When this machine code runs, the processor's circuits (adders inside the ALU) use logic gates to physically add 5 and 3 .
: Groups of flip-flops acting together to store larger data words (e.g., 32-bit or 64-bit data).

Modern computers rely on billions of microscopic electronic components called . A transistor acts as an electronic switch. When voltage is applied to the control gate, current flows through the switch, completing a circuit. Basic Logic Gates
Intermediate memory (L1, L2, L3) that sits between fast registers and slower RAM to speed up operations. 3. Bridging Hardware and Software: Assembly

: Circuits that perform binary addition. A Half Adder adds two single bits. A Full Adder can handle three bits, including a carry-in bit from a previous operation. By chaining full adders together, we can add large numbers (e.g., 32-bit or 64-bit integers).
An 8-bit adder circuit takes two 8-bit numbers (like 00000101 for 5 and 00000011 for 3) and outputs 00001000 (8). This is done entirely through interconnected AND, OR, and XOR gates.

The CPU retrieves an instruction from the computer's memory.
. They use a clock signal to store state, allowing the computer to "remember" previous data. Eindhoven University of Technology 🧠 3. Processors (CPUs): The Brain
Processors only understand machine language—strings of raw binary 0 s and 1 s. Writing software in binary or assembly language is slow, error-prone, and highly specific to one specific type of processor hardware. To bridge this gap, humans use high-level programming languages (like C++, Java, or Rust), and rely on to translate them. What is a Compiler?
