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 full, partial, and hybrid mesh topologies, compare hub-and-spoke and star topology for infrastructure mode with ad hoc wireless, and note centralized versus decentralized management for reliable and redundant networks.

Explore copper media, including coaxial and twisted pair cables, their inner conductors, jackets, shielding, emi resistance, and connectors like rj-6, rj-59, and f-type.

Explore media and cable distribution systems, from copper wiring and 110 blocks to patch panels and fibre optic jacks, and understand crosstalk and high-speed cabling considerations.

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.

Explore layer 2 devices, MAC addressing, and switches shaping frames, then examine layer 3 with IP addresses (IPv4/IPv6), routing tables, and static or dynamic routing basics.

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.

Explore how routers and multilayer switches separate broadcast domains, forward between subnets with routing tables, and use static, default, and dynamic protocols (vector, link-state, hybrid) for longest-prefix decisions.

Explore routing fundamentals, distance-vector and link-state protocols, including RIP, OSPF, IS-IS, EIGRP, and BGP, and how they handle convergence and topology changes.

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.

Explore routing fundamentals, including private and public IP addressing, port address translation, and multicast concepts with IGMP versions and multicast routing to form a multicast distribution tree.

Learn protocol independent multicast concepts, including multicast distribution trees, flood and broom behavior, and the evolution from shared to shortest path trees in PIM sparse mode.

Explore wireless networks by describing components, frequencies, and specifications, and compare ad hoc peer-to-peer communication with infrastructure using access points and gateways to connect devices to the internet.

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.

Explains network security focusing on integrity via hashing and hash digests, using SHA variants and MD5, and covers confidentiality and availability attacks including DDoS and malware.

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