What refers to the amount of time it takes a CPU to execute an instruction and store the result?
The execution cycle.

How do the basic computer components work together to execute an instruction?
The input devices receive the instruction from the user, which is then fed into the processor. The processor then executes the instruction and displays the result on the screen or other appropriate output device.
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 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 is 6 stage instruction pipelining?
1. FI (fetch instruction) - get the next instruction 2. DI (decode instruction) - decode the opcode and operands 3. CO (calculate operands) - calculate EA of the operands 4. FO (fetch operands) - fetch operands from memory (not necessary for register data) 5. EI (execute instruction) - execute instruction storing result if necessary 6. WO (write operand) - write the result in MEM
What are the steps to properly and completely execute an instruction?
1 Fetch Instruction from Memory 2 Decode Instruction and Fetch Operands 3 Perform ALU Operations 4 Memory Access (for load/store)5 Store ALU result to register file 6Update PC
What are facts about the fetch execute cycle?
The fetch-execute cycle is the fundamental process by which a computer retrieves and executes instructions from memory. It consists of several stages: fetching the instruction from memory, decoding it to determine the required action, executing the instruction, and then writing back the result if necessary. This cycle repeats continuously as long as the computer is running a program. It is essential for the operation of the CPU and influences overall system performance.
What are the 4-step machine cycle and describe what occurs at each step?
The 4-step machine cycle consists of Fetch, Decode, Execute, and Store. Fetch: The CPU retrieves an instruction from memory, using the program counter to determine the address. Decode: The fetched instruction is interpreted to understand what action is required, identifying the operation and the operands involved. Execute: The CPU performs the operation specified by the instruction, which may involve arithmetic calculations or data manipulation. Store: Finally, the result of the execution is written back to memory or a register, completing the cycle before moving on to the next instruction.
Is the amount of time it takes to retrieve an instruction and complete the respective command?
The time it takes to retrieve an instruction and complete the respective command is known as instruction latency. This includes factors like the fetching of the instruction, decoding it, executing it, and storing the result. The overall latency can impact the performance of a computer system.
The proper sequence of actions in a machine cycle is?
The proper sequence of actions in a machine cycle typically includes fetch, decode, execute, and writeback. During fetch, the CPU retrieves instructions from memory. In decode, the CPU translates the instructions into signals the computer can understand. The execute stage involves actually carrying out the instruction, and writeback stores the result back into memory if needed.
What is albumin in urinalysis?
Albumin refers to the amount of water soluble protein in the urine. A normal result would be negative.
ADD instruction of 8085?
The ADD instruction in the 8085 microprocessor is used to add the contents of a specified register or memory location to the accumulator (register A) and store the result back in the accumulator. It can be used with registers like B, C, D, E, H, and L, or with a memory address specified. The operation affects the flags in the status register, reflecting conditions such as zero, carry, and parity. The instruction takes 1 byte and 1 machine cycle to execute.
What is the difference between three address instruction and two address instruction?
the differebce between three address instruction and two address instruction is three adresss instructoion two address instruction 1) here 3 oprarend fields are used 1) here 2 oprerand fields are used 2) the result is stored in 3rd operand 2) here the result is stored in 2nd oparend
