1.A dual boot system is a computer system in which two operating systems are installed on the same hard drive, allowing either operating system to be loaded and given control.
2.The swept area refers to the area of the circle created by the blades as they sweep through the air.
3.A mount point is a directory in a file system where additional information is logically connected from a storage location outside the operating system's root drive and partition.
4.In a computer, a file system -- sometimes written filesystem -- is the way in which files are named and where they are placed logically for storage and retrieval.
5.The ext4 journaling file system or fourth extended filesystem is a journaling file system for Linux, developed as the successor to ext3.
6.There are two basic types of disks in the computer hardware realm: magnetic disks and optical disks.
7.Basic disks are the storage types most often used with Windows
8.Dynamic disks are a separate form of volume management that allows volumes to have noncontiguous extents on one or more physical disks.

10.Ubuntu will see only one big partition and is not able to see how this big partition is split into several dynamic partitions, as this is a totally Windows-internal thing. It is not possible to install Ubuntu in such a dynamic partition.
we will have to convert the dynamic partitions back to basic partitions and surely we will have to delete the newly created partition first, otherwise the conversion would probably fail.

11.There are three types of brick partition walls which include plain brick partition wall, reinforced brick partition wall, and brick nogging partition wall.
12.the MBR is a special boot sector located at the beginning of a drive. This sector contains a boot loader for the installed operating system and information about the drive’s logical partitions.

13.The format used to define the hard disk partitions in computers with UEFI startup firmware. The GUID Partition Table (GPT) replaces the previous master boot record (MBR) method.

15.There are two different types of BIOS: UEFI (Unified Extensible Firmware Interface) BIOS - Any modern PC has a UEFI BIOS. UEFI can handle drives that are 2.2TB or larger thanks to it ditching the Master Boot Record (MBR) method in favor of the more modern GUID Partition Table (GPT) technique.
16.The Unified Extensible Firmware Interface (UEFI) is a specification that defines a software interface between an operating system and platform firmware. ... UEFI can support remote diagnostics and repair of computers,
17.In computing, legacy mode is a state in which a computer system, component, or software application behaves in a way that is different from its standard operation in order to support older software, data, or expected behavior.
18.UEFI
19.The main difference between UEFI and legacy boot is that the UEFI is the latest method of booting a computer that is designed to replace BIOS while the legacy boot is the process of booting the computer using BIOS firmware. ... Legacy boot is the regular method of booting the system using BIOS.
20.Ubuntu releases are supported for 18 months. Ubuntu LTS (Long Term Support) releases are supported for 3 years on the desktop, and 5 years on the server.
