In the 1930s, electrical engineer Konrad Zuse built the Z1, considered to be the first programmable electro-mechanical computer. It utilized electromechanical relays for its operations, paving the way for the digital computers that followed.

Soon after, in 1944, Howard Aiken and his team at Harvard University developed the Mark I, one of the first fully electronic computers. The Mark I used vacuum tubes and punched cards, marking the transition from mechanical to electronic devices in computing.

Transistors and Integrated Circuits

In the 1950s, the invention of the transistor revolutionized computer hardware. Transistors replaced vacuum tubes, making computers smaller, faster, and more reliable. This advancement led to the development of the first generation of computers, such as the IBM 650 and the UNIVAC 1. These machines were still large and expensive, but they laid the groundwork for future advancements.

The real breakthrough came in the 1960s with the introduction of integrated circuits. Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor independently invented the integrated circuit, a small chip that combined multiple transistors, resistors, and capacitors on a single piece of semiconductor material. This development exponentially increased computing power and paved the way for the miniaturization of computers.

The Microcomputer Revolution

The 1970s witnessed the birth of the microcomputer, a small and affordable computer that could be used by individuals. The Altair 8800, introduced in 1975, is often considered the first commercially successful microcomputer kit. It inspired a wave of hobbyist and enthusiast communities, including the Homebrew Computer Club, where Steve Jobs and Steve Wozniak first showcased their creation, the Apple I.

2. From Personal Computers to Mobile Devices
