Instruction execution involves fetching, decoding, and executing instructions in a CPU.
Different addressing modes affect how operands are accessed in memory.
Interrupts allow CPUs to temporarily halt the execution of a program to handle other tasks.
The process in which a CPU fetches an instruction from memory, decodes it to determine the operation, and executes the instruction.
Methods used to specify the operands for instructions, including direct, indirect, and immediate addressing.
Signals that temporarily halt the CPU's current operations to address an immediate task, such as responding to user input.
