How is a microprocessors speed measured?
Typically, microprocessors (like the ones found in computers), measure their speed in hertz. A hertz is the measurement of a cycle in a second. So, 10 hertz means 10 cycles per second.
In computing, a cycle (or, more specifically, a clock cycle) is the basic unit of measurement that the CPU uses to carry out instructions given to it by software. Therefore, in a CPU running at 900MHz, 900 million clock cycles will occur per second.
Software sends commands to the processor called, instructions. These commands are the basis for how all programs run on a computer and are handled by the computer in a very complicated manner.
However, a computer running at 3GHz, for example, is not performing 3 billion instructions per second. Some instructions take multiple cycles to complete and some can even have other instructions in the same cycle simultaneously.
To complicate matters further, it is not accurate to say that a higher speed processor is better than another one at a lower speed. Certain AMD processors, for example, run at lower speeds than comparable Intel processors of their family but, because they use different architecture, perform at the same (and, sometimes, higher) performance levels than CPU's with high clock speeds.
Also, processors with some sort of Hyper-Threading technology or, better yet, multiple cores (like Intel Core 2 Duo processors) will be rated at lowered speeds than other CPU's in their price range but, because of more than one (virtual) processor is running parallel to the others, more instructions are performed per clock cycle.
There are also a few more factors to consider but this is the gist of it.
Parts of the central processing unit?
The central processing unit (CPU) IS the brain of the computer.
Which processor is latest computer processor?
The latest trend in the processor technology is i3,i5,and i7 processors.these smart processors adapt to an individual's needs, automatically providing a 'boost' of performance for everyday applications. They become energy efficient to the point of shutting down processing cores or reducing power consumption to provide performance when people need it, and energy efficient when they don't."

they always get better and newer evry year
Intel Quad Core is one of the newer technologies developed by Intel for their consumer level Core 2 Quad and higher end Xeon processors. Basically, a quad core processor incorporates four processors onto one chip. In theory, you could see a massive improvement in performance from a quad core system but in reality, most programs, (and operating systems for that matter) do not yet support full utilization of all four cores.
How are microprocessors used in mobile phones?
Mobile telephones communicate with the mobile phone network using digital technology, yet the voice communication that still provides for the majority of mobile network traffic is purely analogue. A mobile phone must therefore convert voice communications into digital signals that can be transmitted over the network and it must convert digital signals received over the network into analogue voice data that can be heard by the mobile phone's user.
Who is the maker of AMD Athlon 64?
AMD is Advanced Micro Devices, Inc. located in Sunnyvale, California.
What are advantages and disadvantages of microcomputers?
Before the invention of the microcomputer, computer's were large, complex, and expensive, often occupying entire rooms. The microcomputer was much smaller, and could easily fit on a desktop. While they initially had limited processing power and memory, they were relatively cheap and become popular as home computers. From the 80's onwards, they became more and more powerful, but with the advent of the IBM Personal Computer and its compatibles, they became easier to maintain, highly upgradable and (gradually) more user-friendly -- making them ideal business machines as well as home computers. The term microcomputer isn't used very often these days -- it simply means small computer -- but it differentiates home and business computers from mainframes and supercomputers. Today, the need for desktop microcomputers is much less, however the term encapsulates laptops and other mobile devices which have begun to replace the desktop PC to a large extent.
The disadvantage of the microcomputer is the lack of processing power. While they are by no means under-powered for the tasks they were intended to fulfil, we still need mainframes and supercomputers for their superior transaction and mathematical processing abilities. So, ultimately, the only real disadvantage of a microcomputer is when it is used inappropriately.
What is the definition of CPU?
A CPU scheduler maximizes CPU utilization. It can do the scheduling based on two types, which is either a preemptive or a non-preemptive scheduling.
the famous for being ver great i7 is great. but any processor is fine. if you want to play games then you need a graphics card. a processor is for a hardcore internet user. but it wont matter if your using a really bad internet router
Can you replace a Intel atom precesser with a Intel atom dual core?
If it shares the same slot-type and the motherboard supports it, yes. In some cases, a motherboard will support a processor with a higher number of cores than was originally intended thanks to BIOS updates.
For instance, Asus M2N motherboards were originally released around the time that dual-core Athlons (Athlon X2) were gaining popularity. They supported single and multi-core processors of the AM2/AM2+ (slot) type by design. With the latest BIOS updates, they officially support AMD Phenom II X4 processors of the AM3 type up to the Phenom X4 945, and many users have had success installing 955s in these boards too.
If you are considering installing a dual-core processor in place of the existing single-core processor, it would be best to check the compatibility of your board with such processors before going further.
How many pins in Intel core i7?
There are four pins in an Intel Core i3. The Intel Core i3 is a desktop processor. The machine has a dual-core processing unit which runs two independent processor cores in one physical package at the same frequency.
Where does CPU go to get its data?
