Redes, TCP/IP e Wireshark!

Explore the fundamental concepts of computer networks and gain a solid understanding of how they work. This course delves into the core components and protocols that power modern communication.

Network Types:

• PAN (Personal Area Network): Learn about networks for personal devices.
• LAN (Local Area Network): Understand networks within a limited area like a home or office.
• MAN (Metropolitan Area Network): Discover networks spanning a city.
• WAN (Wide Area Network): Explore networks covering large geographical distances.
• Internet: Get a comprehensive overview of the global network.
• Cloud Computing: Understand how networks enable cloud services.
• IoT (Internet of Things): Learn about the network connecting everyday devices.

Network Architecture & Elements:

This course covers the journey of data, from the user host to the network's backbone connections with telecommunication providers. We'll explore the key elements that make up a network infrastructure.
