Networking Full Course & Network + certification

Define physical and logical topology to show device connections, media, and traffic flow, then outline bus, ring, star, and hub and spoke topologies with their redundancy notes.

Explore the osi networking model from layer 1 physical characteristics to layer 3 transport, covering IP datagrams, ICMP, ARP, and TCP/UDP/RTP, plus application layer interfaces.

Understand the OSI model's presentation layer, including data formatting and encryption. Learn how it negotiates transfer syntax for the application layer and enables services like file transfer and email.

Learn how administrative distance and routing metrics determine which routing protocol a router trusts, covering connected and static routes and port address translation in NAT.

Learn how wireless networks use access points and ESS to provide coverage, understand IBSS, mesh, and AP placement to avoid interference and enable roaming.

Explore how heat maps measure wireless coverage, extend reach with range extenders, and compare fixed, omni directional, and uni directional antennas; learn direct sequence spread spectrum and frequency hopping.

Examine wireless networking essentials, including frequency hopping spread spectrum, orthogonal frequency division multiplexing, 2.4/5 ghz bands, channel planning (1, 6, 11), and csma/ca with wpa2 aes security.

Explore how rogue access points capture data from users connected to them, and assess the risks of unsecured wireless networks and reconnaissance in real-world networking scenarios.

Explore network security fundamentals, emphasizing the CIA triad of confidentiality, integrity, and availability, and explain symmetric and asymmetric encryption with DES, 3DES, RSA, and PKI.

Explore multi-factor authentication methods and geo fencing concepts used to secure logins, followed by firewall fundamentals, including packet filtering, stateful inspection, and NAT.
