world’s smallest computer, measuring just 0.3mm x 0.3mm, which is smaller than a grain of rice! It is designed for AI, blockchain security, and IoT devices.
18. The Password “123456” Is Still Used by Millions of People
Despite security warnings, “123456” remains one of the most commonly used passwords worldwide. Studies show that weak passwords are responsible for over 80% of data breaches, proving that people still underestimate cybersecurity risks.
19. Computers Can Store Data on DNA
Scientists have successfully stored digital data in DNA molecules, allowing enormous amounts of data to be stored in microscopic biological structures. DNA-based data storage could revolutionize future computing by offering nearly unlimited storage capacity.
20. Google’s First Office Was a Garage
Google, now one of the biggest tech companies in the world, started in a small garage in California. Founders Larry Page and Sergey Brin rented the garage in 1998 to run their search engine startup. Today, Google is worth trillions of dollars!
