Answer 2

Dual core technology, in it's more popular uses (Intel's Core2Duo processors and rival AMD's Athlon64x2 processors) is where a computer's CPU chip has essentially two separate processor cores and math co-processors fitted onto one chip using a single zif socket interface on the computer's motherboard. Several years back, if a user wanted to use two processors on the same system, a computer manufacturer such as Apple, Dell, IBM, Sun or Silicon Graphics would make a "workstation computer" or "file server" that had a motherboard with either two or four processor zif sockets, allowing for installation of multiple exact-same chips from Intel, AMD, or PowerPC to be installed on the same system. This setup on a "workstation" machine was frequently used for applications such as Corel Draw!, Adobe Photoshop, Illustrator, Auto-Cad, Pixar Renderman, Pro-comp Swivel 3D, Quark Express, Gimp, Seti Research in environments involving TV/Movie visual effects, military, Wall-Street, space exploration, university research, and product-development. These applications made special use of the availability of two or more processor chips on the same system, and the special versions of WindowsXP, MacOS, Linux, or Unix installed on these machines had software drivers designed to get the most performance out of these computers and their applications.
Nowadays though, AMD and Intel have developed ways of creating processors that incorporate two processors, but instead of requiring two motherboard zif sockets, the two processor cores are now housed in the same chip casing, making them both faster and cheaper. This has also allowed them make the multi-processor technology available to the masses. Now Dell, Apple, HP and others make even modest home computers with multi-processor horsepower, and for the most part, modern Linux, Unix, MacOS X, and WindowsVista take full advantage of AMD and Intel's dual core processors. This helps make multimedia, DVD movie editing, computer video games, slideshow, and photo-editing tasks faster and more stable. It has also allowed modern PC and Mac computers to utilize ever-greater amounts of hard disk space and motherboard RAM. The user of a dual core computer may also be able to run an even greater number of applications at the same time, with the computer experiencing little or no slow down. Even at present, both Intel and AMD through the major computer manufacturers also now offer "quad-core" processors that are being used in the highest-end servers, workstation and hard-core gamer machines, but these are very expensive at the present. Most average computers available now though have dual-core processors in them.

Answer 3

It means two processors working on one motherboard. This only makes it faster when there is more than one program going. So program one will be used by one processor and another program will be used by another program. If you are running just one program, the other processor won't kick in. If you are running three or more programs, then the others wait till the first two are finished needing the processors.

In the future, programs will be instructed to use multiple processors which can create more visually complex video games for example.

Answer 4

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.

Answer 5

Basicly having 2 CPU's in 1.

Answer 6

Its two prosessors in one unless you go with quad then its four in one.
