Frequently Asked Questions
How does Linux represent hardware devices?
Linux exposes devices through special files in /dev and information in sysfs, while udev dynamically manages device nodes and related events.
Which hardware inspection tools are included?
The course introduces lsusb, lspci, and lsscsi for identifying USB, PCI, and SCSI devices, along with common Linux device naming conventions.
Is the dd command safe to practice?
dd can overwrite disks when given the wrong destination. Review every input and output path and practice only with disposable files or devices you can safely replace.
