How do you determine the type of CPU in your system?
If I am answering your question correctly, to find out what CPU you are using, just go to 'My Computer' and on the left side of the window, there should be a tab that says 'About My Computer' or something like that. That is just XP, i dont know about Vista or Windows 7. If your on mac go to the apple and click about this mac and it will tell you what is in your system.

Is power supply a component of CPU?
CPUs get power from two places-- From the motherboard through the tiny pins on the bottom of the CPU (Which in turn gets power from the 20 / 24 pin connector that connects tot he power supply) and from a 4 / 8 (Only on the newest boards) - pin connector that directly feeds the CPU a very steady supply of power.
Both come from your actual Power Supply.

An encoder is a device used to change a signal (such as a bitstream) or data into a code. The code may serve any of a number of purposes such as compressing information for transmission or storage, encrypting or adding redundancies to the input code, or translating from one code to another. This is usually done by means of a programmed algorithm, especially if any part is digital, while most analog encoding is done with analog circuitry.
* A compressor is used to encode data into a smaller form.
* A multiplexer combines multiple inputs into one output.
* A rotary encoder is a sensor, transducer for converting rotary motion or position to a code of electronic pulses.
* A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal, which can then be decoded into position by a digital readout (DRO). Motion can be determined by change in position over time. Linear encoder technologies include capacitive, inductive, eddy current, magnetic, and optical. Optical technologies include shadow, self imaging and interferometric. Linear encoders are used in metrology instruments and high precision machining tools ranging from digital calipers to coordinate measuring machines.
In digital audio technology, an encoder is a program that converts an audio WAV file into an MP3 file, a highly-compressed sound file that preserves the quality of a CD recording. (The program that gets the sound selection from a CD and stores it as a WAV file on a hard drive is called a ripper.) An MP3 encoder compresses the WAV file so that it is about one-twelfth the size of the original digital sound file. The quality is maintained by an algorithm that optimizes for audio perception, losing data that will not contribute to perception. The program that plays the MP3 file is called a player. Some audio products provide all three programs together as a package.
In computer technology, encoding is the process of putting a sequence of characters into a special format for transmission or storage purposes.

Because the pins on the bottom of the processor can be easily bent (assuming that this is a processor for a PGA (Pin Grid Array) or SPGA (Staggerd PGA) socket. It is worth noting though that a processor for a LGA (Land Grid Array) socket is not as susceptible to this as the there are lands or pads on the bottom of the processor instead of pins; the pins are in the socket. The book that asks this question assumes PGA.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Very true BUT you can bend the lands in an LGA socket, rendering the socket hence the motherboard useless!
How does the 8087 coprocessor work?
the 8087 is a numeric data processor(NDP) it is basically made to work with 8086/8088 processors.it cannot fetch its instruction by own so its buses(address and data buses)are simply connected to the respective buses of the processor.its instruction are recognized by the word F because each and every instruction of this coprocessor starts with the word F.this is how the min processor distinguishes between its own and the coprocessor instructions.(eg):-FADD,FSUB,etc.this coprocessor has 8-registers eacch capable of storing 80-bit temporary real numbers. the BUSY pin of the coprocessor is connected to the main processor's TEST pin.this TEST pin is active low in nature.this is because the speed of operation of the coprocessor and the main processor is different. the need of this coprocessor is because the calculation speed of maths operations containing floating real numbers is very fast than the processors like 8086/8088.during the execution of the program if the processor encounters the instruction starting with F word(11011)then it simply gives control to the 8087.initially the coprocessor is initialized by loading it with the control word which gives the idea to the 8087 that which exceptions are to be ignored.usually after the calculations the status word of the coprocessor is loaded to see which errors hve occurred.
These values are incomparable.
GB = GigaByte = 1,073,741,824 Bytes
GHz = GigaHertz = 1,000,000,000 Hertz
GB is a measure of storage space, while GHz is a measure of frequency.
The speed of the CPU is determined by?
microprocessor's speed is determined by its clock rate. is normally determined by the frequency of an oscillator crystal . Typically a crystal oscillator produces a fixed sinusoidal waveform.
Cpu is made of an arithmetic and logic unit(alu) as well as control unit(cu).ALU performs all the arithmatic and logical functions whereas control unit holds the control that is decides the flow of control.Moreover, CPU contains various registers for storing information and data during processing
J. Presper Eckert and John William Mauchly, invented the EDVAC, perhaps the first computing machine with the "stored-program" architecture typical of modern CPUs.
That architecture is called the "von Neumann architecture" after John von Neumann, who write a widely distributed paper about the EDVAC.
Some people incorrectly believe that
Intel, as a company invented the first CPU.
While it is true that the people at Intel built the first microprocessor (a CPU on a single chip), the 4004, in 1971, which was a great achievement at the time,
there were a variety of other, previous CPUs built out of a few dozen integrated circuits, a few thousand individual transistors, or a few thousand vacuum tubes.
The first commercially available computer was the 1951 Ferranti Mark 1, designed by Freddie Williams and Tom Kilburn at the University of Manchester.
IBM sold about 20,000 of the refrigerator-sized IBM 1401 CPUs first introduced in 1959.

