Computer and internet history dates back to the mid-20th century when the first electronic computers were developed. The first electronic computer, ENIAC, was developed in 1945 by John Mauchly and J. Presper Eckert at the University of Pennsylvania. It was a massive machine that weighed 30 tons and occupied a space of 1,800 square feet. ENIAC was used for military purposes during World War II.

In the 1950s, the first commercial computers were developed, and they were used for business and scientific purposes. IBM was one of the leading companies in the computer industry during this time.

In the 1960s, the concept of time-sharing was introduced, which allowed multiple users to access a computer simultaneously. This led to the development of the first operating system, which was called the Compatible Time-Sharing System (CTSS).

In the 1970s, the first personal computers were developed, and they were used for personal and business purposes. The first personal computer, the Altair 8800, was developed by Ed Roberts in 1975.

In the 1980s, the internet was developed, and it revolutionized the way people communicate and access information. The first email was sent in 1971, and the first website was created in 1991.

In the 1990s, the World Wide Web was developed, which made it easier for people to access information and communicate with each other. The first search engine, Archie, was developed in 1990, and the first web browser, Mosaic, was developed in 1993.

In the 2000s, social media platforms such as Facebook and Twitter were developed, which allowed people to connect with each other and share information. The rise of smartphones and mobile devices also changed the way people access the internet and communicate with each other.

Today, the internet has become an integral part of our daily lives, and it continues to evolve and change the way we live, work, and communicate.
