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 are the advantages of using a microprocessor to control heating?
Advantages of Microprocessors is that these are general purpose electronic processing devices which can be programmed to execute a number of tasks. These are used in personal computers as well as a number of other embedded products. There are no disadvantages as such but when compared to fixed logic devices or certain ASICs (application specific intergrated circuits), there is a need to program Miicroprocessors and write software/firmware when used in embedded applications.
Sort array in ascending descending order?
#include<stdio.h>
#include<conio.h>
void main()
{
int a[10],i,n,j,t;
clrscr();
printf("enter size of array: ");
scanf("%d",&n);
printf(" enter array elements: ");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
printf(" array before sorting\n");
for(i=0;i<n;i++)
{
printf("%d\n",a[i]);
}
for(i=0;i<n;i++)
{
for(j=i+1;j<n;j++)
{
if(a[i]>a[j])
{
t=a[i];
a[i]=a[j];
a[j]=t;
}
}
}
printf("\n after sorting\n");
for(i=0;i<n;i++)
{
printf("%d\n",a[i]);
}
getch();
}
Is the Intel Pentium II an 8-bit processor?
No, it is a 32-bit processor in the sense of using 32-bit virtual addresses and having 32-bit general purpose registers and ALU that operates on those 32-bit GPRs. It does feature "MMX Technology", which can process 64-bits of information at a time by reusing the FPU's registers, however, in the more common usage, it is not considered a 64-bit processor due to the lack of 64-bit virtual address space and 64-bit GPRs.
What communicates directly with hardware?
The operating system of a computer is something that communicates directly with the hardware. This communication takes place through drive programs.
Yes.
Now do your assignment yourself like everyone else.
"CISC" stands for Complex Instruction Set Computer, CISC processor can execute complex instructions in one or more clock cycles. It is meant to differentiate it from a RISC or Reduced Instruction Set Computer, which can only perform one simple instruction in (usually) one clock cycle. A CISC is meant to have many machine level commands carried out as part of a single assembly command. The assembly command is broken into a series of "micro-code" commands which are executed internal to the processor by a "micro-code sequencer".
The term "download" means to receive data. If you download a file, then some outside source (another computer, an external hard drive, a CD, etc.) is transferring the data contained in a file to your computer or storage device.
There are a couple of different types of Intel processors, but I only know so much about this subject. But I do know that mac computers have Intel Core Duo processors and some HP computers have Intel premium 4 and Gateway has Intel Centrino Duo. If you want to buy the best Intel processor then buy a Mac since they come with the best Intel.
What processor will not work with a Socket 7 motherboard?
Many processors will not work on a Socket 7 motherboard. Providing a full list of every processor that is notcompatible with a Socket 7 board would be impossible.
How to Convert hex to bcd through an assembly program?
check this link for the code:

http://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/8-bit-HEX-to-BCD-convertor.html
A: The conversion is simple really a group of FOUR bits are usually the best method to simplify a BCD of four bits in hexadecimal. Example 1111 is just written F If it was written in octal the bits will be 3 as 111 or 7. As BCD becomes longer and longer these two methods were used to simplify the code a128 bits in BCD will be 8 zeros and ones or simply FF in octal notation it becomes 277
What do preoperative instructions include?
information about reserving blood products for surgery.taking or discontinuing medications before the surgery.eating and drinking before surgery.limiting activities before surgery.preparing items to bring to the hospital the day of surgery.
Will dual core processors be obsolete in the near future?
Technology is rapidly changing to anything is possible. Quad-core processors are next it will be sometime before quad-core processors become the market norm and dual core processors become obsolete.
when conditional jump instruction is executed it has 10 m/c cycles bt when nt executed it has 7 m/c cycles....while unconditional jump instruction has 10 m/c cycles...
Why CISC chips are relatively slow per instruction?
Short answer: CISC instructions consist of several RISC instructions. That makes CISC slower (per instruction) compared to RISC.
Compared to other architectures, CISC processors have relatively powerful instructions, which used run so called microprograms. For each instruction, the corresponding microprogram has to be fetched and executed, which is considerably slower than just using 'real' hardware instructions (compare RISC). According to wikipedia, microprogrammed processors are no longer common. Instead, a special unit resolves CISC instructions to RISC instructions.
Data encoder is a device or software program that converts information from one code or format into another. This may also perform several tasks related to entry, collection and dissemination of data.
Processor core frequency is measured in whAT?
Hertz is the measurement of cycles per second. The range that microprocessors use for personal computers are currently:
Megahertz
Gigahertz
How can you get a printer to print out what you want it to print out?
Power up printer, hook up usb or turn on wireless , go to Control Panel - Intstall new printer - seach for printerr- install lastest driver- accept default- print a test page- good to go.
Don't forget the paper and ink.
Why does the beep sound come when you switch on the CPU?
When the typical PC compatible computer is first turned on it runs through a series of self tests called the "Power On Self Test", or "POST" for short.
The original designers didn't know that there would always be a monitor or other kind of display device, so the standard was that the POST would sound a series ob "beeps" to identify the results of the POST.
A single, short "beep", generally means everything is okay.
note the link at the bottom of this page. It should guide you to a location that lists the POST "beep codes".
Which Intel and AMD processors support SMP?
The most popular entry level SMP systems use the x86 instruction set architecture and are based on Intel's Xeon, Pentium D, Core Duo & Core 2 Duo based processors and AMD's athlon64 X2, Quad FX or Opteron 200 & 2000 Series.
What is an alternative for a CPU?
There is no alternative for a CPU - Central Processing Unit. It's the brains of the computer. Without it, there's no control point on the motherboard.
