I don't know how many you want, but fuzzy logic has been used in computer vision, time series prediction, sensor fusion, a wide variety of mechanical control applications (cranes, automobiles, trains, etc.), image processing, signal processing, etc.

Here the concept is U'll decide the logic 1 nad 0 based on  spin of electrons...currently HP is working on it...if they come up with big result, it'll b a revolutionary change n da VLSI industry

You're going to have to look this up in your book or something, computers have thousands of uses, from simple email to playing movies to sorting files, etc. etc.

Very Large-Scale Integration \nVery-large-scale integration (VLSI) of systems of transistor-based circuits into integrated circuits on a single chip first occurred in the 1970s as part of the semiconductor and communication technologies that were being developed.\n\nThe first semiconductor chips held one transistor each. Subsequent advances added more and more transistors, and as a consequence more individual functions or systems were integrated over time. The microprocessor is a VLSI device.\n\nThe first "generation" of computers relied on vacuum tubes. Then came discrete semiconductor devices, followed by integrated circuits. The first Small-Scale Integration (SSI) ICs had small numbers of devices on a single chip – diodes, transistors, resistors and capacitors (no inductors though), making it possible to fabricate one or more logic gates on a single device. The fourth generation consisted of Large-Scale Integration (LSI), i.e. systems with at least a thousand logic gates. The natural successor to LSI was VLSI (many tens of thousands of gates on a single chip). Current technology has moved far past this mark and today's microprocessors have many millions of gates and hundreds of millions of individual transistors.\n\nAs of mid-2004, billion-transistor processors are not yet economically feasible for most uses, but they are achievable in laboratory settings, and they are clearly on the horizon as semiconductor fabrication moves from the current generation of 90 nanometer (90 nm) processes to the next 65 nm and 45 nm generations.

Its what you just added in your additional comment....it doesnt have common sense, but we do. Well, some of us do anyway =) \n\nComputers are a man-made machine and it only does things that the human programs it to do, but in a more efficient and faster way. If we train it to do mathematical things, it will solve it for us faster. If we want it to store huge amount of data, it will do it for us.\n\nHowever, they do not have common sense. We cant teach it to think morally or ethically. It just does what we tell it to do. They will never experience human emotions or concepts...it will only provide us the foundation and software to allow us to enter them into its system, but they will not process it like humans do.\n\nIts limitations is how much data we put into it. How much memory it has. Its life expectancy is how long the hardware survives. They get replaced easily because as the years passes, the technology and components get better. \n\nTheir limitations is how we built them.

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

I would suggest, if you can still find some, seven segment hexadecimal driver IC's.  They will convert discrete logic bits into the necessary outputs for a seven segment display.\n\nThe chip has unfortunately been discontinued and are a little fun to find now.  You can build up a substitute using logic gates or a FPGA (if you have access to those and the related equipment).\n\nThis site might be helpful...

I made an OR Gate for my 12th project. The external examiner loved it & gave me full marks.OR Gate is a simple device which is used in variuos appliances.\nOR gate\nThe output Q is true if input A OR input B is true (or both of them are true): Q = A OR B \nAn OR gate can have two or more inputs, its output is true if at least one input is true. \n\n  Input A Input B Output Q \n 0              0            0 \n 0              1            1 \n 1              0           1 \n 1              1           1 \n \n Truth Table \n\nTrust me.I'm giving u the right advise.For more information on GATES u can go to google.com\nAll the best

Each of these  transistors have their own unique uses. They are chosen for use according to the best operating characteristics of a particular circuit, not by random preference.

NAND gates are easy to build on the tiny scales required for high speed electronics.

A bistable multivibrator is a fancy word for a flip flop.\n\nSo there are several answers possible here. The easiest is to make the 4 transistors into two 2-input NOR or NAND gates and cross couple them (see below). Of course, that assumes by transistor you mean bipolar and not FET, but the ideas are the same either way.

That's a tall order.  If I had a spare 18 hrs I'd love to, however...\n\nThere's a chip that does it.  Its called an Arithmetic Logic Unit (ALU).  Here's some suggestions:\nhttp://www.xs4all.nl/~ganswijk/chipdir/f/alu.htm\n\nNo offense, but its a ton of work, with no assurance I'll get my 10 points.

TTL (Transistor-Transistor Logic) is a name for type of logic circuits which are constructed using the bipolar transistors. \n\nIn general the bipolar transistors such as the NPN and PNP transistors are current operated devices. In these types of transistors, when used for digital logic circuits, typically the input voltage is applied across the Base-Emitter junction. As a result of this a small base current is produced in that junction. This small base current is magnified by the transistor's current gain factor B(called Beta), resulting in a large amount of collector-emitter current. This is basiclly how a TTL switch works.\n\nThe TTL family of circuits are generally very fast, but this speed comes at the cost of higher power dissipation. Also, a typical TTL logic gate circuit requires multiple transistors and other passive components such as resistors. This results in lower number of gates that can be put on an IC built using TTL family.\n\nThe CMOS(Complimentary Metal Oxide Semiconductor) family of logic circuits are buit using Metal Oxide Semiconductor(MOS) Field Effect Transistors (FET). These types of transistors are voltage operated devices. A typical CMOS logic gate circuit can be constructed using as little as two MOSFET transistors (A CMOS Inverter) resulting in a much higher density of logic gates that can be put on an IC.\n\nAlso, CMOS gates use much much lower power to operate compared to the TTL gates because no resistors are required to build such circuits.\n\nCMOS logic also allows much higher operating voltages compared to the TTL family.\n\nOne drawback of CMOS family is that they are slower than the TTL family, however these days this may no longer be true.