Interrupt Requests are method for handling requests from components such as Keyboard, Mouse, Clock etc & get attention of Processor.
Each specific components is assigned IRQ number.
Hertz is cycles per second, so 80,000 cycles per minute must be converted to cycles per second. This is accomplished, of course, by dividing 80,000 by 60, which results in 1333-1/3. So, this is a frequency of 1333-1/3 Hertz. As for its period, this is figured out by inverting the quantity. Frequency is expressed in cycles per second, as we already know, but the period is seconds per cycle. So, if the frequency is 1333-1/3 cycles per second, then the period is 1 second per 1333-1/3 cycles. So, divide 1 by 1333-1/3. This results in 0.00075 seconds, or to put it in more common terms, 3/4 of a millisecond.
I hope this helps. If you have any other questions, feel free to let me know.
What are two major components of a processor cooler assembly?
Temperature regulation of a processor is a very critical issue. Generally, the faster a CMOS (Complimentary Metal Oxide Semiconductor - a specific way of manufacturing transistors/chips) processor is clocked, the more power it draws. The more power it draws, the more waste heat it produces. The hotter the device gets, the higher the internal resistance, the more heat is produced (see the vicious cycle?)
There are several basic mechanisms for cooling a processor (or any chip for that matter):
(1) ambient air - the surface area of the chip touching both the room-temperature air combined with the heat being absorbed and distributed by the circuit board. This works well for low-power devices which aren't clocked especially quickly.
(2) radiated ambient air - this is basically a chunk of metal (usually aluminium) which absorbs the heat from the chip by direct contact and has a lot of surface area in which to dissipate the heat to the air. This is often used in conjunction with a fan.
(3) forced air - a fan either blows across the entire board, or is mounted directly to the chip.
(4) liquid cooling - here's where you get serious (and more costly) - a pump circulates a coolant over the chip and from the chip the heat picked up in the liquid is radiated out to the atmosphere. The basic components are the heat exchanger (radiator - usually a series of thin copper or aluminum plates), a pump, and the heat pick-up coil which sits on top of the chip.
(5) liquid cooling part two - instead of using a "normal" liquid to circulate, a compressed gas (such a nitrogen) is compressed into a liquid form and either sprayed or circulated over the offending part. This is typically only used for very, very high end experimental processors as it is pretty expensive to run continuously.
Differentiate between CU and ALU?
The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.
What is X86 family of processors?
x86 is a generic term referring to the "instruction set" of the most successful CPU "architecture". The architecture is defined as how the CPU arranges and uses resources such as RAM and I/O. Intel invented the x86 architecture, and AMD, VIA, Cyrix and others have manufactured chips compatible with x86.
CPU's read bytes from RAM as instructions and do stuff based on that data, this is how programming ultimately works. All computer languages eventually have to be translated into this data, called machine language. A byte is a number 0-255, and the set of byte values and their corresponding instructions forms the instruction set. There are many different types of CPUs that adhere to a specific philosophy, and therefore each major type of CPU has its own instruction set that is not compatible with a different CPU. Other types of instruction sets include MIPS, PPC, ARM, 6502, Z80, 68000, and others. The two main types of philosophies are CISC (Complex Instruction Set Computing) and RISC (Reduced Instruction Set Computing). CISC packs more "power" into each instruction but requires the CPU to be slower and more complicated, RISC makes each instruction do less but makes the CPU cheaper and faster. x86 is a CISC CPU (as were most in the late 70's/early 80's when x86 was born) with RISC extensions. x86 as a name comes from Intel's numerical designation various chips in the architecture. It begins with the 8086, and then 80286, 80386, 80486, and onward through the Pentium chips, Core line and beyond (often called "686" chips even though they no longer have numbers).
To summarize, x86 is a term referring to the way that the CPU in the common PC was built and how it functions.
How does the microprocessor work?
Suppose we give a 8-bit instruction ADD B to the microprocessor
then this instruction is not at all understood by microprocessor as it only accepts binary inputs
so first of all it stores the instruction in the INSTRUCTION REGISTOR
then it decodes this instruction ADD B to its suitable binary code 80H in the INSTRUCTION DECODER.. after converting to 80H then the microprocessor understands that ..
yes i have to add the content of the resistor B with that of A(accumulator) and store the result in the accumulator A
this is a small example how microprocessor operates facing the instructions
