Editing The Von Neumann Architecture (section)

== <span style="color: #FFFFFF;">Remembering</span> ==
* '''Von Neumann Architecture''' — A computer architecture based on the "Stored-program" concept, where instruction data and program data are stored in the same memory.
* '''John von Neumann''' — The Hungarian-American polymath who described the architecture in his "First Draft of a Report on the EDVAC."
* '''The Four Main Components''':
# '''CPU (Central Processing Unit)''' — The "Brain" that performs math and logic.
# '''Memory (RAM)''' — The "Workspace" that stores the program and the data.
# '''I/O (Input/Output)''' — How the machine talks to the world (Keyboard, Screen).
# '''The Bus''' — The "Wires" that move data between the CPU and Memory.
* '''Stored-Program Concept''' — The idea that a computer's "Instructions" are just another type of "Data" (Numbers) that can be changed easily.
* '''Control Unit (CU)''' — The part of the CPU that "Directs" the flow of traffic.
* '''Arithmetic Logic Unit (ALU)''' — The part of the CPU that does the "Actual Math" (+, -, *, /).
* '''The Fetch-Decode-Execute Cycle''' — The "Heartbeat" of a computer: it "Fetches" an instruction from memory, "Decodes" what it means, and "Executes" it.
* '''Registers''' — Tiny, ultra-fast memory spots inside the CPU used for "Immediate work."
* '''Von Neumann Bottleneck''' — The "Traffic Jam" that happens because the CPU can think much faster than the "Bus" can move data from memory.
