IT Support Foundations

What you will be able to do

• You will be able to describe what an IT Support Specialist does day to day, including support tiers (L1 to L3), escalation paths, and how SLAs set the clock on every ticket.
• You will be able to tell an incident apart from a service request and route each one the way an ITIL-based service desk does.
• You will be able to identify the core hardware components inside a computer (CPU, RAM, storage, motherboard, power supply, and peripherals) and explain what each one does.
• You will be able to trace the software stack from firmware and BIOS or UEFI up through drivers, the operating system, and applications, and reason about where a problem actually lives.
• You will be able to perform everyday tasks across Windows, macOS, and Linux, including managing user accounts, permissions, files, and installed software.
• You will be able to apply a repeatable troubleshooting method (reproduce, isolate, test, verify, and document) to any support problem instead of guessing.
• You will be able to work a ticket from first contact to close, setting priority and severity, meeting the SLA, documenting your steps, and escalating cleanly when needed.
• You will be able to communicate with users professionally under pressure, set clear expectations, show empathy, and de-escalate a frustrated customer.

What is inside

4 modules, 8 lessons. Each module ends in a graded quiz and most carry an assignment.

1. 01

   The Help Desk Role and How IT Support Works

   Start with the job itself. This module explains what an IT Support Specialist does all day, who you support, and how support tiers, escalation, and SLAs move a ticket to the right person on time. You will learn the distinction every service desk runs on, an incident (something is broken) versus a service request (someone needs something), and why ITIL frames the work this way. By the end you will hold the core vocabulary and mental model that the rest of the course builds on.

2. 02

   Computer Hardware and Software Basics

   This module opens up the computer so you can reason about problems instead of guessing at them. You will learn what each core hardware component contributes (CPU, RAM, storage, motherboard, power supply, and peripherals) and how the software stack layers from firmware and BIOS or UEFI up through drivers, the operating system, and the applications users see, so you can tell which layer a fault lives in.

3. 03

   Operating Systems and Everyday Troubleshooting

   Get comfortable on any machine that lands on your desk. This module works across Windows, macOS, and Linux to manage user accounts, permissions, files, and installed software, the everyday tasks that fill a real support queue. Then it gives you one repeatable troubleshooting method you can run on any ticket: reproduce the problem, isolate the cause, test a fix, verify it, and document what you did.

   The Ticketing Workflow and Customer Service

   Walk a ticket from first contact to close (logging it clearly, setting priority and severity, meeting the SLA, documenting the work, and escalating cleanly), and pair it with the customer service skills that make or break the role: plain-language communication, empathy, expectation-setting, and de-escalation.
