The best CPU right now is the Intel Core i7

• The Intel i7 has
• 3.06 GHz and 2.93 GHz core speeds
• Four processing threads
• 4 MB of Intel® Smart Cache
• Two channels of DDR3 1333 MHz memory

its munch, my program will add two 8-bit no. and store ina memory location

MVI 20H //copies 20h to accumulator

ADI 30H //adds 30h with the content of accumulator

STA 3000H //store result in 3000h lpcation

HLT //stop operation

this operation also can be done with taking the values from memory location as

LDA 2000H //loads accumulator with contents of 2000h location

MOV B,A //copies the content of accumulator to register B

LDA 2001H //loads acc with the content of 2001h

ADD B //adds acc with content of register B

STA 3000H //stores result in location 3000h

HLT //stops operation

and there are further many ways to perform the same dependent on many conditions such as carry etc.

Well, if your question is also "Why do we need registers?" then my answer would be that it quickens the mathamatical process of buying goods or services. If cashiers were good enough, and fast enough at math, there really wouldn't be a need.

Burst time is an assumption of how long a process requires the CPU between I/O waits.It can not be predicted exactly, before a process starts.

It means the amount of time a process uses the CPU for a single time. (A process can use the CPU several times before complete the job)

Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.

The two basic units of a CPU, or central processing unit, are the arithmetic logic unit and the control unit. The ALU basically performs operations while the CU takes instructions from memory and puts them into action.

RAM=Random Access Memory, used for fast swapping of data on computer

Processor= a small chip on the motherboard performing millions+calculations a second.

your computer uses ram all the time to keep background apps open, and to basically run everything.

your computer uses your processor when you do graphic intensive or calculation intensive things, such as gaming, video converting, multiple things at once, like running Photoshop, a video encoder, your internet browser, and watching a movie.

now if you want to know which to upgrade, it depends on the current status of your computer, and your aim of the upgrade.

It is important to double check the bottom of heat sink before attaching it to the CPU socket so as to ensure proper insulation. This one of the basic safety precautions in connecting a CPU.

Processor speed is one of those tricky things that's really hard to grasp. Most retailers and computer junkies will refer to a processor's speed by the processor's clock speed (in Hertz, Hz). This is usually an indicator on how fast the processor will work. Unfortunately, that's not always true.

For example, a single-core 2.16 GHz processor will not perform near as well as a dual-core 2 GHz processor. In general, newer processors that have many cores will throw clock speed ratings out the window. (For a more accurate definition of speed, try to find out how many "flops", or calculations per second, a processor can do. This is more commonly seen on supercomputers.)

Assuming that these are both single-core processors, a clock speed of 2.16 GHz would be faster than a clock speed of 2 GHz. If either of these are multi-core, however, it's probably better to go with more cores.

Triple

Edit:

"Triple?" What does this mean? Triple core? There are Rana processors that are shipped as dual-core but have 3 cores on the die. This means that your answer is wrong.

The most common examples are triple-core processors, but not all of them. As for actual examples, Phenom X2-X3 and Athlon X3 processors are famous for having locked cores.

Processor speed is benchmarked in terms of Hertz (Hz), or some derived unit of it (MHz = Megahertz, GHz = Gigahertz). It may also be measured in FLOPS, or Floating-Point Operations Per Seconds, or its derived units (MegaFLOPS, GigaFLOPS, TeraFLOPS, etc).

I would try running windows experience index if you have a PC.

If you would like to perform an action by energising to act ( Logic 1 = desired output) then it's positive logic.

If you would like to perform an action by de-energising to act ( Logic 0 = desired output) then it's negative logic.

Here is an example for the positive and negative logic

POSITIVE LOGIC NEGATIVE LOGIC

o/p Y = 1 (energise to act) o/p Y = 0 (de-energise to act)

A B Y A B Y

1 1 1 1 1 0

1 0 0 1 0 1

0 1 0 0 1 1

0 0 0 0 0 1

any how the required action can be performed by using either a positive logic or a negative logic.

so the transfer of heat from the cpu to the heatsink is 100% even. If not the imperfections in smoothness of the heatsink's surface doesn't allow for an efficient and even transfer of heat. This reduces the efficiency of the heatsink condiderably. But too much is not good either. Just enough to create a thin layer as direct heat transfer

Intel and Advanced Micro Devices (AMD)

The emitter of a transistor was placed a micrometer distance between two, so it was called a microprocessor. Technology advanced, and the distance was improved to nano meter. Still, they call it micro.

The "core" in a processor is the microprocessor inside of the CPU(Central Processing Unit).

For example, if you have a Dual Core CPU then you have 2 microprocessors inside of the CPU, this allows you to do two things at once, as a microprocessor can only do one thing at a time the only exception to this is Multi-Threading which allows one core to do the work of multiple cores, but its not as fast as having multiple cores.

The central processing unit (CPU) IS the brain of the computer.

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."
