Microprocessors

The acronym AVR has been reported to stand for Advanced Virtual RISC, but it has also been rumored to stand for the initials chip's designers: Alf and Vegard [RISC]. Atmel says that the name AVR is not an acronym and does not stand for anything in particular.

Atmel's family say that 8051 controller follows the von-nuemann architecture. because register to register operation not possible in all 8051 family. if it is harvard means, it must support register to register transfer.Hence it concludes that 8051 followed by von-nuemann or Princeton architecture...

The 8085 is an 8 bit microprocessor. It cannot directly handle 32 bit data. That said, it is possible to write a routine that can handle 32 bit data, just 8 bits at a time.

Firstly, it sounds like you are asking for general definitions, rather than differential definitions, which is problematic when the definitions are differential and context specific.

Cache miss:

not in cache, must be loaded from the original source

Cache hit:

was loaded from cache (no implication of what "type" of cache was hit).

cold cache:

The slowest cache hit possible. The actual loading mechanism depends on the type of cache (CPU cache could refer to an L2 (or L3) hit, disk cache could refer to a RAM hit on the drive, web cache could refer to a drive cache hit)

hot cache:

The fastest cache hit possible. Depends on mechanism described (CPU could be L1 cache, disk could be OS cache hit, web cache could be RAM hit in cache device)

Warm cache:

Anything between, like L2 when L1 is hot and L3 is cold. It is a less precise term and often used to imply "hot" when the performance is closer to "cold."

It means that it is manufactured under 65nm technology.

it is made up of semiconductor chip

It has a silver solution on the bottom of it and it helps draw the heat into the metal part of the heatsink and then spreads out between the thinner parts and then the fan blows on it helping it cool the heat faster.

You can use any LGA775 Pentium 4, Pentium D, or Celeron D with an 800, 533, or 400 Mhz FSB.

Neither. It is a computer processor.

step 1 learn how to write full sentences that make sense

step 2 google the cpu and it should tell you what kinda motherboard to use

Four beeps after installing a new CPU are a sign of memory error. You should try resetting your RAM.

The actual speed of a laptop processor of 1.8GHz i3 3rd generation is 1.8 million commands per second.

MSI has not produced many dual processor boards. The Athlon socket motherboard for MP processors is for 266 DDR FSB chips only. It may pose a problem if the user wanted to upgrade to something better, as the chip would likely not support a 333 FSB or beyond cpu.

However, there are some newer dual opteron motherboards that look promising. Try "googling" 'dual opteron motherboard' and see what results come up. Bear in mind that AMD is going to release a dual core CPU which, in effect, are two cpus on one chip.

x86 refers to any processor that is instruction-compatible with the Intel 8086 and higher. This includes the Pentium, Pentium II, Celeron, Pentium III, Pentium 4, Pentium D, Core Duo, Core 2 Duo, Core i7, Atom, AMD Athlon, Sempron, Athlon 64, Phenom, and Geode.

x64 is often used to refer to any x86 processor that has 64-bit extensions (x86-64). These include the AMD Athlon 64, late models of the Pentium 4, Pentium D, Core 2 Duo, Phenom, and certain Geode processors.

x32 is a retcon of the x64 term to apply to either 32-bit only processors or programs.

The central processing unit (CPU) of a computer does bothinput and output operations.

Planned x86 processors will have the SSE4 instruction set.

The direct memory access or DMA mode of data transfer is the fastest amongst all the modes of data transfer.In this mode ,the device may transfer data directly to/from memory without any interference from the CPU.The device requests the CPU through a DMA controller to hold its data,address and control bus so that the device may transfer data directly to/from memory.

Depends on what you mean by wear out, can a cpu life finish yes.

In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor.

"The Intel_4004is generally regarded as the first microprocessor, and cost thousands of dollars. The first known advertisement for the 4004 is dated November 1971 and appeared in Electronic_News. The project that produced the 4004 originated in 1969, when Busicom, a Japanese calculator manufacturer, asked Intel to build a chipset for high-performance desktop calculators. Busicom's original design called for a programmable chip set consisting of seven different chips. Three of the chips were to make a special-purpose CPU with its program stored in ROM and its data stored in shift register read-write memory. Ted_Hoff, the Intel engineer assigned to evaluate the project, believed the Busicom design could be simplified by using dynamic RAM storage for data, rather than shift register memory, and a more traditional general-purpose CPU architecture. Hoff came up with a four-chip architectural proposal: a ROM chip for storing the programs, a dynamic RAM chip for storing data, a simple I/O device and a 4-bit central processing unit (CPU). Although not a chip designer, he felt the CPU could be integrated into a single chip. This chip would later be called the 4004 microprocessor"
This is usually credited to Ted Hoff at Intel, the 4004.

Actually, the first commercial microprocessor was the AL1 developed by Four Phase Systems. See the Description of this chip on the Computer History Museum timeline: http://www.computerhistory.org/revolution/digital-logic/12/282/1523

yes the CPU on a computer is always hot while running. The accually CPU it self can get so hot in can couse burns. That is why there are always metal heatsinks to direct airflow and a fan that draws the warm air off. If you do not have a heatsink and a fan the CPU can burn up in almost 1 min.

230 voltage is used by the microprocessor

you addd 5plus 2

you cant actualy raise the CPU speed but just improve the speed of the cpu, one way on PC is to got to S trt --> Control Panel --> System and Security --> Power Options, then click on High performance under Plans,( if you dont see High Performance, click on Show additional plans)

socket 7 or socket A

No.
