5. Intel Corporation is an American multinational
semiconductor chip maker corporation headquartered
in Santa Clara, California.
Whereas, Advanced Micro Devices, Inc. or AMD is
also an American multinational semiconductor
company based in Sunnyvale, California, that develops
computer processors and related technologies for
commercial and consumer markets. Its main products
include microprocessors, motherboard chipsets,
embedded processors and graphics processors for
servers, workstations and personal computers, and
embedded systems applications.
7. As it refers, to the sensitive or we can say the central
main part of any system.
For eg:-
1.The core of the galaxy.
2.The core of the sun or the earth.
Here “CORE” refers to the part of a processor.
which is use to perform the opertion,
execution, etc.
8. INTRODUCTION
A dual core processor is a C.P.U. With two processors
or “execution cores” in the same integrated circuits.
Each processor has its own cache and controller, which
enables it to function or as efficiently as a single
processor .
However, because the two processors are linked
together, they can perform operations up to twice as
fast as a single processor can.
The INTEL CORE DUO, the AMD X2 and the DUAL
CORE POWER PC G5 are all examples of CPUs that
use dual-core technologies .
These CPUs each combine two processor cores on a
single silicon chip.
9. This is different than a “dual processor” configuration
in which two physically separate CPUs work together .
However, some high-end machines, such as the
POWER PC G5, QUAD use two separate dual core
processor together , providing up to four times the
performance of a single processor .
While dual-core system, has twice the processing
power of a single processor machine.
It does not always perform twice as fast.
This is because the software running on the machine
may not be able to take full advantage or both
processors.
10. In a dual core processor, each core handles incoming
data strings simultaneously to improve efficiency.
When one core is executing, the other can be accessing
the system bus or executing its own code.
A multiprocessor system is faster than a single core
system.
An attractive value of dual core processors is that they
do not require new motherboard but can be used in
existing boards that feature the correct sockets.
Multicore is similar to dual-core in that it is an
expansion to the dual core technology which allows for
more than two separate processors.
11. A CPU with two processors in the same integrated
circuit.
A dual core system is faster than a single core system.
They do not require new motherboard.
examples:
The intel core duo, the AMD X2, the dual core power PC
G5.
12. •Other types of multi- core processors also have been developed,
including quad-core processors with four cores each, hexa-
core processors with six, octa-core processors with eight and many-
core processors with an even larger number of cores.
14. WORKING
•The working of the traditional processors is relatively slow.
•This is because the set of instructions which we fed into the
system is executed and then stored in cache.
•The situation is difficult to handle when it comes to perform
multitasks and store it on the hard disk.
15. The data retrieval is far slower than the actual working of the
CPU.
The processor has to move forward and backward for
executing and storing set of instructions or programs.
Hence as a result the CPU works really slowly.
16. Mother board with microprocessors
Mother board with four microprocessors
17. Each processor is capable of handling the data stream
concurrently.
The working of the dual core takes place on the same
motherboard.
This means one does not have to install additional
motherboard to run two processors at a time.
18. REQUIREMENT
The dual core processor requires the OS to have a multi
threading capability along with software which contains
SMT (Simultaneous Multi Threading Technology)
technology written into its code.
It is important to use SMT software other wise the
system would not be able to make use of dual
processors.
19. One of the most common examples of simultaneous
multi threading software is Adobe Photoshop.
The multi processors are systems with two individual
central processing units while the dual core
processors share the resources are embedded on the
single chip.
20. However the performance of the dual core is better
than the single core processors.
Pentium D is the dual core
version of the preliminary
Pentium 4 processors.
21. How do Dual Core Processors
Work
The dual core processor differs from a single core in
that the single core processor must take the incoming
data bits one at a time, process that bit of data and
move on the next one.
A dual core process detects incoming data streams and
determines whether they could be calculated more
quickly if both cores were working.
22. The multi-processor system, because of the way the
data is split and reintegrated, can be significantly
faster than a dual-core setup.
23. POSITION
Motherboard (sometimes alternatively known as the
main board , system board, planar board or logic
board, or colloquially, a mobo) is a printed circuit board
(PCB) found in all modern computers which holds many of
the crucial components of the system, such as the central
processing unit (CPU) and memory, and provides
connectors for other peripherals.
Motherboard specifically refers to a PCB with expansion
capability - the board is the "mother" of all components
attached to it, which often include sound cards, video
cards, network cards, extra hard drives or other forms of
persistent storage, TV tuner cards, cards providing extra
USB or Fire wire slots, and a variety of thousands of other
kinds of custom components. (The term mainboard is
applied to devices with a single board and no additional
expansions or capability - in modern terms this would
include controlling boards in televisions, washing
machines and other embedded systems, which are not true
motherboards.)

processor

2. Female Processor.
