Microprocessors
A microprocessor is the heart of any computer, whether it is a server, a desktop machine, or a laptop. This single chip contains the arithmetic, control, and logic circuitry necessary to interpret and execute computer programs.

Why we use computer why computer is usefull what are the benefits of computer?
They operate with amazing speed, reliability, consistency, and accuracy
Spellcheck is great too. Ahem.
Hmmm... another homework question. It never ceases to amaze me how many kids don't want to do their homework so they just ask the questions here.
Depends on the benchmark used to measure:
- KOPS or KIPS - measure of instructions executed per second
- MFLOPS - measure of floating point operations per second
- Whetstones - measure of overall floating point performance
- Drystones - measure of overall integer performance.
- Livermore loops - measure of computing and looping performance
- etc. etc.
Never measure CPU speed by the clock speed. Different architectures and implementations of the same architecture can give dramatically different speeds on real applications even with the CPUs running on the same clock.
One example of this occurred when Apple first started making Macs using the PowerPC. Power Macs could run in software emulation of the Intel Pentium Windows applications much faster than the existing PCs, even though the PCs operated on faster clock speeds and were running the code native.
Which memory module has a front side bus speed of 200 MHz?
If you are referring to standard RAM modules for a computer I believe you're looking for "PC1600" DDR ram. Not DDR2 or 3, just plain DDR ram.
Hope this helps!
What is the difference between Branch Save address Branch unconditional?
Branch Save Address saves the current program counter, usually in the first memory location of the subroutine that you are branching to so that the main routine can be later resumed at the exact spot that you branched from.
Branch unconditional on the other hand does not save the program counter, and therefore provides no way to return to your previous location.
What is the difference between 2.66 dual core and 64bit dual core?
The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.
Which uses more power a desktop or laptop of the same processor speed?
The desktop would, I would think, as it is bigger and has more space for that kind of power.
This is correct but not for that reason (desktops are mostly empty space). Laptops are designed to use low power and be portable so they uses more expensive parts that use less power.
What allows the processor to communicate with peripherals?
The key for any hardware piece to work with others is the SOFTWARE. That is why anything you buy for your computer (graphics cards, hard drives, etc.) it comes with software (or the driver) to help the computer recognize it and use it for the function its meant to be used for. I hope this is what you were looking for.
What is an explanation of in brief microcomputer?
A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC , a computer designed for an individual. A microcomputer contains a microprocessor (a central processing unit on a microchip ), memory in the form of read-only memory and random access memory , I/O ports and a bus or system of interconnecting wires, housed in a unit that is usually called a motherboard .

In an ascending hierarchy of general computer sizes, we find:
- An embedded systems programming computer, which is embedded in something and doesn't support direct human interaction but nevertheless meets all the other criteria of a microcomputer
- Microcomputer
- workstation , as used to mean a more powerful personal computer for special applications
- minicomputer , now restyled a "mid-range server"
- mainframe or mainframe computer, which is now usually referred to by its manufacturers as a "large server"
- Supercomputer, formerly almost a synonym for "Cray supercomputer" but now meaning a very large server and sometimes including a system of computers using parallel processing
- A parallel processing system is a system of interconnected computers that work on the same application together, sharing tasks that can be performed concurrently
What is the need of microprocessor in electronics?
because with the help of microprocessors we need not to solve large no. of equations every rime as we do with gates..
How do you find out what kind of CPU you have ie make and speed?
Right Click "My Computer", Select Properties, Select General Tab.
What processors will work with your Abit IS7-V2 motherboard?
The two major brands of personal computer CPUs are AMD and Intel. A distant second runner up is Via, which makes CPUs for netbooks and other low-power applications. These all manufacture CPUs using the x86 and x86-64 instruction set.
Advantage of arm processor over other processor?
The primary advantage of the Advanced RISC Microprocessor (ARM) architecture is that it was designed by BBC Micro with the primary goal of providing a reasonably powerful processor that operates with minimal power dissipation (heat), making it ideal for use in laptops, cell phones, tablets, and other small often battery powered devices.
How does microprocessor keep instraction in main memory?
It doesn't.
Main memory is usually volatile (that is, it "forgets" when power is removed).
Most microprocessor systems keep a "bootloader" which is a special type of program located in memory that is available when power is applied. These days, that is usually Flash memory.
So, a typical microprocessor boot sequence is that the microprocessor places a known starting address on the Flash's address lines. The data that is returned is then executed. This data forms a basic program which copies from the Flash memory into main memory. Control then shifts to the main memory when the Flash has been completely read.
There may be additional aspects to the booting process, such as the second-stage boot loader which is responsible for loading the operating system, usually from a disk drive rather than Flash.
"Single core" refers to the computer's main chip having a single processor. Newer models, such as Intel's i3, i5 and i7, have multiple processors (2, 4, or 6 processors), usually called multiple "cores", on a single chip.
GHz refers to the clock speed of each individual processor. It gives you a rough idea of how fast it can process data. However, the processing speed will also depend on other factors.
its an USART(universal synchronous and asynchronous receiver and transmitter) used for serial data transfer
Why microcomputer system based on 8 bit microprocessor have 64K memory?
Even though the 8085 is an 8 bit microprocessor, it can address 64K memory, because it has a 16 bit address bus.
If your cpu is broken will the cpu fan work?
The fan will work - but it will spin constantly - as it would have no data to rely on to regulate the temperature of the CPU.
Is a touch screen an input device?
Its more of an bidirectional device......it shows u the output graphic data as well as helps u select ur option.........
What is the impact of system speed on microprocessor bus?
if the processor is of 32 bit and it contains address bus of 323 bit, then it can fetch the instruction in one clock
(so faster speed)else if it has 16 bit address bus then it has to fetch the instruction(32 bit) (as processor is of 32 bit)then it has to wait for 2 clocks in 1st clock 16 bit of instructions will be fectchec and then in next clock the remainging will be fetched, so slower speed.(Regards)
Differences between virtual memory and cache memory?
Virtual memory is defined as an abstraction of the main memory that extends the available computer memory by storing parts of content RAM that are not active. Cache memory is where data that is accessed often is stored so you are able to have quick access to it.
