LAN (Local Area Network)
LAN (Local Area Network)
A network covering a small geographic area like a home, office, or campus. It has high-speed bandwidth and single administration.
WAN (Wide Area Network)
WAN (Wide Area Network)
A network connecting LANs over large distances like cities or countries. Usually managed by multiple providers and has slower speeds.

Study Notes
Introduction to Networks
- Networks enable global communication for learning, work, and entertainment.
- Communication methods include texting, social media, online collaboration, blogging, and gaming.
Types of Networks
- LAN (Local Area Network): Covers a small area (home, office) with high speed and single administration.
- WAN (Wide Area Network): Spans large geographic areas (cities, countries), using multiple providers and slower speeds.
- Internet: A worldwide network combining LANs and WANs, connected via copper, fiber optic, and wireless technologies.
Network Components
- End Devices: Devices initiating or receiving messages (computers, phones).
- Intermediary Devices: Manage data flow (routers, switches, firewalls).
- Media Types: Transmission methods like copper cables, fiber optics, and wireless.
Network Architectures
- Fault Tolerance: Redundant systems minimizing failures.
- Scalability: Ability to expand without performance loss.
- Quality of Service (QoS): Prioritizes important data like video and voice.
- Security: Protecting data and infrastructure (confidentiality, integrity, availability).
Networking Trends
- BYOD (Bring Your Own Device): Employees accessing company resources with personal mobile devices.
- Cloud Computing: Data storage and access via the internet (public, private, hybrid).
- Collaboration and Video Communication: Tools like Cisco WebEx and TelePresence.
- Smart Homes: Integrating technology into appliances.
Security
- Threats: External (viruses, hacking, denial-of-service attacks) and internal (employee errors or deliberate actions).
- Solutions: Home networks (antivirus, firewalls); large networks (access controls, intrusion prevention systems, VPNs).
Key Terms
- Topology: Network layout (physical or logical).
- NIC (Network Interface Card): Connects a device to the network.
- Packet Switching: Dividing data into packets improving fault tolerance.
