Microprocessors

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).

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

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.

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.

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.

Depends on the processor.

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

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.

avr is high speed cmpar to 8051.in 8051 there are less number of instructions

There are 6 general purpose Registers and Two special purpose registers:

General purpose registers(8 bit basically) are B,C,D,E,H,L and SPECIAL Purpose resisters are STACK PONITER,PROGRAM COUNTER these two are 16 bit registers.

If u want make general purpose registers as 16 bit registers, the combination is BC,DE,HL these are 16 bit pair registers

A CPU or Central Processing Unit is generally what is meant by the term microprocessor. Sometimes microprocessor can refer to additional hardware, but by and large,

CPU = microprocessor.

It performs arithmetic and logic operations within the microprocessor.

The speed of a moders computer is measured in MHz for RAM and GHz for Processors. 1 Hert is 1 occilation in 1 second, in a computer the clock speed of a processer is how many times per second it can make a binary calculation.

because it has four internal register and four external data bus

8085 is a 8 bit microprocessor designed by Intel.

Because it makes the CPU run hotter

Data bus

On the spreadsheet go to top of page

and click on Insert and the the sixth choice down is Symbol...

The box will appear with many many symbols

- it is the second symbol in the eighth row

and is called SUPERSCRIPT TWO

It looks like ²

Dual Core is better as it has two processing cores, Higher Clock Speed, Bigger FSB, Bigger Cache and it is built for multitasking but it does not mean that Centrino is bad as it is designed for NOTEBOOK Computer and does not give lower performance.

Guy above me is wrong

He asked about Centrino duo which IS a dual core. The Centrino platform is going to be a LOT faster than the Pentium Dual-Core. Centrino means you're getting a Core 2 Duo processor, Intel chipset, and Intel wireless. Core 2 Duo processors are much faster than Pentium Dual Core processors.

These 2 guys above me are wrong... na just kidding i just really wanted to say that :D

virtual memory

Case, Power Supply and Motherboard

The case must support the form factor of the motherboard, and the motherboard must support the CPU socket type for any given CPU.

processor contain three modes.

1.Real mode -When PC in DOS programing.

2.Protected Mode -When PC operating system mode

3.virtual mode real mode - when PC in protected and real mode conmmenly.
