How many core processors does my computer have? Does anyone have any ideas here? My teacher expects me to know this but I don`t have a clue.

"Has (central processing unit - or simply processor..."

For checking the number of cores your computer`s CPU has (central processing unit - or simply processor ), you can easily navigate through Control Panel, System information (or just right-click on My Computer and click on Properties) and a window will appear telling you the processor type and more details about your system.

Q. Is it possible to have two intel core i7 processors in one computer?
i want to build a computer. so can i have two intel core i7 processors in one computer. and if the answers is yes,what would be the difference between computer with only one i7 processor and computer with two i7 processors? will it be faster,would i be able to do more multitasking?

"However only server motherboards have dual slot cpus..."

yes you would, however only server motherboards have dual slot cpus, so if you wanted to do gaming, that is a nono because server motherboards arnt meant for gaming, you would do better with a normal mobo with 1 i7 for gaming. If its for pure multitasking however it will benefit you, heres a dual slot for the i7 xeon series http://www.canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=023131&cid=MBD.862

Q. What does dual core (in computer processors) actually mean?
whats the benefits and purpose of turion x2 or intel core 2 duo as opposed to a basic athlon or celaron m? surely it cant mean that there are two processors in one can it?

"A multi-processor system is faster than a system with a dual core processor..."

A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one. In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices. Accessing these slows down performance to the maximum speed the bus, RAM or storage device will allow, which is far slower than the speed of the CPU. The situation is compounded when multi-tasking. In this case the processor must switch back and forth between two or more sets of data streams and programs. CPU resources are depleted and performance suffers. In a dual core processor each core handles incoming data strings simultaneously to improve efficiency. Just as two heads are better than one, so are two hands. Now when one is executing the other can be accessing the system bus or executing its own code. Adding to this favorable scenario, both AMD and Intel's dual-core flagships are 64-bit. To utilize a dual core processor, the operating system must be able to recognize multi-threading and the software must have simultaneous multi-threading technology (SMT) written into its code. SMT enables parallel multi-threading wherein the cores are served multi-threaded instructions in parallel. Without SMT the software will only recognize one core. Adobe Photoshop is an example of SMT-aware software. SMT is also used with multi-processor systems common to servers. A dual core processor is different from a multi-processor system. In the latter there are two separate CPUs with their own resources. In the former, resources are shared and the cores reside on the same chip. A multi-processor system is faster than a system with a dual core processor, while a dual core system is faster than a single-core system, all else being equal. An attractive value of dual core processors is that they do not require a new motherboard, but can be used in existing boards that feature the correct socket. For the average user the difference in performance will be most noticeable in multi-tasking until more software is SMT aware. Servers running multiple dual core processors will see an appreciable increase in performance

Q. Can you run 2 dual core processors in one computer?
i was just wandering because someone approached me the other day and offered to sell me a computer which had 2 dual core so pretty much a quad core computer i was just asking on here if it was possible to run it like this or am i just someone asking to be ripped off

"Processor or an intel core 2 quad processor..."

are you sure they weren't trying to sell you an intel core 2 duo dual core processor or an intel core 2 quad processor ? You might be confused by the fact that intel uses two 2s in the branding of that processor. If you're asking if it's possible to run more than one processor in a computer (multiple chips) yes it is possible. This is generally only seen in servers, extreme work stations and super computers and isn't practical for pcs. Here's an example: http://www.youtube.com/watch?v=l8FUmS1h-5U super computers like this typically use multiple racks of motherboards to incorporate multiple cpus.

Q. If i have a dual core computer with the processors running 2.6 ghz does that mean the computer runs at 5.2ghz?
when you have a dual core do you add the speeds together to find out how fast the computer goes or do you just have two processors both running at 2.6?

"It is like having two 2.6 chips running at the same time..."

No.... the chip continues to run at 2.6 It is like having two 2.6 chips running at the same time . But the thruput is still 2.6 mhz

Q. Intel core 2 dual and centrino dual core processors: who has a computer with this type of processor?
is it noticeably better than the p4? do you understand how the dual processors work?

"Other significant reason would be now your machine would have 2 processors running simultaneously..."

I have an Intel Core 2 Duo in my iMac. It was a significant upgrade from G5, but I don't know about the Pentium 4. One of the most important reasons to upgrade would be Core 2 Duo is 64bit which is the future especially when all 32bit computers cannot compute the time (30yrs from now) The other significant reason would be now your machine would have 2 processors running simultaneously which gets work done faster. Other benefits would be lower processor temperatures, less energy consumption, and generally better performance.

Q. I got a quad core computer that presumably has 4 processors in it?
but it seems dead slow. what is supposed to be the advantage of 4 processors. it doesn't seem any faster?

"A multi-core processor does allow you to multi-task more..."

Quad cores are typically suited for video rendering and animation. MOst applications out there are only going to use two cores at most. A multi-core processor does allow you to multi-task more. But if you don't multi-task, there really isn't much benefit. In fact, I usually recommend the dual core over the quad core for most users (including high-end gamers!)

Q. How much does a dual core processor computer cost?
does anyone know how much one these would cost?? or a computer good enough to run black magic intensity pro??

"Most new computers are at least dual core..."

Most new computers are at least dual core, which cost about $300 give or take a but a decent one will cost about $600.

Q. What are computer single core processors?
what does single core mean

"Such as pentium 4 ht processors..."

Single core means the processor is open to one thread of data processing at once. Some processors have more than one thread and have one core, such as Pentium 4 HT processors, which adds the "virtual" effect of having a second core which is only emulated. Today these processors are generally old, or obsolete.
