In a computer's CPU, the instruction fetch stage retrieves instructions from memory. The program counter (PC) holds the address of the next instruction to be executed, which is used to access memory. Once fetched, the instruction is then typically decoded and executed in subsequent stages of the instruction cycle. This process is essential for the sequential execution of programs.

What part in the computer Fetches and decodes instruction?
The part of the computer that fetches and decodes instructions is the Central Processing Unit (CPU), specifically within its control unit. The control unit retrieves instructions from memory, decodes them to understand what actions are required, and then sends signals to other components of the computer to execute those instructions. This process is fundamental to the operation of a computer, enabling it to perform tasks efficiently.
WHAT IS Instruction fetch?
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
Where does it begin when the microprocessor starts executes instructions?
During the start of execution, the microprocessor executes all instructions from BIOS. This in turn fetches the boot sector.
What are the relationship between cmos and bios?
The CPU depends on the BIOS to fetch instructions for processing and then to present it to the user after it is processed, The BIOS also depends on the CPU to process the information it fetches and sends back.
How does computers microprocessor work?
The basic computer has two parts: Random Access Memory (RAM) and a Central Processing Unit (CPU.) A microprocessor is a CPU that is built on a single chip. RAM is a place where many bytes are stored. One of the things that can be stored in RAM is a series of "instructions" that tell the CPU what to do. The series of instructions is called a "program." The CPU "fetches" one instruction from RAM, "executes" that instruction, then fetches and executes the next one, and so on. Exactly what the instructions in the program tell the computer to do determines how the computer will act at any given time.
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.
What is the computers 'thinking work' done in?
The basic computer has two parts: Random Access Memory (RAM) and a Central Processing Unit (CPU) RAM is a place where many bytes are stored. One of the things that can be stored in RAM is a series of "instructions" that tell the CPU what to do. The series of instructions is called a "program." The CPU "fetches" one instruction from RAM, "executes" that instruction, then fetches and executes the next one, and so on. That is all that computers do. Whether that qualifies as "thinking" is a very controversial question.
How does a prossesor work?
A processor is the "brain" of a computer, responsible for executing instructions. It fetches instructions from memory, decodes them into control signals, and executes them by performing arithmetic, logic, and other operations. The processor's performance is influenced by factors like clock speed, number of cores, cache size, and architecture.
What fetches decodes executes and stores?
the ram
