CPU

1) CPU
It is stand for central processing system; it is the brain of a computer. The CPU is built by gates. Mostly it refers as processor. It has a cycle to perform a full job. To properly perform its job, the processor has to complete a four steps cycle. The first step in this cycle is to fetch an instruction as of a software program's memory. After fetches the instruction, its second step is to decode the instruction.
During the execution step, the CPU completes the instruction. It accomplishes this by following the information gained during the decoding step. on one occasion the CPU has completed executing the instruction, the last step in this cycle is to write-back the results that occurred during the execution step. The CPU can write-back the results to its own internal register, or to the main memory of the computer.

2) when I update a CPU?
It is seemed much easy to update the CPU nevertheless you must know the CPU (processor) dose it much to the motherboard. The motherboard speed and the CPU must cooperate on passing signals. This are the main things before you consider to buy a CPU.

3) How do I monitor CPU temperature?
Too much heat damages electronics. Monitoring the temperature of CPU and other computer components keep them running appropriately. To properly use most soft ware of this type, you will need to ensure you have ACPI functionality enabled in your motherboard BIOS.

First Generation Monitoring Solutions:
Monitoring Temperature in System Bios
Numerous PC motherboards now contain hardware monitoring circuits those are capable to measure heat, voltages, and fan speeds. The majority of modern motherboards also allow you to configure alerts, alarms and actions to take based on specific temperature and fan settings.

Second Generation Monitoring Solutions:
The first generation of CPU (processor) temperature monitoring software packages purely gave the CPU temperature correct value. There is no alarms indication, events, or actions could be defined; it is very poor technology so the user must take of his or her system, to prevent the damages from the heat. If the user wasn't watching, the system could easily overheat and cause system damage.
The second generation sensor circuits have the ability to regulate and control environmental conditions automatically, so that second generation solutions are enough to keep the system stable when heat is an issue, and quiet when it isn't.

Third Generation Monitoring Solutions:
This is the newest technology software, it is directly interact with the mother board sensor and fan control system to control the heat according to the system environment condition. The mother board companies started to cover their customers and they like to give high performances from their mother board. So they are giving free software’s with their mother board.

4) What is Dual Core Technology?
The Dual core technology became with the idea of skipping on other and manages to do the both process at simulations time and the two processors are working in parallel. A dual core processor has two processors; they are combined as one processor non as Dual core Processors. It is efficient and very fast data execution. The dual core processor occupies less space on the mother board and it uses the less electricity. The core processors each has cache this two cache improved the multitasking ability of the system (computer).

5) How dual-core processors work
Dual-core processors work pretty much as you'd expect them to. At their most basic, both Intel and AMD have taken two mostly (or in the case of Intel, fully) functional processor cores and joined them together in a single processor die. Each core functions and processes data independently, and the two are co-coordinated by the operating system software.
