How does fetch decode cycle work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
What helps ribosomes decode messenger RNA?

Where is DNA decoded onto in protein synthesis?
DNA is first transcribed into mRNA in the nucleus of the cell. This mRNA then moves to the cytoplasm, where it is translated by ribosomes. The ribosomes decode the mRNA sequence and synthesize the corresponding amino acids into a protein. Therefore, protein synthesis occurs in the cytoplasm.
What do Fetch Decode and Execute mean in a microprocessor?
Fetch Decode Execute. This is the cycle that processors will follow. Fetch the Instruction, Decode it into machine code, Execute the commands
Is fetch decode execute cycle is used in coding?
No. Fetch-decode-execute is a machine state time paradigm, not a philosophy used in coding.
What are the stages of compilation?
fetch, decode and execute
What cycle is used by the CPU to execute instructions in a programs?
fetch,decode

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.
What are the 3 instruction cycles?
1. Fetch 2. Decode 3. Execute
What are the four steps in the instruction cycle?
1.fetch 2.decode 3.execute
What are the functions of the CU?
The function of the Control Unit is to Fetch, Decode, Execute and to Store information.
What is a CPU cycle?
The sequence of steps that a CPU performs.Also known as fetch-decode-execute cycle.
What is the Advantages and Disadvantages of von neumann computer architecture?
Disadvantages -Executes instruction serially. -Limited by the times it takes to process each instruction. -some registers are idle(not being used)during the fetch-decode-execute-reset-cycle. Advantages -Is that seperate data bus are not required. -program locality
What no of instruction will be execute by using only one clock pulse in 8085 microprocessor?
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
