How does the CPU keep track of which instruction to execute next?
The instruction register holds a pointer to the current instruction (in working memory) while the next instruction register points to the next instruction (the first instruction immediately after the current instruction's operands). If the current instruction is a jump instruction, it can change the next instruction register, allowing the program to branch to a new instruction once the jump instruction is processed. The next instruction pointer is automatically moved into the current instruction register once the current instruction has been processed. The entire process of executing an instruction is known as the fetch-decode-execute cycle.
What is fetching in microprocessor?
1) Fetch is the first of two stages involved in computer processing. The processor operates by processing instructions in what is called the "fetch/execute cycle." The processor fetches (reads from memory) an instruction and then, depending on the instruction, executes it (takes some further action with it, such as shifting bits to the right or left). Then it fetches the next instruction, and so forth.
Where can you get a DS action replay instruction?
Go to google. Type in Action Replay Instructions. The first site will give you the answers you need.
Why is it that sometimes when you run a program it will execute the previous program instead the current open program?
because the previous program is the first one to be interpreted that's why you need to re run the program to open the current program that you want to open

Name the part of the computer that stores all information and software?
The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc). There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.
What was the first instruction on the instruction list?
move accumulator
How does the microprocessor work?
Suppose we give a 8-bit instruction ADD B to the microprocessor then this instruction is not at all understood by microprocessor as it only accepts binary inputs so first of all it stores the instruction in the INSTRUCTION REGISTOR then it decodes this instruction ADD B to its suitable binary code 80H in the INSTRUCTION DECODER.. after converting to 80H then the microprocessor understands that .. yes i have to add the content of the resistor B with that of A(accumulator) and store the result in the accumulator A this is a small example how microprocessor operates facing the instructions
3 stages in an intramural program?
There three stages in an intramural program are planning, execution, and evaluation. The first intramural sports departments were established in 1913 at the University of Michigan and Ohio State University.
