The History of the Invented Computer: From Abacus to Personal Computers
The computer has become an essential part of our daily lives, with millions of people using it for various purposes. From simple addition and subtraction to advanced programming, the computer has come a long way since its inception. In this blog, we will explore the history of the invented computer, from the abacus to personal computers.
The Abacus: The Early Years
The abacus, also known as counting frame, is the oldest known device used for arithmetic calculations. It was invented by the Chinese around 200 BC. The abacus consists of a rectangular frame with rows of beads, which can be manipulated to represent numerical values. The abacus is still used in some parts of the world, especially in large calculations where speed and accuracy are essential.
The Antikythera Mechanism: An Ancient Wonder
The Antikythera Mechanism is an ancient Greek analog computer that was discovered in 1901 by divers. It is believed to have been used for astronomical predictions and can be considered as the earliest known example of a complex geared mechanism. The device has over 30 bronze gears and displays various astronomical information, such as the position and phases of the Moon.
The First Modern Computer: The Analytical Engine
The Analytical Engine is considered to be the first modern computer. It was designed by Charles Babbage, a British mathematician, and inventor, in the mid-19th century. The Analytical Engine had several interesting features, such as a punched card system and a memory capable of storing 1,000 numbers. Unfortunately, it was never fully completed due to funding constraints.
Electromechanical Computers: An Important Milestone
In the early part of the 20th century, electromechanical computers started to emerge. These machines used relays, switches, and other mechanical components to perform calculations. The first electromechanical calculator was invented by James Murray in 1893. However, the most significant breakthrough came in 1939 with the invention of the Atanasoff-Berry Computer. It was the first machine that used binary digits to perform calculations.
The Birth of the Personal Computer
The birth of the personal computer can be traced back to the 1970s. The first personal computer, the Altair 8800, was launched in 1975. It was an open-source platform that came in the form of a kit and needed assembly by the user. The 1980s saw the emergence of more user-friendly personal computers such as the IBM PC, which became the industry standard.
Conclusion
The history of the invented computer is a fascinating journey that has spanned several centuries. From the abacus to personal computers, mankind has come a long way in developing devices capable of performing complex calculations. As technology advances, we can only imagine what new and exciting innovations will emerge in the field of computing.
