The appearance of microprocessor allowed the fourth generation of computers to appear. This happed in 1971. At the moment we still have fourth generation computers. Microprocessor is a device that have thousand integrated circuits (millions of transistors) built in one silicon chip. The fourth generation was started by Intel 4004 chip that was developed in 1971. The greatest thing in computer evolution was that the whole computer that in first generation filled the whole room, now was integrated into a small chip.
4004 had all computer components integrated on one chip. This chip contained CPU, memory and input/output controls.
Ten years later (in 1981), IBM introduced the first computer that was dedicated to home user. Tree years later Apple introduced Macintosh. The era of mass usage of computers began. The use of microprocessors expanded and in our days, mostly all electronic devices use microprocessors or micro-controllers.
In the fourth generation the development of computer networks began. This lead to invention of the Internet. Many other great thing were developed during these years. Now it is very hard to imagine using computer without mouse, GUI or other features.
The fourth computer generation is a generation of computers as we know them now. Off course, during these years computers became more powerful, smaller, cheaper and so on. But the main idea is the same - microprocessor.
