| Old Topic (Pre-2020) | New Topic (2026 Edition) | |----------------------|--------------------------| | DDR3 RAM, SATA II | DDR4/DDR5 RAM, NVMe, M.2 SSDs | | BIOS (Legacy) | UEFI, Secure Boot, TPM 2.0 | | Windows 7/8 | Windows 11, Server 2022, Linux basics | | IPv4 basics | IPv4 + IPv6, Subnetting, VLANs | | Basic routers | SD-WAN, Wi-Fi 6/6E, Cloud networking | | Copper cabling only | Fiber optics, SFP modules, structured cabling |

The core of hardware and networking education rests on understanding tangible components—motherboards, CPUs, routers, and switches—and the intangible protocols (TCP/IP, OSI layers, DNS) that animate them. Jetking’s traditional strength has been its ability to distill this complex interplay into digestible, exam-oriented notes. Yet, consider the rapid shift from copper cabling (Cat5e) to fiber optics and high-speed Ethernet standards (Cat6a, Cat8). An un-updated PDF might still describe obsolete IDE hard drives as primary storage, ignoring the dominance of NVMe SSDs. Similarly, in networking, the migration from IPv4 to IPv6, the rise of Software-Defined Networking (SDN), and the security demands of Zero Trust architectures are not just trends—they are current realities. Therefore, an updated PDF becomes a living document, ensuring that a learner studying for a Jetking certification understands 5G backhaul and Wi-Fi 6, not just legacy 802.11g. jetking notes of hardware and networking pdf updated
