Microprocessors
A microprocessor is the heart of any computer, whether it is a server, a desktop machine, or a laptop. This single chip contains the arithmetic, control, and logic circuitry necessary to interpret and execute computer programs.

Can you use a French socket in Denmark?
There are two facets to this question: Can it be used safely, and can it be used legally. This applies to foreign fixtures in any country. This is a matter of the rating on the components. You cannot exceede the voltage capacity of the outlet or it will arc internally. The voltage of the circuit feeding the outlet must be the same as the voltage the outlet is designed for. You can use a 220V US NEMA outlet on European 220V safely, but you can't use a US 110V outlet. Also, the overcurrent device on the circuit must be less than or equal to the maximum current rating on the fixture. A 10A or 15A breaker is okay for a 110V 15A US outlet, a 20A breaker is not. If you respect the voltage rating and insure the current rating will not be exceeded, the fixture should be safe. This is another matter entirely. It is a matter of wether or not whatever regulating body that certified the outlet is recognized in your country. You will need to contact your local building inspector / code inforcement person to find out for sure. I wouldn't get my hopes up.
How does wattage of processor affect performance?
More wattage means more heat could be generated. Causing your cooling needs to be greater.
Comparing two processors by wattage, unless your trying to use less energy, should not play a factor in performance.
Is scientific calculator is an embedded system?
Yes, the scientific calculator is an example of an embedded system. In fact, an electronic calculator was one of the first applications of an embedded microcontroller. It is considered an embedded system because in addition to calculating answers, it is also handling low level functions such as input from the keypad and output to the LCD screen.
-------------------------------------------------------------------------------------------------------
Intel designed their first microprocessor (Intel 4004) for a Japanese calculator company called Busicom to replace a far more complex chipset that the company had designed themselves but was beyond Intel's ability to make at the time. Busicom did build the calculator as an embedded system based on the Intel 4004, but they eventually canceled the contract and gave Intel permission to sell the Intel 4004 to other companies.
Name three different types of microprocessor system application?
Industrial , Commerical and Domestic.
An FPU or floating point unit is the part of the microprocessor that does math.
What is the number of prcessing cycles that a microprossors can perform in a given second?
All depends on the processor. The processors specification should include a 'clock speed' which will be specified in multiples of Hz. 1 Hz = 1 cycle per second
How do you install a 240V electrical socket?
== == You need a 240 volt specific outlet and to run new cable to a new wall box fitted in the required position, etc. If it is a new circuit, the breaker box will require a new two pole breaker. But doing this is very, very dangerous. Done improperly, you could die, cause a house fire, or both. == == <><><> You will need to have room in your breaker box for a two pole breaker (i.e. a 20 amp type that spans both legs in your panel). You would then run 10 or 12 gauge cable from the box to the socket making sure to attach the cable according to the building standards in your area. If any of this sounds the least bit unfamiliar to you I would strongly recommend that you hire a professional to do this for you. Incorrectly wired circuits can cause serious injury and death as well as loss of property.
For your safety and that of anyone else who may to use the appliance, ask a professional licensed electrician to advise you or to do the work for you. If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized. : IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY

What is Difference between index register and stack pointer?
An index register contains an address that can be used during effective address generation, often along with an offset in the instruction or in another register. This is most useful when accessing elements of arrays or structures. A stack pointer is a specialized index register that points to a region of memory that can store temporary elements, in a last-in-first-out structure, such as return addresses, parameters, and local storage for function calls.
Ping is a special command line utility which allows to check accessibility of particular hosts. It uses ICMP protocol and because many online services block it, the utility not always provides correct results.
What is the function of registers in a micro controller?
Well , the register in micro processors or controllers is memory place that will save the values to be executed , for example if i want to add two numbers in 8085 i would first save ( or write ) the the first parameter into register "A" by applying this command "MVI A,80H" then i would write my second parameter into register "B" by applying "MVI B,20H" , now i can add ( sum ) them together bu using this command "ADD B" . the register "A" will have the result which is "A0".
As you can see to make any operation i should save ( or write) the values into register then i will execute command on them .
Good Luck !
Which direction do CPU fans point?
Tower monolithic coolers (the ones that mount the fan perpendicular to the CPU) are typically far more effective than flat-mount coolers that blow downwards at the CPU. However, to accomplish effective cooling, you'll need a separate case intake fan to draw in cold air from outside the case. These usually take the form of a case front-mounted intake fan and possible another side panel mounted intake fan. Lastly, you'll need a rear case mounted exhause fan.
Always mount tower cooler fans so they blow towards the rear exhaust fan, NOT towards the front of the case.
Is it possible to install Windows 2000 on a 64-bit CPU?
Yes, if installed on an AMD64 / EM64T compatible processor, Windows 2000 will not be able to take advantage of the additional addressing capabilities, however. There is also a 64-bit version of Windows 2000 available only for Itanium chips.
Does the computer's CPU carries out high speed calculations?
A CPU does not calculate anything. A CPU processes information 1s and 0s, on or off, binary code. What look likes calculations are really just a program response. When you open the calculator in any computer and you input 2*2, the person who programed that pice of software basicly sais when you insert 2*2 you should display 4. It does not go like when you insert 2*2 cacluate two times two. It is nothing like that.
When you click somewhere it is programed to react to the position you clicked it does not perform a caculation to figure out what you want.
What is name of component which holds the address of the next instruction to be executed?
program counter
What is assosciative mapped cache?
An associative cache is a cache that has 1 or more extra slots for each place in memory. So if two pieces of memory map to the same place in cache, you can write both entries. In this case, you will need a cache replacement policy to determine which gets evicted first when it's full and new data arrives.
