Why is it that the instructions being executed must be in physical memory of the computer?
When a computer gets ready to execute the next instruction, it pulls it out of memory of some sort or another. first it tries it's local high speed cache RAM, usually a part of the CPU chip. If it's not there, then it looks in the slower speed RAM. If it finds it there, the memory controller pulls a block of memory from RAM to cache then executes it there. If it doesn't see it in RAM, it looks for it in virtual memory, which is actually a part of the hard disk drive. When it finds it there, it pulls a block into RAM, then into Cache memory, where it is executed. Actually, the move from virtual memory to RAM is done way ahead of time, as the controllers see that the computer might need that block of memory in the near future. So you can see, all the instructions are executed in the small high speed cache RAM. This is done for speed. If all the instructions were executed in RAM, as computers once did, they would be 10 times slower. A lot of computer design is optimizing the memory controllers so that almost all of the instructions are executed out of high speed cache, and the processor rarely has to wait for the cache to fill up. If the computer executed out of hard disk space, it would be thousands of time slower.
What else can I help you with?
Stores instructions waiting to be executed by the processor?
its memory.
What stores instructions waiting to be executed by the processor?
memory
What assembler do for system?
An assembler takes abbreviated names for computer instructions, like "MOV", and turns them into the numeric bytes which, when loaded into memory, can be executed by the CPU.
What Consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data information?
Memory
What is physical memory?
Physical memory is a term used to describe the amount of memory [RAM] installed in your computer.
Is ram permanent memory that assists with computer start up?
RAM is used for storing the start-up instructions on the computer. This serves as the memory of the computer which will retrieve such instructions.
What is the difference between physical memory and available memory?
Physical memory is how much total memory your computer actually has. Available memory is what memory you have that is not being used.
What is physical dump memory?
gotta multiply it by 23 to the 3rd power. how do you like me now dick
WHAT IS Instruction fetch?
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
Once in memory the computer can carry out or the instructions in a program?
execute
What consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data (information).?
Memory
What do you call electronic components that store instructions waiting to be executed?
It's called CPU cache of level one.
