Von Neumann Architecture Stored-Program Computer
Central Processing Unit Memory
Instruction Fetch Instruction Decode
Instruction Execution Control Unit

 

A computer that stores program instructions in its memory along with data, allowing the instructions to be treated as data and executed by the CPU. A computer architecture where where programs and data are stored in the same memory and can be executed sequentially by the CPU
The component of a computer that is used to store data and program instructions for immediate use by the CPU. The primary component of a computer that performs most of the processing inside the computer, including performing arithmetic, logical, control, and input/output operations.
The process of determining the exact operation to be performed and the operands of a given instruction. The process of retrieving a program instruction from memory so that it can be executed by the CPU.
The component of a CPU that manages the execution of instructions, coordinates the activities of the other components, and controls the flow of data within the CPU. The process of carrying out the operation specified by an instruction using the data from registers and memory.

 

Arithmetic Logic Unit (ALU) Input/Output (I/O)
Bus Control Bus
Data Bus Address Bus
Register Accumulator

 

The process of transferring data between the computer and external devices, such as keyboards, monitors, and printers. The component of a CPU that performs arithmetic and logical operations, such as addition, subtraction, multiplication, division, and comparison.
A bus in a computer architecture that is used by the CPU to communicate with other hardware components and control their operations. A communication system that transfers data between components in a computer.
A bus in a computer architecture that is used to specify the memory address in read or write operations. A bus in a computer architecture that is used to transmit data between the CPU and other hardware components.
a special-purpose register in a CPU that is used for arithmetic operations and holds the results of calculations a small amount of storage in the central processing unit (CPU) that is used to store data or instructions temporarily during program execution

 

Program Counter Memory Data Register
Memory Address Register Instruction Register
System Bus

 

a register that stores data being transferred to and from the memory unit a register that keeps track of the address of the next instruction to be executed in a program
a register that holds the currently executed instruction in a CPU a register that holds the address of a memory location currently being accessed by the CPU
A communication pathway that connects the various components within a computer system, allowing data and control signals to be transferred between them.
