If you are reading this, you probably at least know the basics of what a '''computer''' is. They were actually created in the 20th century.

The first personal computers appeared in 1980 or so.
The first personal computers appeared in 1974 or so.


In the 21st century, CPUs started being produced at over 1000 MHz, or 1 GHz in clock frequency. It appears that the maximum clock is around 3 or 4 GHz because faster CPUs would generate a dangerous amount of heat, so quad-core processors have been invented to get round this problem.
In the 21st century, CPUs started being produced at over 1000 MHz, or 1 GHz in clock frequency. It appears that the maximum clock is around 3 or 4 GHz because faster CPUs would generate a excessive quantity of heat due to the density of the transistor elements within and their individual power requirements, so multi-core processors with wide, high-speed intercommunication busses have been invented to get round this problem.
