difference between micro operation and microinstruction
An instruction cycle.
Control Unit

In an instruction cycle with indirect addressing, the CPU fetches the instruction, decodes it to determine the memory address of the operand stored in a register, fetches the operand from the memory location pointed to by the register, and executes the instruction using the operand. Finally, the CPU stores the result back in memory if needed. This extra step of fetching the operand based on the indirect memory address adds complexity to the instruction cycle.

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.
Microprocessors are electronic chips that read and execute instructions to perform tasks in a computer or electronic device. They contain an arithmetic logic unit (ALU), control unit, and memory. The ALU performs mathematical operations, the control unit manages data flow, and memory stores instructions and data for processing. When powered on, the microprocessor fetches instructions, decodes them, executes the operation, and stores the result. This process repeats until all instructions are executed.
During the machine cycle, the processor fetches instructions from memory, decodes them to understand the operation, executes the operation by performing the necessary calculations or data transfers, and then writes the results back to the appropriate location in memory. This process repeats for each instruction in a continuous loop to carry out the commands effectively.
During the start of execution, the microprocessor executes all instructions from BIOS. This in turn fetches the boot sector.
how a plc stores a programme and executes it
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.
