You know this topic is too extensive to cover here. \n\nThere is some good reference material covering both types of processors here: http://ourworld.compuserve.com/homepages/r_harvey/doc_cpu.htm \n\nIn Pentium class processors, there also model-specific registers  http://ourworld.compuserve.com/homepages/r_harvey/doc_cpu.htm

As you probably know the registers are of 16 bit width in 8086.All definitions are based on that width.\n\nOverflow Flag (OF) - set if the result is too large positive number, or is too small negative number to fit into destination operand:- This means that it cannot fit into the required bit-width, hence literally overflows out.\nthe flag is set for such situations.\n\nOverflow Flag (OF) - set to 1 when there is a signed overflow. For example, when you add bytes 100 + 50 (result is not in range -128...127). during unsigned operations , this has no meaning. even if it's set it's not to be considered.\n\n\n\nCarry Flag (CF) - set if there was a carry from or borrow to the most significant bit during last result calculation.\n( this is used in add/sub operations)\nalternative but better definition:-\nCarry Flag (CF) - this flag is set to 1 when there is an unsigned overflow. For example when you add bytes 255 + 1 (result is not in range 0...255). When there is no overflow this flag is set to 0.\n\n\nAlso the field address in the status register varies. check out\nhttp://www.emu8086.com/assembly_language_tutorial_assembler_reference/flags.gif\nfor the exact locations

Well x64 is a 64 bit architecture and x86 is a 16bit, 32bit and 64bit architecture. There are such things as x86-64bit Processors. But the x86 is based off a naming convention used for old processors such as the 8086, 286, 386, 486 and the Pentiums were also known as 586. \n\nThe x86 architecture has been around since the late 70's and pretty much every processor now days even the x64 is based on it. \n\nSo an x86 when you see that you can think 32bit and the x64 you can assume 64 bit. The major difference is how big the word size is and how much memory it can address at a given time. \n\n32bit tops out approx at 4GB the 64bit tops out into the you will never use this much memory on todays market. \n\nI provided a link that has more details then I could provide in the Yahoo Answers.\n\nCheers!

most likely that you have a computer with a Genuine Intel processor\n\nx86 refers to the intel 80286 processor family that is used in the PC. The other CPU manufacturer is AMD.\n\ni leave a table with cpu speed

8085 has an 8-bit architecture and the index register is 16 bits.  3 2-cycle ops: First increment lobyte, then carry, then increment hibyte.

HEX is a type of numbers for human to read computer numbers.\n\nThe very old old CPU in 90s is using 8 bit registers. (Now we are using 32 bits, Intel also have some 64 bits. I guess the next generation CPU will be 128-bit)  It has 4 bit in front, and 4 bit in the back of the register.  4 bit (binary, 4 digits, ex 1101) can be 15 at max (1111 binary= 15 in decimal number), that means, if a number is 16, then it needs go to another CPU register(1 0000 binary = 16 decimal). it is so hard and confused for us to read and do the caculation.  so we create Hex number. \nHex #s are: 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E,  and F. (A=10, B=11... F=15, note that F+1=10, 10 in Hex equals to 16 in decimal number). With HEX, it is much eaiser for us to do the caculation that CPU does.\n\n\nASCII = American Standard Code for Information Interchange. The ASCII are the keys and characters on your keyboard. Computer doesn't know what is A, B or C. It knows only number.  Every time you type a letter with your keybord, your keybord sends a number to the CPU, and the CPU convert it to a letter. For example, when you type the letter "A", the keyword sends the number "65" to the CPU, and the CPU will use the ASCII table to find out what letter 65 stands for and display it. (note 65 in decimal number in the ASCII is A, 66 is B, 67 is C, and so on)\n\nThere a lot of other machine characters that you can't type with your keyboard. But you can copy it from a non-ascii file. For example, .exe file, MS Excel file (Open these .exe and Excel file with Windows Notepad, you will see those charcters).

