3. Microprocessors
A microprocessor is a tiny electronic chip found inside a computer's central processing unit and
other electronic devices. Its basic function is to take input, process it and then provide
appropriate output.
A microprocessor is a CPU on a single chip.
The microprocessor contains all, or most of, the central processing unit (CPU) functions and is
the "engine" that goes into motion when you turn your computer on.
A microprocessor is designed to perform arithmetic and logic operations operations include
adding, subtracting, comparing two numbers, and fetching numbers from one area to another.
4. Single Core
The single-core has only one processor mounted in a chip that is connected
to the motherboard.
• 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.
5. Dual Core
A dual-core processor has two microprocessors mounted in one single chip.
• In a dual core processor each core handles incoming data strings
simultaneously to improve efficiency.
• Just as two heads are better than one.
• Now when one is executing the other can be accessing the system bus or
executing its own code.
6. Benefits of Dual Core
Dual-core processors can be highly appreciated in heavy gaming or in
intensive data transfers using a single computer.
• For example, when you are downloading huge files and you are just using a
single-core, you would surely experience lagging of the data transfer.
However, dual-cores would not give you such scenario since the task is
divided.
• This makes your time to be used more wisely. It's like falling in line in a store
where there are two cashiers. You would surely pay your goods faster having
two cashiers than just having one.
7. Difference Between Dual Core & Core
2 Duo
Core2duo started before dual core.
• Core2duo is under the core2 brand, dual core is under the Pentium brand.
• Core2duo limits processor speed to 3.3 GHz, dual core limits it to 2.5 GHz.
• Core2duo offers cache size of up to 6MB L2 cache with scope for L3 cache
as well, dual core limits it to around 2 MB.
• Both are based on the core micro architecture.
• Core2duo comes for higher prices, and is simply better than dual core.
8. Difference Between Dual Core &
Multiprocessor
In dual core, resources are shared and the cores reside on the same chip.
• In multi-processor system, there are two separate CPUs with their own
resources.
• 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.
9. Quad Core
• Four microprocessors per chip.
• Intel says we can expect a 70 percent performance increase over the single
and double computing cores.
• Intel Launches Three New Quad-core Processors
11. The Motherboard
A motherboard is one of the most essential parts of a computer system. It holds
together many of the crucial components of a computer, including the central
processing unit (CPU), memory and connectors for input and output devices.
The most important part of a PC is the motherboard. It holds:
the processor chip
memory chips
chips that handle input/output (I/O)
the expansion slots for connecting peripherals
Some chips are soldered onto the motherboard(permanent), and some are
removable (so they can be upgraded).

13. Purpose of Motherboard
A motherboard provides the connection between all other computer parts.
Processors are attached directly to the motherboard, and the RAM, peripherals and
storage devices are attached as well.
Motherboards themselves, however, perform no computation and do not store
information
