CPU (Central Processing Unit) - A chip within the computer which controls the operation of all parts of the computer and decodes then executes program instructions., ALU (Arithmetic Logic Unit) - The part of the CPU responsible for arithmetic and logical operations, Register - A small area of memory within the CPU where data is stored temporarily to avoid the delay in copying to and from main memory,, MAR (Memory Address Register) - A register. It contains the address of the instruction currently being read from or written to main memory., MDR (Memory Data Register) - A register. It contains the instruction which has just been copied from main memory., Program Counter - A register. It contains the address of the next instruction to be fetched from memory. It is updated each time a new instruction is fetched to contain the address of the next needed instruction., Accumulator - A register. Stores the result of the last operation., Von Neumann Architecture - The design on which most computers are based. It defines several registers along with the fetch-execute cycle and how the CPU interacts with main memory., Fetch-execute Cycle - Instructions are fetched one by one from main memory, decoded, and then executed by the processor. This cycle repeats until the program is complete,