Lots of stuff in the other answer, but I'd still like\nto offer a few words.\n\nCurrent mainstream processors (ie. for laptops,desktops,\nand servers) are either of the 32-bit variety (ie. Pentium)\nor 64-bit (Opteron, Power, UltraSPARC, HP-PA, Itanium, \nand Pentiums of the "EM64T" variety).  Generally speaking,\nthe 64-bit processors have the option of either running\nolder, 32-bit software (effectively pretending to be\nthe older 32-bit processors) or running newer 64-bit\nsoftware.\n\nSo, for example, if you purchase a 64-bit Opteron\nbased system, you have the choice of running a 32-bit\nversion of Windows on it or of getting an updated version\ncapable of taking advantage of 64-bit operations.\nNote that a 32-bit OS can only run 32-bit applications;\nhowever, usually a 64-bit OS can run both 32-bit and\n64-bit applications.\n\nFor most situations, it doesn't matter.  Most of the\nsoftware that most people use runs just fine in 32-bit.\nThe catch comes if your application needs a *lot* of\nmemory -- exceeding 4GB.  In that case, you'll want\na 64-bit version.  But note that to run it, you'll \nneed a 64-bit OS.  \n\nThat is the criteria most often used to decide if \nyou need to upgrade from a 32-bit to 64-bit OS.

Those numbers represent how fast they are compared to a Pentium 4 processor.  First a little explanation is in order, AMD 64 and Athlon processors have more L1/L2 cache than comparable Pentium 4 processors in some cases but all AMD processors have faster data pathways and can process information more efficiently than a Pentium 4 processor.  So when for example when you see an AMD 64 4000+ running at 2.4GHz that does not mean a single thing as far as clock speed goes.  Intel is famous for milking the clock speed which is no longer the determinant when it comes to the performance of a processor.  Back to the AMD designations, the 4000+ (or any XXXX+) designation tells you that in this case with 4000+ it performs to the equivalent of a Pentium 4 running at 4GHz which Intel has been unable to produce, they top out at 3.8GHz.  So a 2700+ is the equivalent of a Pentium 4 at 2.7GHz, 3200+ is the equivalent of a Pentium 4 at 3.2GHz and so on.\n\nBut note that the lower end Sempron has the same designations of XXXX+ like a Sempron 3000+ but it is not being compared to a Pentium 4.  The Sempron 3000+ means it performs like an Intel Celeron clock at 3.0GHz.\n\nSo when you see the "+" designation on an Athlon it is being compared to a Pentium 4 and the "+" designation on a Sempron is being compared to a Celeron.\n\nIf you want a further explanation of why AMD processors can get by with slower clock speeds and still operate faster than Intel offerings, see these benchmarks over at Toms Hardware and note how all the AMD Athlon chips are at the top of the chart, http://www.tomshardware.com/2005/11/21/the_mother_of_all_cpu_charts_2005/page24.html

Nothing really. They have the exact same capacity. DDR2 has higher clock speeds, for a price, of course. But if you compare let's say DDR PC 2700 to DDR2 PC 2700 there is absolutely no performance difference. Also, DDR and DDR2 are not compatible with one another.\n\nI just wanted to edit my answer to address the idiot below me; The "Geek Squad Agent" I hate people like you that type out verbatim answers from your latest PC World magazine. Why not use actual experience, and give real answers. Anyone can just look crap up in a book. They come here for REAL answers from REAL People.

The Pentium is a fifth-generation x86 architecture microprocessor by Intel. First shipped on March 22, 1993, it is the successor to the 486 line. The Pentium was originally to be named 80586 or i586, but due to an ongoing battle with Advanced Micro Devices over the use of the previous processor generations' names--80386 and 80486--and the inability to trademark a number, Intel enlisted the help of Lexicon Branding in order to give their new processor line the Pentium brand. i586 is used in programming reference and parlance though, referring to all the early Pentium processors, and processors that are feature-compatible with the Pentium made by Intel's competitors.

Probably nothing but a die shrink. The "A" is the newer one, and the non "A" is going to be obsolete. You should be able to use the same programmer. For more info go to www.microchip.com

both are proccesor one for laptop and other for pc.INTEL PENTIUM is more reliable.problem with AMD is heating and intel support grater graphics properties but sound support for AMD is grater.
