The Evolution of IT: 5 Surprising Facts About How Technology Changed the World

The world of information technology is changing so rapidly that we can barely keep up with new smartphone releases, cloud services, and autonomous AI agents. However, behind modern digital ecosystems lies a century of incredible experiments, bold engineering decisions, and accidental discoveries that changed the course of history forever.
Let’s take a look behind the scenes of the IT industry and recall five facts that might surprise you.
1. The First “Bug” in History Was an Actual Moth
Today, the word “bug” is a familiar term for any software error or technical glitch. But few people know that the term has a completely literal origin.
In 1947, pioneers of computer technology were working with an early electromechanical computer, the Harvard Mark II. The system unexpectedly malfunctioned. During diagnostics, engineers discovered a moth stuck inside a relay. Engineer and Rear Admiral Grace Hopper carefully removed the insect, taped it into the technical logbook, and wrote: “First actual case of bug being found.” Since then, this playful term has stuck firmly in the lexicon of programmers worldwide.
2. The First Hard Drive Weighed Nearly a Ton and Had 5 Megabytes of Memory
Imagine a modern storage drive with a capacity of several terabytes that easily fits on the tip of your finger. Now imagine the predecessor to modern SSDs — the IBM RAMAC 305 computer storage unit, released in 1956.
This “giant” could store a whopping 5 megabytes of data. The design consisted of 50 massive disks, each 24 inches in diameter, and the total system weight exceeded 900 kg. Transporting such a “disk” required a proper cargo truck. Today, an equivalent amount of data takes up less space than a single miniature icon on a smartphone screen.
3. The Legendary “Ctrl + Alt + Delete” Combination Was an Accidental Gift to the World
One of the most famous keyboard shortcuts in IT history, which has saved millions of users from “freezes” for decades, came about purely out of necessity. Its inventor, developer David Bradley, created this shortcut while working on the first IBM PC.
Initially, the combination was intended as a quick “secret” reboot exclusively for internal developer testing, to avoid waiting through a long cold-boot cycle every time. However, engineers and eventually users grew to love the feature, and it became a global standard for emergency control. Later, Bill Gates jokingly acknowledged the decision as a “design mistake,” noting that he wished the function could have been a single dedicated button.
4. Domain Names Used to Be Completely Free
It is hard to believe today, when the value of premium domain names reaches millions of dollars, but at the dawn of the internet, things were entirely different. In the early years of the World Wide Web, registering domains in the .com, .org, or .net zones was entirely free.
The situation changed only in 1995, when the commercial potential of the network became obvious, and Network Solutions introduced an official registration fee (around $100 for a two-year period). Those lucky enough to register short words or brand names back in the 1980s later became owners of true digital treasures.
5. Smartphone Power vs. Apollo Rockets
When humanity first landed on the Moon in 1969, the computing system of the Apollo 11 spacecraft was considered the pinnacle of engineering. Yet its processor had a clock speed of about 1 MHz and only a few kilobytes of RAM.
For comparison: today, an ordinary budget smartphone in your pocket surpasses the computing power of the Apollo mission by millions of dollars—or rather, millions of times. A basic mobile game, a background weather app, or a simple calculator uses more resources than NASA had at its disposal to conquer space half a century ago.
Technology develops exponentially, and what seemed like science fiction or a curiosity yesterday (like a moth in a relay or massive megaton disks) is today becoming the foundation for the era of cloud architectures, artificial intelligence, and next-generation cybersecurity.
