🕰️ A Brief History of the Computer
🧮 The Abacus: The First Counting Tool
In ancient times, people used their fingers and stones to calculate. Later, the Chinese developed a bead-based calculating device called the abacus around 3,000 years ago. This device allowed for addition and subtraction.
⚙️ Mechanical Machines: The Devices of Pascal and Leibniz
In 1642, French scientist Blaise Pascal built the first mechanical calculator capable of addition and subtraction. In 1672, Leibniz designed a new machine that could also multiply and divide. However, these machines were not widely adopted.
🔢 Punch Cards: The Beginning of Data Storage
In 1890, Herman Hollerith developed cards that could store information. Holes were punched into the cards to encode data, and machines could read this information. This marked the emergence of the concept of “memory”!
🧠 The Father of the Computer: Charles Babbage
In the 1820s, Charles Babbage designed the first automatic calculating machine, which he called the Difference Engine. Later, he designed an even more advanced machine called the Analytical Engine. These designs laid the foundation for modern computers.
⚡ The First Real Computers: Mark-1 and Z3
In 1937, a massive computer named Mark-1 was built. Then in 1941, Konrad Zuse created the first programmable computer, the Z3. These computers were very large and slow but accomplished important tasks.
💣 ENIAC: The Beginning of the Modern Computer
In the late 1940s, the ENIAC computer was developed. It was enormous, filling an entire room, but it could perform calculations in seconds. For this reason, it is called the “first modern computer.”
🔬 Smaller and More Powerful Computers
After the 1950s, computers became smaller and faster. The invention of transistors and microchips allowed computers to enter homes.
🖱️ The First Computer Mouse and Personal Computers
In the 1970s, computers began to be used in homes. In 1981, the first portable computer was introduced. Later, components such as the mouse, screen, and keyboard were refined. Personal computers became available to everyone.
🌐 The Arrival of the Internet
In 1989, the internet entered our lives. Computers were no longer used only for calculations but also for communication, entertainment, education, and research. Even our phones became small computers!
