Central Processing Unit (CPU)

The CPU is a microprocessor hardware to understand and execute a command from the software, call a processor (data processing). Microprocessor manufactured in the IC (Integrated Circuit), what is the IC which is a basic component consists of resistors, transistors and so on, the IC is also a component of the brain used as electronic devices. First time mid-20th century fabrication of semiconductor processor uses to show that this tool can perform functions such as the vacuum tube.

Integrating small transistors in large quantities to a small chip that is a huge increase for the assembly of vacuum tubes the size of a finger. Because of its small size is believed speed "switch" as well as electricity consumption is low, and can be produced in mass quantities. On the computer unit, the IC is the microprocessor used, we take one example of the Intel Pentium 4 has a resonance frequency of 1.8 trillion per second, Intel Pentium 4 in it contains 16 million transistors, not including other components, the manufacture of microprocessor fabrication is 60 nm . Just takes half a century later, the IC has been used everywhere, in computers, mobile phones and digital appliances lalinya, and is part of the trend of modern society. Skolar Many believe that the digital revolution brought about by integrated circuits is one of the important events in human history.
