This episode focuses on Port Address Translation (PAT), often called overload NAT, which extends NAT by allowing multiple devices to share one public IP using different port numbers. PAT is critical …

This episode introduces Network Address Translation (NAT), a process that allows multiple internal devices to share a single public IP address. It explains the core function of NAT in conserving IPv4…

This episode explains the difference between public and private IP addresses and why the distinction is important for both exam and real-world environments. Public addresses are globally routable and…

This episode introduces the fundamentals of IP addressing and subnetting, two of the most critical skills for the Network Plus exam. It explains how IP addresses identify hosts on a network and how s…

This episode introduces Ethernet standards over fiber optic cabling, which enable high-speed communication across longer distances than copper. Standards such as 1000BASE-LX, 10GBASE-SR, and 40GBASE-…

This episode explains the Ethernet standards that operate over copper cabling, from early Fast Ethernet to Gigabit and 10 Gigabit Ethernet. It describes how cable categories, frequencies, and distanc…

This episode highlights the importance of proper cable management, distribution panels, and punchdown blocks in maintaining organized, functional networks. It explains how patch panels centralize con…

This episode explains media converters, devices that enable communication between different types of physical cabling, such as copper to fiber or single-mode to multimode fiber. Media converters play…

This episode introduces transceiver modules, which enable switches, routers, and other network devices to interface with fiber or copper cabling. Standards such as SFP, SFP+, QSFP, and GBIC are expla…

This episode focuses on the various connector types used with fiber and copper cabling. For fiber, common connectors include ST, SC, LC, and MTP/MPO, each with specific use cases and physical charact…

This episode explains the differences between single-mode and multimode fiber, two types of optical cabling defined by how light travels through the core. Single-mode fiber, with its narrow core, sup…

This episode introduces fiber optic cabling, which transmits data as pulses of light rather than electrical signals. Fiber provides high bandwidth, long-distance capability, and immunity to electroma…

This episode introduces the TIA/EIA-568A and TIA/EIA-568B cabling standards, which define how twisted pair cables are terminated for reliable network communication. It explains the wire color codes a…

This episode covers coaxial and twinaxial cables, two copper-based media types that still appear in both exam questions and some practical environments. Coaxial cable uses a central conductor surroun…

This episode examines twisted pair cabling standards, including Category 5, 5e, 6, 6a, and higher classifications. Each standard is defined by its maximum transmission speed, frequency, and distance …

This episode introduces transmission media, focusing on copper cabling as one of the most widely used network media types. It explains how copper cables transmit electrical signals and introduces the…

This episode explains the variety of network provider links that organizations use to connect geographically dispersed sites. It introduces technologies such as satellite communications, microwave, D…

This episode introduces Network Function Virtualization (NFV), which replaces traditional hardware-based appliances like routers, load balancers, and firewalls with software-based equivalents. NFV en…

This episode explores virtual network interfaces and components, which allow logical networking functions to operate independently of physical hardware. A virtual network interface card (vNIC) enable…

This episode covers network entry points, specifically the concepts of demarcation points and smartjacks. A demarcation point is where the responsibility of the service provider ends and the customer…
