==Enable/disable built-in perpherals==
Linux provides several commands to manage kernel modules, which control hardware devices:
*modprobe: Intelligently adds or removes modules from the kernel
*insmod: Inserts a module into the kernel
*rmmod: Removes a module from the kernel
*lsmod: Lists currently loaded kernel modules

==Differences between mas storage devices==
These tools allow administrators to dynamically enable or disable hardware components without rebooting the system.
*HDD (Hard Disk Drive):
**Uses magnetic storage
**Slower than SSDs
**More affordable per GB

*SSD (Solid State Drive):
**Uses flash memory
**Significantly faster than HDDs
**More expensive per GB
**Lower power consumption

==More durable due to lack of moving parts==
*Optical storage:
**Uses laser to read/write data
**/Slower than both HDDs and SSDs
**Primarily used for removable media (CDs, DVDs, Blu-ray)

==Linux provides several methods to gather hardware information==
*lsusb: Lists USB devices
*lspci: Lists PCI devices
*/sys/: A virtual filesystem providing detailed hardware information
*/proc/: Another virtual filesystem with system and hardware data
*/dev/: Contains device files for interacting with hardware

==The primary tool for USB device management is lsusb, which==
*Lists all USB devices connected to the system
*Provides detailed information about USB devices
*Can be used with various options for more specific data

== Understanding sysfs, ydev, and dbus
*sysfs:
**A virtual filesystem mounted at /sys
**Exports kernel device information to userspace
**Provides a hierarchical view of system devices
*udev:
**The device manager for the Linux kernel
**Creates/removes device nodes in /dev dynamically
**Uses rules to name devices and set permissions
**Monitors sysfs for device changes
*dbus:
**A message bus system for inter-process communication
**Allows applications to communicate with each other
**Used by desktop environments for hardware-related events
