101 System Architecture KA Flashcards
Knowledge Area
101.1 Determine and configure hardware settings
Key Knowledge Areas:
Enable and disable integrated peripherals.
Differentiate between the various types of mass storage devices.
Determine hardware resources for devices.
Tools and utilities to list various hardware information (e.g. lsusb, lspci, etc.).
Tools and utilities to manipulate USB devices.
Conceptual understanding of sysfs, udev and dbus.
Enable and disable integrated peripherals.
These devices are disabled in the BIOS stage, since this is a relatively simple task it will not be listed.
Differentiate between the various types of mass storage devices.
Here is a list of different mass storage devices in Linux.
sd* = SCSI device driver hd* = IDE device driver nvme0* = NVME device driver
