The first computers were developed in the mid-20th century, and they were quite different from the computers we use today. The first electronic computer, the Atanasoff-Berry Computer (ABC), was developed in 1937 by physicist John Atanasoff and graduate student Clifford Berry. However, it was not fully operational and was never completed.

The first fully functional electronic computer, the Electronic Numerical Integrator And Computer (ENIAC), was developed during World War II in 1945 by John Mauchly and J. Presper Eckert. ENIAC was a large, room-sized machine that used vacuum tubes to perform calculations. It was used primarily for military calculations, such as calculating missile trajectories and designing nuclear weapons.

In the decades since the development of ENIAC, computers have become smaller, more powerful, and more widely available. Today, computers are an integral part of our daily lives and are used for a wide range of tasks, from basic word processing and internet browsing to more complex tasks such as data analysis and scientific research.
