Does anyone know how a computer microchip works?

Well it stores its data as 1s and 0s. Thats all how a computer works. It runs all on 1s and 0s. If you hit the keyboard you might be telling it to type the letter "H" but it sees it as 11001111 (not really the right code). Its the same way a chip works. It sees everything it stores as 110011101010101011010101010.

check out this link, this is a company that makes the scanner chips. http://www.authentec.com/

Each chip has a crystal (oscillator) which has an exact frequency. Knowing the frequency people calculate how many executions it takes (from that frequency) to get one second. That is then calibrated (programmed) in the chip and … internal clock become live :)

I've only heard of this once before with a friend of mine that is deaf, has carpal's tunnel and a million other medical problems.  I believe the chip just simply sends out electrical pulses, mimicing the brain-transfer part of your nervous system.

Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor. The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.

Somone who knows alot about computers and how they work

No way.  Once that microchip is inserted, you'll have absolutely no privacy for the rest of your life.

Modern CPUs are made up of a collection of transistors, which basically act like switches, on an intergrated circuit (IC) chip. The equivalent of something like 42 million of them on a Pentium 4. It takes electricity to operate them. The processor connects to the rest of the computer's circuitry thru pins inserted into a socket on the motherboard. I know it's a simplified explanation, but I hope that's what you were looking for. There's an entry with much greater depth of info at Wikipedia http://en.wikipedia.org/wiki/Cpu

Machine code. The computers internal programming recognizes a connection from a keyboard via the ps2 connection or whatever you have(usb etc..). When you press a key on the keyboard a signal corresponding to that key is then sent to the computer and then is translated and then displayed on your monitor. Much like it is displaying every single character I am typing this very moment. Your computer receives and displays these signals almost instantly. Cool eh? :)

go to MS-dos and type "mem"\nu will be given all the details.

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.

CMOS - There is a small battery in your computer which acts as a watch. - similar to those small batteries we have on watches.

That's what makes a computer (silicon computer chips)\n\nit's called "silicon" computer chip not because it's silicon but because the semi-conductors (transisters) are planted in silicon (it's just the way they build them now to make them so small)\n\nEvery computer including the one you're on, Xbox, Printers, your cellphone, even calculators, etc... anything that is computerized has that chip in it.\n\nIn your computer you can find it on the mother board, it looks like that...\nhttp://www.enviroliteracy.org/images/page-spec//silicon-chip.jpg\n---it's about the right size too.\n\nThey are used to process the information, it's like your brain. It's the brain of the computer,it tells everything what to do, that's what makes everything work!\n\nWithout them, the computers will be huge (like a city block huge) Just like the ones people first built (with a bunch of wires and crap)\n\nAt the link below, you can see various silicon computer chips...\nhttp://images.search.yahoo.com/search/images?p=silicon+computer+chip&sm=Yahoo%21+Search&fr=FP-tab-img-t&toggle=1&cop=&ei=UTF-8\n\n\n\n\nAnd just a little extra for your school project...\nThis is how they make those silicone computer chips...\nI have a friend that works there, he got me one of the unfinished products (it's a shiny disk that's about the size of a waffle) It has like 100 of them on there and they cut them out with a microscopic water stream!!!...\n\nhttp://radio.weblogs.com/0105910/images/3dchip.jpg\n\nhttp://www.intel.com/education/makingchips/index.htm\n\n\n\n\n\n\n\nCheers!!!\n\n\n\n\n\n\n\n\n.
