Booting process is the sequence of events that occur when a computer is turned on and starts up.

• Power on self-test (POST) is performed to check hardware components

• BIOS or UEFI firmware is loaded to initialize hardware

• Boot loader is loaded to start the operating system

• Operating system kernel is loaded into memory

• User login prompt is displayed

Common causes for boot failure include hardware issues, software errors, and incorrect BIOS settings.

• Hardware failure (e.g. faulty hard drive, RAM issues)

• Software errors (e.g. corrupted operating system files)

• Incorrect BIOS settings (e.g. boot order misconfiguration)

LVM stands for Logical Volume Manager, a tool used in Linux to manage storage by creating logical volumes from physical volumes.

• LVM allows for dynamic resizing of logical volumes without disrupting data.

• It provides features like snapshots, striping, mirroring, and thin provisioning.

• Common LVM commands include pvcreate, vgcreate, lvcreate, lvextend, and lvresize.

To create an LVM, you need to initialize physical volumes, create a volume group, and then create logical volumes within the volume group.

• Initialize physical volumes using pvcreate command

• Create a volume group using vgcreate command

• Create logical volumes within the volume group using lvcreate command

yum command is used to install, update, remove, or manage packages on Linux systems.

• Install a package: yum install package_name

• Update all packages: yum update

• Remove a package: yum remove package_name

• List available packages: yum list available
