How did someone come up with microchips?
457660
invented by a guy from texas instruments in the mid 1970's.\n\nThe first computer was made in the late 1600's. It was a big machine made from brass gears and valves and could perform mathematcal integration. Hardly worthy of UFO conspiracy theory\n\nThere hasn't been a fundamental change in computers for about 20 years, when the last logic gate was invented.\n\nAll changes have been in materials technology and manufacturing processes

PIC microcontrollers : low-cost computers-in-a-chip; they allow electronics designers and hobbyists add intelligence and functions that mimic big computers for almost any electronic product or project. The purpose of this book is not to make a microcontroller expert out of you, but to make you equal to those who had someone to go to for their answers. Book contains many practical examples, complete assembler instruction set, appendix on MPLAB program package and more...

I don't think anything has been invented that can't be hacked into. If you come up with that you will become a millionaire! There will always be thefts ... or someone trying.

Before the advent of the transistor. The telecommunication industry used gas filled diodes and triodes.Performing the basic function of electronic circuitry.So in order to design an average receiver or transmitter it needed many such diodes,triodes and other components like capacitors resistors to rig up the circuit which not only were very bulky but needed a high source of power. After the breakthrough in silicon technology transistors which were very small in size replaced these diodes and triodes and performed the same function with a fraction of the power used earlier. This not only enabled the equipment to become more compact but also made it mobile because of the low power consumption and the ease of carrying these equipment. This breakthrough in silicon technology eventually spurned a major rush in miniaturization of components and when the transistors got smaller and smaller scientists started building circuits on a single chip and this trend continued and presently millions of transistors can be packed in a single chip.Presently this miniaturization has reached such a stage that we are on the verge of what is being called nano technology. Miniaturization has greatly reduced the cost of components and thus the cost of the equipments

Charles Babbage was the first to conceptualize and design a fully programmable computer as early as 1820, but due to a combination of the limits of the technology of the time, limited finance, and an inability to resist tinkering with his design, the device was never actually constructed in his lifetime. A number of technologies that would later prove useful in computing, such as the punch card and the vacuum tube had appeared by the end of the 19th century, and large-scale automated data processing using punch cards was performed by tabulating machines designed by Hermann Hollerith.

The first integrated circuits were manufactured independently by two scientists: Jack Kilby of Texas Instruments filed a patent for a "Solid Circuit" made of germanium on February 6, 1959. Kilby received patents US3138743, US3138747, US3261081, and US3434015. Robert Noyce of Fairchild Semiconductor was awarded a patent for a more complex "unitary circuit" made of Silicon on April 25, 1961. (See the Chip that Jack built for more information.)

In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor. After the invention of integrated circuits revolutionized computer design, the only place to go was down -- in size that is. The Intel 4004 chip took the integrated circuit down one step further by placing all the parts that made a computer think (i.e. central processing unit, memory, input and output controls) on one small chip. Programming intelligence into inanimate objects had now become possible.

Let's look at an example:\n\nPeople needed to count so they invented numbers. Then they invented mathematics to study and use numbers. One of the use was making calculation. At some point they wanted to do this fasterr and they invented a machine to do it for them. But the machines weren't fast enough so they invented transistors and integrated circuits to make them faste. Then they realized that these machines could be used for communicating and they joined them in a network. Then some guys thought that there would be a nice thing if people could ask other people any question so they created Yahoo answers. So now at least two people (you and me) instead of (i don't know for you and working for me) are asking questions about how science and technology affects our lives (for you) and I am answering them (for me).\n\nAnd there are so many ways.... that a live wouldn't be enough for me to tell just a small part of them.

Here is a good article on what goes into making a chip and this goes for most memory as well.\n\nhttp://en.wikipedia.org/wiki/Integrated_circuit

which IC are you referring to? in general microcontrollers run code written in either C or assembly language, so you have to write the program, then compile it. after that you have to program it into the micro. that is done in several ways. some have to be plugged into a device that does it, some can be done through a serial port, and some use a JTAG interface to do it.

hey there, here's a link I found when i was searching like you as I'm also an electronic engineering student\nhttp://www.commlinx.com.au/microcontroller.htm\nthis link has a lot of simple projects... but the links below have my favorite projects, i didn't make any yet though\nhttp://www.bobblick.com/techref/projects/propclock/propclock.html\nhttp://www.luberth.com/analog.htm\nhave fun and good luck

In the old days computers were big and expensive. Many people would want to use them, eventually there were terminals attatched to the big computers so different people could use them at what seemed to be the same time. But then this guy bought a pc that was small and started using it at his desk. He figured out that he could connect his pc to the big computers in the same way big computers connect to each other. And then more and more people bought there own little, affordable, off-the-shelf computer and started connecting them. Now they are free to look for ring tones.

Nanotech is indeed real. Have you never seen surveillance cameras the size of a dime, and what about tracking devices about the size of a cigarette lighter?Do you remember how many different components use to be in a regular am radio & tv set? Tubes, capacitors, resistors, coils, etc. are now on a pc circuit board in the form of an integrated circuit about 1"x1/4". The first computer ever devised needed many rooms to house. The laptop now is less than the sise of some wire bound notebooks high school kids carry.
