brain is supplied with parts that provide allow for input to it and allow it produce output for presentation to the one using it. Central Processing Unit The thinking part of the brain of the computer is the CPU or Central Processing Unit. This component provides all the control and manages calculations and manipulation of data. Computer manufacturers are always trying to squeeze more speed and multiprocessing capability (doing multiple things at the same time) out of it. This has led to the dual

RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell. The opposite of RAM is serial access memory (SAM). SAM stores data as a series of memory

Technology The most common description of the evolution of CMOS technology is known as Moore’s law. In 1963 Gordon Moore predicted that the transistor count would double every 18 months. The observation made by Gordon Moore was that the number of components on the most complex integrated circuit chip would double each year for the next 10 years. Frank Wanlass at Fairchild described the first CMOS logic gate (nMOS and pMOS) in 1963. Developments in complementary metal oxide semiconductor (CMOS) technology
