Certified - The CompTIA A+ 1201-1202 | V15 Audio Course

This episode covers the cable types and connectors that technicians are expected to recognize quickly on the A+ exam and in support work. You will compare copper and fiber network media, common video cables and adapters, and peripheral connections used for displays, storage, input devices, and other external hardware. The episode explains not just what these cables are called, but what they carry,...

This episode explains the display concepts that A+ candidates need in order to interpret user complaints and connect them to likely causes. You will review panel types, digitizers, brightness, contrast, resolution, refresh rate, touch behavior, dead pixels, burn-in, color issues, and the difference between a visual problem that comes from the panel itself and one that comes from a cable, setting,...

This episode focuses on the common network tools named in the A+ objectives and explains what each one helps a technician prove or rule out. You will learn how crimpers are used to terminate cable ends, how cable testers confirm continuity and pinout, how loopback plugs help verify that a port can send and receive correctly, and how taps support traffic visibility in more advanced situations. The...

This episode helps you sort through broadband and network-type terms in a way that makes them easier to remember and easier to apply on the A+ exam. You will compare common internet access methods such as cable, DSL, fiber, cellular, satellite, and fixed wireless, along with network categories such as LAN, WAN, PAN, WLAN, and SAN. Instead of treating these as isolated definitions, the episode expl...

This episode covers how a small office or home office network is put together in a way that supports everyday work without creating needless support problems. For the A+ exam, you need to understand how wired links, wireless access, internet connectivity, and remote access all fit together, including the role of switches, routers, access points, SSIDs, guest networks, and secure remote entry metho...

This episode explains the addressing concepts that A+ candidates must understand to configure devices correctly and recognize why a network path is failing. You will review the purpose of IPv4 and IPv6 addresses, subnet masks and prefix lengths, default gateways, DNS settings, private addressing, loopback, APIPA behavior, and the basic logic behind small office and home office network design. The...

This episode explains the major network devices technicians see in homes, offices, and small business environments, with emphasis on what each device does and where it sits in the path of communication. For A+ exam success, you need to distinguish a router from a switch, an access point from a modem, and a firewall from the devices that simply pass or extend traffic. The episode uses simple suppor...

This episode ties together four services that make networks usable, manageable, and secure, and it explains why the A+ exam expects you to know both what they do and what happens when they fail. You will review how DNS records connect names to services, how DHCP leases and reservations assign addresses, how VLANs separate traffic for control and security, and how VPNs create protected remote acces...

This episode explains the networked systems technicians are expected to recognize even when they are not the people building or administering them in depth. For the A+ exam, it is important to know what common server roles do, including file, print, web, mail, DNS, and DHCP services, because identifying the role of a system helps you understand what users lose when it fails. The episode also cover...

This episode covers the wireless topics A+ candidates need to understand without getting lost in unnecessary detail. You will compare how 2.4 GHz and 5 GHz Wi-Fi behave in terms of range, speed, and congestion, why channel overlap and interference affect user experience, and how wireless standards shape compatibility and expected performance. The episode also introduces short-range radio technolog...

This episode explains one of the most important networking comparisons in the A+ objectives by showing how TCP and UDP differ in behavior and why that difference matters when users report slow, broken, or inconsistent service. TCP is connection-oriented and emphasizes reliable delivery, sequencing, and retransmission, which makes it a good fit for web sessions, file transfers, and other tasks wher...

This episode builds the port and protocol recognition skills that help A+ candidates answer exam questions faster and troubleshoot real systems more logically. Instead of memorizing numbers without meaning, you will connect major ports and protocols to the services they support, such as web traffic, name resolution, remote access, file transfer, email delivery, and address assignment. The episode...

This episode explains the business-focused mobile support topics that often confuse newer technicians, especially when the device works but policy, permissions, or account settings block the user from doing what they need. For the A+ exam, you need to understand how location services affect mapping, tracking, and app behavior, how mobile device management enforces settings and restrictions, and ho...

This episode focuses on the mobile connectivity settings technicians must understand for the A+ exam and for everyday support work. You will learn how cellular service, Wi-Fi, and Bluetooth each behave differently, why airplane mode can disable multiple radios at once, and how to separate weak signal problems from bad settings, failed authentication, or interference. The episode explains practical...

This episode covers the mobile accessories and connection methods that appear in A+ support scenarios, with a focus on why the right accessory solves a problem and the wrong one creates a new one. You will review docks, port replicators, adapters, styluses, headsets, hotspots, and tethering, along with the practical limits of USB-C, Lightning, Bluetooth, and Wi-Fi based connections. For the exam,...

This episode explains how A+ candidates should think through common mobile hardware failures before opening a device or ordering a part. The exam expects you to connect symptoms to likely components, so you should know when a cracked display is only a glass problem and when the digitizer or full screen assembly is also affected, when fast battery drain points to battery wear instead of a charger i...
