What exactly "dual core proccessor is?

Answer 1

two proccessing cores in a single proccessor

Answer 2

I am a dell represenative. A Dual Core Processor Is A Part Of The System In Which Enables You To Do Multiple Things On Your Computer At Once. Like Listen To Music, Work On Microsoft Word, Be On The Internet And Watch Videos All At The Same Time. Computers That Do Not Have Dual Core Processors Can Also Multi-Task But Not As Fast And Not That Much Applications As A Dual Core Processor.

Answer 3

Two processors, not one.

In the classic computing environment, the computer work is shared by or multi-processed by a single chip. The list of task to do; moving the mouse, reacting to keyboard input, computing a spreadsheet, servicing a network transmission, etc. are done by a round robin sharing of the one processor. It splits the tasks and does a little of each, then the next, then the next, etc. As the clock speed of the processor increases, the execution of these many tasks becomes similtaneous to us. [Remember those days when the computer was 'too slow' and the mouse jumped or dragged, and the keyboard lagged?

Well, the dual core lets the work get shared among TWO processors. Twice as fast THEORETICALLY. I say that because some programs are not prepared to handle the double processor split of work and will still drag down one of the two. That said, a good operating system should realize this and redivide the load to the less busy processor.

Consider that this is not really a new concept. Supercomputers today, including those that cracked the human genome and that model nuclear explosions for the government, have been using parallel processing for years. I have seen it used for the last 20, at least. Most better graphic cards (display cards for the screen) use up to 8 procesors to do the calculations required for 3dimensional displays in games and simulations. Doing it in a commodity home PC CPU is fairly new tho.

HP and it's acquisitions of Digital Equipment and Compaq have some hefty computer systems that have done this for decades.

Answer 4

Dual core processor is a CPU with two separate cores on the same die each having its own cache. Simply its equivalent to "Two microprocessors in one".

In a dual core processor each core handles incoming data simultaneously and hence results in improved efficiency. While one is executing the other can be accessing the system bus or executing its own code. But both the cores share the same packaging and the same interface to the chipset/memory.

For utilizing this the Operating System should be capable to handle multi-threading.

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.

Dual core processors offers energy efficient performance.

Dual core sytems can be used in existing motherboards.

Keep in mind - its entirely different form HyperThreading.

Is it enough? ;-)

Answer 5

Dual-Core processor means presence of two cores on one die.
Whereas INTEL's new brand i.e. the Core 2 Duos , are two cores on different dies, according to my information. Core 2 Duos offer better performance than their dual-core counterparts with more threads per one clock cycle and reduced power consumption.

Answer 6

A dual-core CPU combines two independent processors and their respective caches and cache controllers onto a single silicon chip, or integrated circuit. IBM's POWER4 was the first microprocessor to incorporate 2-cores on a single die. Various dual-core CPUs are being developed by companies such as Motorola, Intel and AMD, and are scheduled to appear in consumer products in 2005. for more details...........click the link below

Answer 7

dual core refers to a processor having two processing cores. it's like a man with two brains/heads. can process two tasks at the same time, sort of deal.

Answer 8

Dual core technology refers to two individual microprocessors on a single die cast chip. This is essentially two computer processing units (CPUs) in one. The advantage of a dual core chip is that tasks can be carried out in parallel streams, decreasing processing time. This is referred to as thread-level parallelism (TLP).

Dual-core refers to a CPU that includes two complete execution cores per physical processor. It combines two processors and their caches and cache controllers onto a single integrated circuit (silicon chip). It is basically two processors, in most cases, residing reside side-by-side on the same die.
Dual-processor, Dual-core, and Multi-core: Keeping it straight
Dual-processor (DP) systems are those that contains two separate physical computer processors in the same chassis. In dual-processor systems, the two processors can either be located on the same motherboard or on separate boards. In a dual-core configuration, an integrated circuit (IC) contains two complete computer processors. Usually, the two identical processors are manufactured so they reside side-by-side on the same die, each with its own path to the system front-side bus. Multi-core is somewhat of an expansion to dual-core technology and allows for more than two separate processors.

Taking Advantage of Dual-core Technology
A dual-core processor has many advantages especially for those looking to boost their system's multitasking computing power. Dual-core processors provide two complete execution cores instead of one, each with an independent interface to the frontside bus. Since each core has its own cache, the operating system has sufficient resources to handle intensive tasks in parallel, which provides a noticeable improvement to multitasking.

Complete optimization for the dual-core processor requires both the operating system and applications running on the computer to support a technology called thread-level parallelism, or TLP. Thread-level parallelism is the part of the OS or application that runs multiple threads simultaneously, where threads refer to the part of a program that can execute independently of other parts.

Answer 9

Now why might you choose to over clock a computing device besides. (if it may be performed) no longer that it might make domicile windows run any speedier besides. (it won't) no longer something will make domicile windows run speedier. have you ever no longer worked that out already there is just one thank you to speed up your HP Compaq Presario CQ61-215TU computing device in case you haven't any longer heard the information at the instant Do what Hp are doing, they are dumping MS domicile windows and shifting over to their very own version of Linux, (WebOS) it quite is the comparable with Asus, Acer Sony, Lenovo Toshiba they are all shifting faraway from domicile windows to Linux

Answer 10

2 processors working at same time in a single processor