In a typical personal computer, the CPU is attached to the motherboard.
What is memory space in microprocessor?
memory space in microprocessor means cache ,it is the part of the microprocessor which contains the memory to store instructions which are used to perform different functions by the processor. where cache1 is referred to memory in microprocessor and cache2 is placed on motherboard which also contains memory to store instructions.
Memory space can also mean the total size of virtual memory that a CPU can address, and the layout (flat or segmented) of this space.
Most modern CPUs found in PCs (AMD and Intel x86_64 chips) are 64-bit CPUs, but, due to cost and practical use considerations, limit their virtual memory space to be 48-bits (or less).
Are Intel Core Duo Processors 64 bit?
No, but the core 2 duo processors are: http://www.intel.com/products/centrino/compare.htm I also found this web page intersting: http://www.answers.com/topic/intel-core-cpu
How can one compare the speed of two processors?
Use a benchmarking program.
Here is a list:
3DMark2001se
Most people don't use this program anymore because it's quite outdated, but if you really want the most benchmark utilities you can get then it would be a good program to get. Gamers benchmark. Mediumly recommended.
3DMark03
A program that a lot of people still use. Gamers benchmark. Highly recommended.
3DMark05
A program that only gives good scores if you have very up to date components. Still useful. Gamers benchmark. Mediumly recommended.
PCMark04
Fairly useful benchmarking utility. Mediumly recommended.
PCMark05
An updated PCMark. Mediumly recommended.
SiSoftware Sandra
Very useful benchmarking utility. Able to bench nearly all of you components separately. Highly recommended.
Super Pi
In case the name didn't give it away, this is a program that calculates 4,294,960,000 digits of pi. The benchmark comes in the form of a number (in seconds, perhaps minutes) that shows how long it took your computer to calculate those digits of pi. The simple score readout makes it very easy to compare scores. Highly recommended.
Aquamark3
An excellent gamers bechmark. Fun to watch (at least the first couple times) and very fun UI. Highly recommended.
What are the funtions of the f1 -f12 keys on a computer?
The F keys are function keys. They perform different functions in different programs. F1 is used as the "Help" key throughout Microsoft Windows and Office programs. F3 will start a search feature. In the old days (that would be the 1980's and 90's), the function keys would activate menus or other shortcuts. Some programs came with a cardboard template that surrounded the F keys to identify what function each key performed.
Can you run windows xp on Intel core 2 duo 2400 32bit?
Yes you can run Windows 32 bit on a Core 2 Duo CPU. But I would recommend you to go 64 bit instead as it is faster and can handle more memory, while 32 bit maxes out to 3.25 to 3.5GB of RAM. 64 bit can handle and use higher amounts of RAM and your PC will perform much better. I hope this answered your question.
Features of contemporary processors include a dual core and cache memory. They also have transistors for communicating information and instructions at the same time.
What five factors should be considered when selecting a CPU cooler or chill pad?
1 - CPU / Socket Type Compatibility. For example, Intel i7 Socket 1366. Choose a CPU cooler that is compatible with your socket type.
2 - Size. Compare the dimensions of the CPU cooler with the dimensions of your case to ensure it will fit. Heatsinks can be very tall, wide or both.
3 - Mounting Style. CPU Coolers usually have one of the following types of mounting styles.
A bolt through style requires the motherboard to be removed to allow a back plate for the heatsink to attach.
A clip style will usually use the stock retention module (a bracket around the CPU) or the retention module included with the CPU cooler.
A push pin style which is very similar to stock Intel coolers where four push pins are used to attach the cooler to the motherboard.
4 - Airflow. Ideally you will want a tower style CPU cooler that will allow single or dual 120mm fans to be mounted. A CFM rating in the 65 to 110 range is very good.
5 - Noise Level. Choose a CPU cooler that uses a 120X25mm fan. They are generally quieter and move more air compared to 92mm or 80mm fans. A dBA rating under 25 is considered to be very quiet.
Also don't forget case ventilation. If your case doesn't have a fan pulling cool air in the case and a fan pushing hot air out of the case, the CPU cooler will not be able to perform as expected.
Are AMD AM2 plus and AM2 socket processors compatible?
you will need to get pin count between your mobo and the processor you want to use
Ok thank you, both are 940 pin
AM2+ sockets are backwards compatible with both AM2 and AMD2+ processors. While AM2 sockets should be able to accept any AM2+ processor as well as AM2 CPUs, this usually is dependent on a BIOS upgrade of the system first, and many manufacturers have not provided such support.
your CPU genrates heat and reqires to be cooled if the cooler or the heatsink is removed from the CPU it will instantly stop responding and can cause physical damage
How you will handle the problem of the response time on your disk is slow?
Run a system cleaner to delete unuseful files like temporary files and run defragmentation. A GOOD free software for this is CCleaner, from Poliform. its free and it can scan all your rubbish files, and clean the registry which will make your computer faster.
