Open the course pathThese lessons and checks are currently available as preview study material. Each block names its required provider or ITForMe lesson; optional provider products may have their own costs.
How you will study
- Study one learning block. Use its assigned provider lesson when one has been verified. Where no suitable assignment has been verified, study the required ITForMe teaching. Other explanations and guided practice remain available for support.
- Confirm study and take its short check. Opening a page or provider link does not complete a block. A passing current check is required for course progress.
- Review and continue. Today suggests the next activity using your study and review history. Review helps you revisit earlier concepts while you learn new material.
Connect the command you run to the file, process, service, permission, or kernel state it changes.
Basic Linux concepts
This is a short excerpt of ITForMe concept notes. It shows the kind of explanation available here; it is not the complete lesson or a scored check.
- Kernel
- Runs in privileged mode to schedule CPU time, manage memory and devices, and expose system calls to user-space processes.
- Initial RAM filesystem
- Provides a temporary filesystem held in memory during boot so its drivers and scripts can locate and mount the real root filesystem.
- Bootloader
- Loads a selected kernel and passes its startup parameters.
- Filesystem Hierarchy Standard
- Defines conventional purposes for major Linux directory paths.
Applied practice: Use a disposable Linux system. Predict a command's effect, run it, inspect exit status and logs, then restore the starting state.
