Generations of computer

Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.

The history of computer development is often referred to in reference to the different generations of computing devices. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. Read about each generation and the developments that led to the current devices that we use today.

The different generations are:

First Generation - 1940-1956: Vacuum Tubes
Second Generation - 1956-1963: Transistors
Third Generation - 1964-1971: Integrated Circuits
Fourth Generation - 1971-Present: Microprocessors
Fifth Generation - Present and Beyond: Artificial Intelligence
