History of computer 

The history of computers dates back to the 19th century when the first mechanical calculator was developed. However, the modern era of computing began in the mid-20th century with the development of the first electronic computers.

Here are some of the key milestones in the history of computers:

Mechanical calculators: The first mechanical calculator was developed by Charles Babbage in the 19th century, but it was never completed. Later, in the 1880s, Herman Hollerith developed a punch card system that was used to tabulate the 1890 U.S. census.

First electronic computers: The first electronic computers were developed during World War II, primarily to help with code-breaking and other military tasks. The most famous of these early computers was the ENIAC (Electronic Numerical Integrator and Computer), which was developed in the United States in 1945.

Transistors: In the 1950s, transistors began to replace vacuum tubes in computers, making them smaller, more reliable, and less expensive.

Integrated circuits: In the 1960s, integrated circuits were developed, which allowed for even more miniaturization of computer components.

Personal computers: In the 1970s and 1980s, personal computers began to be developed, with the most famous early examples being the Apple II and the IBM PC.

Internet: In the 1990s, the internet became widely available, revolutionizing the way people communicate and share information.

Mobile devices: In the 2000s and 2010s, mobile devices such as smartphones and tablets became increasingly popular, with many people using them as their primary computing devices.

Today, computers are an integral part of modern life, used in everything from business and education to entertainment and social media. The technology continues to advance at a rapid pace, with new innovations and breakthroughs being made every year.
