Computer Architecture -

Far more than just a blueprint of wires and chips, computer architecture is the art and science of designing the interface between the physical machinery and the logical instructions that drive it. It is the "soul" of the computer—a complex system of trade-offs involving performance, cost, power, and complexity.

This is the "air traffic controller." It decodes the binary instruction fetched from RAM and translates it into control signals that tell the ALU, memory, and I/O devices what to do. Computer Architecture

John Von Neumann proposed the "stored-program concept" (the Von Neumann architecture), where both data and instructions live in the same memory space. While revolutionary, this created the infamous —the bandwidth between the CPU and memory is the limiting factor, not the CPU speed. Far more than just a blueprint of wires
