The first semiconductor transistors during the late 1940s ended up followed by the silicon-dependent MOSFET (MOS transistor) and monolithic built-in circuit (IC) chip systems inside the late fifties, bringing about the microprocessor as well as the microcomputer revolution within the seventies. The pace, electricity and versatility of computers are already escalating substantially at any time since then, with transistor counts escalating in a rapid pace (as predicted by Moore's law), leading to the Digital Revolution through the late twentieth to early twenty first hundreds of years.
