🧠 Background Theory of Raspberry Pi
🔌 What Is Raspberry Pi?
Raspberry Pi is a low-cost, credit-card-sized computer developed by the Raspberry Pi Foundation in the UK. It runs a full operating system (usually Linux-based) and supports:
USB peripherals
HDMI display
Ethernet / Wi-Fi
GPIO (General Purpose Input Output) pins
🏗️ System Architecture Overview
At its core, Raspberry Pi consists of:
SoC (System on Chip) – CPU + GPU + RAM controller
RAM – Shared between CPU and GPU
Storage – microSD card (or SSD via USB)
I/O Interfaces – USB, HDMI, CSI, DSI, GPIO
📌 Unlike traditional PCs, Raspberry Pi uses ARM architecture, which affects software compatibility and performance tuning.
📘 Technical Definition
📌 Engineering Definition
Raspberry Pi is a single-board computer (SBC) that integrates processing, memory, storage interfaces, and I/O peripherals into a compact embedded system designed for education, prototyping, and industrial applications.
