Microprocessor is programmable single chip logic device that use to control any device or start or stop any device.
As we have describe the earlier about the WHAT IS THE MICROPROCESSOR ?
Revolution of Microprocessor being started with a bold and innovative approach after invention of Integrated Circuited. The First Microprocessor of the world was invented in 1971 name 4004 by Intel.
It is very interesting story, how the first microprocessor was designed. In 1969 Intel Corporation’s engineer “Ted Hoff” were working on designing a semiconductor memory. In 1969, Intel get a job to design a programmable calculator from a Japanese Company Bucsicom. But when the calculator is designed it original design have 12 different chip connected to each other to form that programmable calculator. So it have became big size then requirement. At that time Ted Hoff who was working in Intel (he was introduced 64-bit Semiconductor bipolar RAM chip) suggest about a general purpose single chip that can perform all the operations of that calculator and various logic functions, on the basics of 0s and 1s binary numbers provided to that single chip which is keep stored in registers, at the appropriate timing. Group of Register is use to store any number in binary number form.
And thus way Intel successfully designed that programmable calculator withe help of single general purpose chip, and some time latter Intel got a idea is that this general purpose single chip have a quality of processing data store in group of registers and performing the various logical operations. And keep this idea in the mind Intel became successful to designed 4-bit microprocessor 4004 in 1971.
Question- What do you mean by 4-bit microprocessor ?

And thus a way the improvement in the first designed microprocessor 4004 is started and Intel designed many advance versions of the processor likes……
| Processor | Year of Introduction |
| 4004 | 1971 |
| 4040 | mid-1971 |
| 8008 | 1972 |
| 8080 | 1976 |
| 8086 | 1978 |
| 8088 | 1979 |
| 80286 | 1982 |
| 80386 | 1985 |
| 80486 | 1989 |
| Pentium | 1993 |
| Pentium Pro | 1995 |
| Pentium II | 1997 |
| Pentium III | 1999 |
| Pentium 4 | 2000 |
It was not that only one company name Intel only designed the microprocessor. Motorola was the second company which also designed many microprocessors like…
Motorola 6800
Zilog Z80
