We explain how improper handling can damage sensitive components like CPUs, RAM, and storage devices even before they’re install...

This episode focuses on the backup strategies and data recovery techniques that every IT professional must know. We begin with the Grandfather-Father-Son (GFS) backup rotation model, explaining how it balances data redundancy and storage space. Then we dive into the 3-2-1 rule—keeping three copies of your data, on two different media types, with one copy off-site. We also explore full, incremental...

Change is a constant in IT, but managing that change responsibly is what keeps systems stable. This episode introduces the formal change management process, starting with the identification of proposed changes and their potential impact on systems, users, and business operations. You’ll learn about documentation requirements, stakeholder approvals, and the importance of scheduling changes during m...

There’s more than one kind of documentation in I T, and this episode explains the major types that appear on the A Plus exam. We start with Acceptable Use Policies (AUPs), which define what users are permitted to do with company devices and networks. These documents are key to setting boundaries and providing grounds for enforcement. Next, we cover Standard Operating Procedures (SOPs), which descr...

Keeping track of hardware, software, and configuration data is vital for organizations of all sizes, and this episode explores how asset and inventory management supports that effort. We begin with physical asset tracking—using labels, barcodes, and location databases to monitor laptops, desktops, and peripherals. Then we move into software inventory, including how to track licenses, subscription...

This episode focuses on the importance of clear, consistent documentation in every phase of IT support. We begin by explaining ticketing systems—how they track user requests, service histories, resolutions, and follow-up actions. You’ll learn what makes a good ticket entry, including timestamps, concise descriptions, and links to previous cases. We also cover other forms of documentation, such as...

The final domain in the Core 2 exam is Operational Procedures, and this episode introduces its wide-ranging content. You’ll learn what this domain includes: documentation standards, safety procedures, communication skills, licensing and privacy concerns, and basic scripting. While these topics may seem non-technical, they are just as important for a well-rounded technician as knowing how to fix ha...

Malware isn’t limited to desktops. In this episode, we explore the types of malicious threats that target mobile devices. We begin with adware, spyware, and malicious apps that gain access to sensitive permissions—like camera, microphone, or SMS—without the user’s knowledge. Then we explain the concept of rooting or jailbreaking, which removes manufacturer restrictions and increases exposure to se...

Mobile devices introduce their own unique troubleshooting challenges, particularly when it comes to application behavior. In this episode, we start with app crashes—why they happen, how to review logs or force close misbehaving apps, and what steps to take before uninstalling. Then we examine connectivity issues within apps, such as those that rely on Wi-Fi or cellular data and behave erratically...

Successfully removing malware requires following the right sequence, and this episode lays out that process according to CompTIA’s expectations. We begin with identification—recognizing that malware is present—followed by isolating the system from the network to prevent spread. Then we quarantine the malicious files using antimalware software and proceed with cleaning or deleting the infections. W...

Security issues don’t always come with flashing warnings—sometimes they hide behind subtle behavior. This episode helps you identify the symptoms that often indicate malware or unauthorized access. We begin with security alerts—both real and fake—and how to distinguish between legitimate warnings and scareware popups. Then we cover unexplained file changes, such as altered timestamps, missing data...

When something breaks in Windows, there are several tools you can use to restore functionality, and this episode breaks them down step by step. We begin with the System File Checker (SFC), which scans and repairs corrupted or missing system files using known-good versions. Next, we explain DISM and when to use it alongside or instead of SFC to fix more deeply embedded issues. We also discuss more...

This episode covers some of the most common and dramatic symptoms you'll face when troubleshooting Windows systems. We begin with the infamous Blue Screen of Death—also known as BSOD—explaining what causes it, how to interpret error codes, and what logs or tools to use when diagnosing the issue.
