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.

The power supply could be going bad - it's a 160watt PS, and that's quite low.
I just replaced the old one with a 250 watt PS and it's humming away.
The orange light in the front is a good indicator that either the floppy or the other drives may not be connected properly.
What are the latest additions to MRI technology?
The latest additions to MRI technology are magnetic resonance angiography (MRA) and magnetic resonance spectroscopy (MRS).
What is the function of a stack pointer?
Stack pointer points to the topmost / most recently referenced location on the stack;
- Nutan
What is the major difference between TV and CPU?
There are lots of "major differences", as they are totally dissimilar devices with different purposes. For one, televisions are typically very large, as they must have a screen large enough to be viewable. CPUs and other microprocessors are much smaller, usually under two inches across.
Is a Intel celeron dual core processor fast enough for basic home use?
Yes. This does depend on what you call ´basic home use´.
How do you connect laptop to CPU without network?
Assuming that by CPU you are referring to a separate desktop machine, you can use a crossover ethernet cable to connect them directly
What is the first CPU to include an internal math co processor?
Not sure if it's the first but:
"Intel processors later than the 80486 integrated floating-point hardware on the main processor chip" source: http://en.wikipedia.org/wiki/Coprocessor#Modern_PC_coprocessors
Couldn't find anything about Motorola processors with math coprocessors built-in.
I believe AMD was just behind Intel with the processor design.
John Vincent Atanasoff developed the ABC (Atanasoff-Berry Computer) at Iowa State University in October 1939 as in the following link.
Patent dispute details: J. Presper Eckert and John Mauchly were the first to patent a digital computing device, the ENIAC. The ABC had been examined by John Mauchly in June 1941, and Isaac Auerbach,[6] a former student of Mauchly's, alleged that it influenced his later work on ENIAC, although Mauchly denied this (Shurkin, pg. 280-299). In 1967 Honeywell sued Sperry Rand in an attempt to break their ENIAC patents, arguing the ABC constituted prior art. The United States District Court for the District of Minnesota released its judgement on October 19, 1973, finding in Honeywell v. Sperry Rand that the ENIAC patent was a derivative of John Atanasoff's invention. The decision was not appealed.
Campbell-Kelly and Aspray conclude:
The extent to which Mauchly drew on Atanasoff's ideas remains unknown, and the evidence is massive and conflicting. The ABC was quite modest technology, and it was not fully implemented. At the very least we can infer that Mauchly saw the potential significance of the ABC and that this may have led him to propose a similar, electronic solution.
The case was legally resolved on October 19, 1973 when U.S. District Judge Earl R. Larson held the ENIAC patent invalid, ruling that the ENIAC derived many basic ideas from the Atanasoff-Berry Computer. Judge Larson explicitly stated, "Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr. John Vincent Atanasoff".
What does F stands for in PIC12F629?
- their older PICs that stored the program in EEPROM used a "C" in that field of the partnumber
- the new PICs that store the program in FLASH use an "F" in that field of the partnumber
They probably have other letters they will use for other types of program memory that they might use (e.g. masked programmed ROM) but I couldn't find any others than "C" and "F".
Splitting a single processor into multiple virtual machines is called what?
hardware - based virtualization
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.
