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.

What is the difference between register addressing mode and register indirect addressing mode?
Ans: In the register addressing mode the operands are in registers which reside within the CPU. Register-mode instructions are 1-byte instructions and can be executed within the CPU without the need to reference memory for operands.
But in the Register-indirect addressing mode the instruction specifies a register or a pair of registers in the processor whose contains give the address of the operand in memory. This mode uses 1-byte instructions even though the operand is in memory. Before using a register-indirect mode instruction, the programmer must ensure that the address of the operand is placed in the processor register with a previous transfer-type instruction. A reference to the register is then equivalent to specifying a memory address.
The consideration that would be of the greatest importance when building a workstation that will run multiple virtual machines would be the number of CPU cores. The other would be the amount of RAM.
What do you do when mIRC is giving you the error unable to create socket?
The best thing you can do when mIRC is giving you an error that it is unable to create a socket is to check your firewall settings. Another solution is to change the server as the current one may be offline.
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 !
