Blaise Pascal's Adding Machine: Invented in 1642, this machine was capable of adding and subtracting numbers.
Leibniz Adding Machine: Invented in the early 1700s, this machine could perform addition, subtraction, multiplication, and division.

19th Century: Mechanical Computing

Jacquard Loom (1800s): A weaving loom programmed using punched cards, which was key in inspiring the development of programmable computers.
Babbage's Difference Engine (1820s): Designed by Charles Babbage, this mechanical computer was intended to calculate and print mathematical tables.
Analytical Engine (1837): Also designed by Charles Babbage, this machine was considered the first general-purpose computer, though it was never built during his lifetime.

Early 20th Century: Towards Electronic Computing

Colossus (1943): The world's first electronic computer, built in England to help decode German messages during World War II. It was based on vacuum tubes.

1946: The Birth of Modern Computing

ENIAC (Electronic Numerical Integrator and Computer): Built by John Mauchly and J. Presper Eckert, ENIAC was the first general-purpose electronic digital computer.
Von Neumann Architecture: A computer architecture developed by John von Neumann, proposing the use of a single memory space for instructions and data.

1950s: The Transistor Era

The Transistor (1948): A semiconductor device that replaced vacuum tubes, leading to smaller, faster, and more reliable computers.
