Registers: Registers are the special sort of memory devices. They store the info that need to be processed and already processed by the processor.

Types of CPUs
CPUs are often divided in three major categories:

Transistor CPUs

Large Scale Integration CPUs
History
The term CPU was first utilized in industry within the early 1960's. Initially the term CPU was wont to define a tool for software execution and it came with the arrival of the stored program computer. a number of the important events associated with history of CPU are as follows:

Silicon, the essential component of processors, was discovered by Baron Jons Jackob in 1823.
In 1903, Tesla patented the electrical logic circuits (gates or switches).
In 1947, the primary transistor was invented by John Barden, Walter Brattain and Shockley at the Bell Laboratories.
In 1958, Robert Noyce and Jack Kilby developed the primary microcircuit .
On 15 November 1971, Intel introduced the primary microprocessor, the Intel 4004.
In March 1991, AMD introduced the AM386 microprocessor family.
On 22 March 1993, Intel released the Pentium processor, a 60 MHz processor with 3.1 million transistors.
On 4 January 2000, Intel released the Celeron 553 MHz bus processor.
On 22 April 2006, Intel released the Core 2 Duo processor E6320.
In November 2008, Intel released the primary Core i7 Desktop processors.
In January 2010, Intel released the primary Core i5 Mobile processors (i5-430M and i5-520E).
