Moore's Law

Highlighting exponential growth in computing power.

In 1965, Gordon Moore predicted that the number of transistors on a single chip would double every two years, while costs halved. This exponential growth shrunk computers from room-sized giants (like ENIAC) to the powerful microchips found in your smartphone today.

Microprocessors & Microcontrollers

Explaining modern CPUs and embedded systems.

With advancements in technology, the physical size of the CPU reduced dramatically. When a CPU is placed on a single microchip (LSI/VLSI), it is called a microprocessor.

A microprocessor is the "brain" of a general-purpose computer. It processes instructions but relies on external memory (RAM/ROM) and Input/Output devices to function.

Processor vs. Controller

Side-by-side of microprocessor vs microcontroller chip structure.

clean side-by-side comparison diagram, consistent visual treatment for both sides, same scale and style, pastel color coding to distinguish categories, elegant typography, white background, generous whitespace. On the left side titled 'Microprocessor': A chip containing only the CPU (ALU, CU, Registers), with arrows pointing outside the chip to separate external blocks for RAM, ROM, and I/O. On the right side titled 'Microcontroller': A single, larger integrated chip boundary that internally houses the CPU, RAM, ROM, and I/O ports all communicating via an internal Bus System.

A microprocessor requires external components, while a microcontroller packs everything into a single chip.
