Task guide Check What Computer You Have
Use this when you need a calm first inventory of the computer in front of you.
Many beginner mistakes start with acting on the wrong machine assumptions. A safe inventory makes later decisions more realistic.

Goal
Build a safe first inventory of the computer before you do anything else.
Safe sequence
- identify the operating system and machine model
- identify the CPU
- identify the memory size
- write down what you found in plain words
Windows notes
- Use
Get-ComputerInfo, systeminfo, or system information views first.
- Keep the goal small: identity before action.
Linux notes
- Use
hostnamectl, lscpu, and free -h for a safe first pass.
- Stop after you can describe the machine clearly.
Move on when
- you can name the machine in plain language
- you can separate CPU, memory, and storage correctly
- you know the machine better than when you started
Before you start - Stay with read-only system information tools.
- Capture the model, CPU, and memory before searching for fixes.
- Do not guess based on the sticker or the screen size alone.
Verify with - You can name the machine model or family.
- You can identify the operating system.
- You can identify the CPU and memory size.
Avoid these mistakes - Do not install tools just to inspect the basics.
- Do not change firmware, drivers, or updates during this check.
- Do not confuse storage size with memory size.
Move on when - You can inspect the machine safely on Windows or Linux.
- You can identify the core specs without outside help.
- You can explain why the inventory came before troubleshooting.
Reflect before you leave - Which detail changed your understanding of the machine most?
- What assumption did this inspection correct?

Learn deeply M00A - What Is a Computer? Understand a computer as one whole system that takes input, processes work, stores data, and produces output.
M00B - Hardware, Software, and the Operating System Separate hardware, software, firmware, and the operating system so the computer stack stops feeling blurred together.
M00C - CPU, Memory, and Storage Understand the different jobs of the CPU, memory, and storage so hardware words stop collapsing into one vague idea.
