The programs (instructions) are saved on a computer's hard disk; to actually execute the instructions, they are copied into RAM. From there, they are basically fetched, one instruction at a time, into the CPU, where they are executed.

∙ 6y agoIn a variety of places... The initial start-up instructions are held in the BIOS chip... The RAM chips (where programs are loaded for use) are temporary storage that is erased when the computer is turned off... The hard-drive - is where programs and data are held permanently - until they're erased.

What is a computer program made of?
A computer program contains instructions, to be executed by a computer.
A set of instructions executed by the computer?
Command Language is the answer.
Why do you need multiprocessor environment?
for improving the efficiency of the computer system.In multiprocessor environment , instructions can be executed parallely.
What is called michine language?
Machine language are the set of instructions that are executed directly by the central processing unit of the computer. It include 0 and 1.
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 does the term control flow refer to?
Control flow refers to the order in which instructions or statements of an imperative program are executed. This term is widely used in computer science.
What stores instructions waiting to be executed by the processor?
memory
Stores instructions waiting to be executed by the processor?
its memory.
What is the term for instructions that tell a computer what to do?
The instructions for a computer are called programs.
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 unit of computer does implement the instructions?
The CPU of the computer implements the instructions. Instructions are given as per programming. It depends on the type of software a computer is programmed to.
How does computer technology impact the planning of instructions?
Computer technology impacts the planning of instructions by organizing them. Computer technology can distribute instructions to the recipients within seconds.
