SBCs (Single Board Computers): Designed as standalone, small-form-factor computers. They often include:
Display Interfaces: HDMI, DisplayPort, etc.
Input Connections: USB for keyboards, mice, etc.
General Purpose Functionality: Can run a full operating system for wider applications.
Controller Boards: Focus on controlling specific hardware or systems.
Limited direct I/O: Limited connectors for displays/input devices.
Specialized tasks: Designed for embedded applications within larger systems.

SSL/TLS Secures Web Traffic: HTTPS builds upon HTTP, adding the encryption provided by Secure Sockets Layer (SSL) or its successor, Transport Layer Security (TLS).
Other Protocols Have Different Purposes:
IPSec: Secures IP traffic at a network level, can be used alongside TLS.
SNMPv3: Management protocol, offers security features, but not the primary mechanism in HTTPS.
SSH: Secure remote shell, unrelated to web data encryption.

TLS (and SSL): References of their role in HTTPS and how they provide encryption for web communication.
HTTPS Overview: Materials showing how TLS fits into the overall HTTPS architecture.

Smart Building Core Benefit: Smart building technologies primarily aim to optimize a building's operational efficiency through automation and data-driven insights.
Efficiency Examples:
Energy Management: Automated lighting and HVAC control based on occupancy and environmental conditions.
Maintenance: Predictive maintenance through IoT sensors reduces downtime.
Space Utilization: Optimization of space allocation based on real-time usage patterns.

LoRa: Refers to the physical layer chirp spread spectrum (CSS) modulation, enabling long-range, low-power communication.
LoRaWAN: An open MAC layer protocol that builds on LoRa, defining network architecture, device management, and data routing for large-scale LoRa networks.
