Computer History

.

Computer history is a vast and fascinating subject that covers the development and evolution of computers and computing technology over several decades. Here's a brief overview of some key milestones and developments in computer history:

• Pre-20th Century: The concept of mechanical calculation devices dates back to ancient times. In the 17th century, the French mathematician and philosopher Blaise Pascal developed the Pascaline, an early mechanical calculator. In the 19th century, Charles Babbage designed the Analytical Engine, which is considered a precursor to the modern computer.
• 1940s-1950s: The first electronic digital computers were developed during this period. Notable computers include:

ENIAC (1945): Often considered the first general-purpose electronic digital computer, it was used for scientific and military applications.

UNIVAC I (1951): The first commercially produced computer, it was used for business data processing.

EDVAC (1949) and Manchester Mark I (1948): Early stored-program computers that laid the foundation for modern computer architecture.
