By Mario Lino And Mario Rodriguez. 4ºB/D

DEFINITIONCPU means central processing unit, also noun as the processor.This processes the information and instructions used by a computer. All the computer depends on its central processing unit to control its other parts.

ITS COMPONTENTSA popular range of processors is the pentium series produce by intel.The chip shown here is made up of over 27 millions tiny switchets, called transistors, mounted on a slice of silicon.

SPEEDThe speed with which a computer processesdata and instructions is measured in either megahertz or gigahertz. The microprocessors are becoming faster and faster, one gigahertz is igual to 1000000000 cycles/second.

CPUs WORKING NOWADAYS

Basically two manufacturers of microprocessors exist for the computer. On the one hand Intel is, and his range Pentium, and for other one, the AMD and his Athlon.

Also other manufacturers exist as IBM with the PowerPC and others much less known. They differ, for example, in size of the transistors, size of the memory or double core .Performance is very much major that the alone one).
