What are the four steps in the instruction cycle?
1.fetch 2.decode 3.execute
What are The CPU performs four steps in executing an instruction?
Three steps is probably minimal, and not really sufficient to describe the processing a CPU performs. If you have to use 3, probably fetch (the instruction), execute (the instruction) and store (write the results). However, this skips fetching the operands (if any). Most instructions require one or more operands. If you assume the instruction is already fetched, you might classify the three steps as fetch the operand(s) (read them from memory), execute the instruction (perform an operation on the operands) and store (write the results to memory). I think you will find it is more fetch, decode and execute are the three steps a CPU performs
Explain steps involve in instruction execution cycle?
The two-phase process for executing instructions on a typical CPU involves a fetch step and an execute step. Fetch is where the instruction is loaded from memory and execute is where the actions detailed in the instruction are carried out.

Basic steps used by the processor in instruction processing are?
1.Fetch the most instructions from memory. 2.Read an apparend if required by the instruction.(Apparend is a quantity to be operated as directed by its associated instruction.) 3.Execute the instruction.(Do what the instruction says.) 4.Write the result backe into memory.(If required by instruction.)
What is the relationship between instruction and micro operation?
1 macro can be defined as a cycle involve numbers of small steps to execute or to perform a task this small step is known as micro-opration micro is part of instruction 2.instruction is task performed by micro opration
What are the four steps of the machine cycle and describe what occurs at each step?
fetch decode execute and store in that order.... i do not know the description of each stage i need the answer to that myselfmachine cycle is also called instruction cycleCPU performs following steps to execute an instructionFetchDecodeExecuteStoringFetchload instruction from the memory to execute.this operation performed by control unit.Decodedetermine what the instruction is telling the computer to do,and what operation should be taken.Executeafter decoding and getting the required result,CPU finally execute instruction by ALU(arthematic logic unit).Storingthe process of writing the result to memory is called storing or the process of storing the generated result to the main memory.
What are the 4 steps that describes how a computer works?
I'm not completely sure what you mean as there are many possibilities. One possibility is: Fetch, Load, Execute, Store.
How would you describe the fetch execute cycle?
Fetch Execute Cycle A more complete form of the Instruction Fetch Execute Cycle can be broken down into the following steps: 1. Fetch Cycle 2. Decode Cycle 3. Execute Cycle 4. Interrupt Cycle 1. Fetch Cycle The fetch cycle begins with retrieving the address stored in the Program Counter (PC). The address stored in the PC is some valid address in the memory holding the instruction to be executed. (In case this address does not exist we would end up causing an interrupt or exception).The Central Processing Unit completes this step by fetching the instruction stored at this address from the memory and transferring this instruction to a special register - Instruction Register (IR) to hold the instruction to be executed. The program counter is incremented to point to the next address from which the new instruction is to be fetched. 2. Decode Cycle The decode cycle is used for interpreting the instruction that was fetched in the Fetch Cycle. The operands are retrieved from the addresses if the need be. 3. Execute Cycle This cycle as the name suggests, simply executes the instruction that was fetched and decoded
What are the steps in applying makeup?
They are instruction on how to apply the make-up properly and I believe that there are steps. I can't tell you myself but if you refer to Michelle Pham's make-up video tutorials on YouTube, you will get the idea.
What is a cycling machine?
Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.
How can one learn the steps for creating an instruction manual?
One can learn the steps for creating an instruction manual from a variety of sources. The most important thing to remember when beginning to create an instruction manual is to be intimately familiar with the product.
