Introduction

This video is the first in a free, complete CCNA (Cisco Certified Network Associate) course. It introduces the course structure, target audience (anyone wanting to pass the CCNA 200-301 exam or learn about computer networking), and begins with a lesson on fundamental network devices.

Key Takeaways

• The course is a free, comprehensive guide to passing the CCNA 200-301 exam, including lectures, quizzes, flashcards, and practice labs.
• A network allows nodes to share resources. Nodes include clients, servers, routers, switches, and firewalls.
• Clients access services provided by servers; a device can function as both client and server depending on the interaction.
• Switches connect devices within a LAN (Local Area Network); routers connect LANs and facilitate communication across the internet.
• Firewalls control network traffic, protecting networks from unauthorized access; they can be hardware (network) or software (host-based). Next-generation firewalls offer advanced filtering capabilities.
