Do you know when the first computer was built? The point at which a computer was created is perhaps one of the most important events in the history of technology. This is because it radically changed human life. Now, we are going on a journey back in time to unveil the roots of this groundbreaking invention. When was the First Computer Invented?

The Early Beginnings (17th to 19th Century)

Blaise Pascal introduced the concept of a mechanical calculator in the 17th century. The Analytical Engine was invented by Charles Babbage. He was a visionary mathematician in the 1830s. Although it was never completed in his lifetime, it was the model of a programmable computer.

Pioneering Efforts (20th Century)

Computer technology underwent considerable advancements during the 20th century. In 1936, Alan Turing devised a theoretical machine known as the Turing Machine. This machine could carry out every computation which led the way for today’s computing.

The Mark I: Beginning of Electronic Computing (1940s)

In the early 1940s, the first programmable electronic computer in history was created at Harvard University. This electronic device was championed by Howard Aiken of Harvard University and his team. This greatly represented a turning point in the history of computing.

The Electronic Numerical Integrator and Computer (ENIAC) (1940s)

Soon after Mark I was ENIAC by J. Presper Eckert and John Mauchly at the University of Pennsylvania. This was the initial computer used for general purposes based on electronics. This also made an impact on military calculations during World War II.

Modern Computing Transistors and Integrated Circuits (1950s and 1960s)

The invention of transistors in the 1950s revolutionized computing. By replacing bulky vacuum tubes, transistors led to smaller and more efficient computers. The coming of integrated circuits in the 1960s downsized electronic parts even further. This advancement led to the creation of modern computing devices.

Personal Computers (1970s and 1980s)

The birth of personal computers happened in the 1970s. Innovators like Steve Jobs and Bill Gates contributed significantly to this invention. Consequently, the PC age started with the Apple I. Steve Wozniak and Steve Jobs released this groundbreaking computer in 1976. This milestone was followed by IBM’s first release of a PC in 1981.

The Internet Age (1990s and Beyond)

The arrival of the internet in the 1990s changed computing and communication. Tim Berners-Lee’s creation of the World Wide Web (WWW) transformed how people access and share information. This gave rise to the interconnected digital world in which we currently reside.

Frequently Asked Questions

Who invented the first computer?

A computer started as an idea, but Charles Babbage was the first person who thought up a mechanical computer. But the Mark I, made by Howard Aiken and his group was the first electronic computer that could be programmed.

Why was the first computer made? 

They were made for military and scientific purposes due to their ability to handle complex mathematical tasks. They also played a major role in codebreaking, ballistic calculations, and issues related to nuclear research.

How did the first computer work? 

The first computers like the Mark I and ENIAC used vacuum tubes and switches to do calculations. Programmers would key in instructions through punched cards or switches while the computer executed them accordingly.
