Explanation & Hint:
- “It is a section of an extended partition on an MBR. It can be used to separate information for administrative purposes.” This statement accurately describes a logical drive. In the context of an MBR (Master Boot Record) partitioned disk, you can have a maximum of four primary partitions. However, to overcome this limitation, one of these can be made into an extended partition. This extended partition can then be subdivided into multiple logical drives. Logical drives are not physical partitions themselves but are ways to segment and manage data within an extended partition. They are often used for organizing and managing data separately from the operating system and other primary partitions.
- “It takes the first 512 bytes on the disk and contains the boot loader, an executable program that allows a user to choose from multiple operating systems.” This describes the Master Boot Record (MBR) itself, not a logical drive. The MBR is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives. It contains information about how the logical partitions, containing file systems, are organized on that medium. The MBR also includes a boot loader, which is a small program that loads the operating system.
- “It is a standard for the layout of the hard drive partition table using globally unique identifiers. All partitions are primary.” This statement refers to the GUID Partition Table (GPT). GPT is a modern standard for the layout of the partition table on a physical storage device used in a desktop or server PC, such as a hard disk drive or solid-state drive. Unlike MBR partitioned disks, GPT does not have a limitation on the number of partitions, and all partitions are considered primary, eliminating the need for extended partitions and logical drives.
- “It is a physical section of a hard disk. It can contain an operating system to boot the system and cannot be subdivided.” This is a description of a primary partition. Primary partitions are physical portions of a hard disk drive. They can be used to boot an operating system and are limited in number (up to four per disk in MBR). Unlike logical drives within an extended partition, primary partitions cannot be subdivided into smaller segments within the same partitioning scheme.
In summary, the statement that best describes a logical drive is the first one, which mentions it being a section of an extended partition on an MBR disk, used for administrative purposes. |
