Microprocessor is a micro processor. \n\nIt processes data, performs calculations and  stores data in a memory. Everything that a computer does is overseen by the CPU and is therefore referred to as the "Brain".\n\nTwo good sites for more information is http://en.wikipedia.org/wiki/Microprocessor\nhttp://computer.howstuffworks.com/microprocessor.htm

Check out nanotechnology, the science and technology of building electronic circuits, devices, etc., from single atoms and molecules. \n\nThe science of construction in which dimensions of the components are less than 100 nanometers (nm; 10−9 of a metre), this is 100,000 times thinner than a human hair.\n\n The term was introduced by Nomo Taniguchi in 1974 to refer to mechanical machining methods. \n\nTop-down nanotechnology concentrates on manufacturing on this very small scale. Techniques such as photo lithography are used to make transistors for integrated circuits; the smaller the transistor, and the closer together they are packed, the higher the processing power of the chip. An Intel Pentium chip has about 1·5 million transistors. A specialized Dynamic Random Access (DRAM) chip carries 64 million transistors. \n\nBottom-up nanotechnology builds with individual atoms. \n\n\nThis area of new technology may hold the most promise on the horizon.

The following assumes you want to generate square and\ntriangle waves of relatively low frequencies:\n\nJust use a microcontroller. Use one output pin for the square\nwave and feed it through a D-type flip-flop configured as a \ndivide-by-two to get 50% duty cycle on the output. For the\ntriangle wave you can use PWM (Pulse Width Modulation)\nand hook the output pin to an RC (Resistor Capacitor) filter\nto form a simple D/A (Digital to Analog) converter.\n\nAlternatively, you can either buy a microcontroller with a\nbuilt-in D/A converter or add one externally. This will allow\ngeneration of any arbitrary waveform.\n\nA few of the many manufacturers of suitable microcontrollers\nare: \n\nAtmel, Microchip, Silicon Laboratories, and Texas Instruments.

The Intel 4004 \n\nIntel 4004 - The Chip \n\nThe 4004 was the world's first universal microprocessor. In the late 1960s, many scientists had discussed the possibility of a computer on a chip, but nearly everyone felt that integrated circuit technology was not yet ready to support such a chip. Intel's Ted Hoff felt differently; he was the first person to recognize that the new silicon-gated MOS technology might make a single-chip CPU (central processing unit) possible. \n\nHoff and the Intel team developed such an architecture with just over 2,300 transistors in an area of only 3 by 4 millimetres. With its 4-bit CPU, command register, decoder, decoding control, control monitoring of machine commands and interim register, the 4004 was one heck of a little invention. Today's 64-bit microprocessors are still based on similar designs, and the microprocessor is still the most complex mass-produced product ever with more than 5.5 million transistors performing hundreds of millions of calculations each second - numbers that are sure to be outdated fast. \n\nThe Pioneer 10 spacecraft used the 4004 microprocessor. It was launched on March 2, 1972 and was the first spacecraft and microprocessor to enter the Asteroid Belt.

A microcontroller is a small embedded computer chip. Today's microcontrollers are usually highly integrated, containing memory, clock generators, reset controllers, and I/O devices (like analog/digital converts and UARTs, for example).\n\nOne of the most popular available is the Microchip PIC. However, I like the Atmel AVR which is similar in price and power, but has excellent support for GNU C.

micro chips are used by satilites to find pets already! once they said cloning was not possible  but humans reached that yrs ago.... sex offenders, and high risk patients should be monitored, they have no legal rts.... but freedom will be at a  end w chip plantation.... also have u seen the latest gps global map systems?  i can see my subdivision and make of car on here at home  and took a look at my freinds house in the suburbs of boston!  he could not believe i told him he had a large pool in his back yard and a yellow garage w green roof.... eheheh...so what is next   we can spy on our own selves and freinds throughtout.... so will private owner s of these gps co. let the average computer joe find their own pet?  (good idea) stolen car,  or track our children's location when not at home?  or is hubby really at work?  what will happen to FREE WILL to do the rt thing?  what are ur thoughts?

It's like doritos for humans. A computer chip is a crunchy chip you feed your computer when it slows down.

You may be thinking of silicon doping. That is what they call it when very small amounts of very specific impurities are added to very pure silicon to make semiconductors, like diodes and transistors.

yes. diodes are essentially one way valves for electrons. a discreet diode (a single diode in a package) is created by "doping" a small piece of silicon- the dopant chemicals introduced into the silicon semi-conductor cause a migration of charges away from the center of the chip, positive (holes- actually a deficit of valence electrons)  to one end, and negative (excess valence electrons) to the other causing a depletion region in the center.

Radio Frequency Identification (RFID) cards contain tiny transceivers which are activated when the pass near a sensor.\n\nSome are self-powered (active), with a tiny built-in battery but most are "passive" cards, powered by an induced current from the sensor unit. Active cards have a much greater range and must be used whenever distance from the sensor is a factor. This generally is not an issue for proximity card applications.\n\nRFID chips can be read-only -- a simple fixed code is transmitted which identifies the card or product -- or read-write, where information contained on the card or tag can be modified.

It depends on what the microchip does, if its used in treating any illness or assists with any disabilities, eg: a implantable microprocessor that would aid the deaf in hearing, I am all for it. If its for vanity or biological enhancment or human tracking, no way. We are not canned products to be barcoded and categorised.

Did you ever stop to think, maybe it isn't microprocessors that are the next step in evolution, but plastics. Our brains are supposed to have 100 billion neurons. We could make a plastic structure with 100 billion interconections (cross-linked polymer molecules) a lot sooner than a chip with 100 billion transistors. So, be nice to plastics-- they might be throwing us out tomorrow.

infact the circuitry is so designed that the total power consumption is very small and thats the reason behind making such ICs using the nano technology. these days an IC may comprise millions of transistors allowing u to make the designs smaller and smaller. along with low cost

It is a custom chip that is not sold as a discrete component. As such the manufacturer does not need to release the pinouts, nor do they want to it seems.
