What are the 3 main components of the von Neumann architecture?
CPU, Main Memory, I/O Modules.
What does the CPU do?
Interprets instructions, performs calculations/logic, and controls the system.
What are the 3 main parts inside the CPU?
Control Unit (CU), Arithmetic Logic Unit (ALU), Registers.
What does main memory store?
Both instructions and data in binary form.
What do I/O modules do?
Handle communication between the computer and the external environment (input & output devices).
What is the key idea of the von Neumann architecture?
Instructions and data are stored together in main memory (stored-program concept).
What are the 4 basic computer functions?
Data processing, Data storage, Data movement, Control.
How does the CPU interact with memory?
Reads instructions/data from memory and writes results back to memory.
How does the CPU interact with I/O modules?
Sends/receives data to and from input/output devices.
