1. What is a file system?
Answer: The file system is the method and data structure used by the operating system to identify files on a disk or partition.
2. What is the difference between MBR partition and GPT partition?
Answer: 1. The MBR partition table can only identify the space of about bai2TB at most, and the capacity larger than 2TB will not be recognized, resulting in a waste of hard disk space; the GPT partition table can identify the hard disk space above 2TB.
2. The MBR partition table can only support up to 4 primary partitions or three primary partitions + 1 extended partition (there is no limit to logical partitions); the GPT partition table can support 128 primary partitions under the Windows system.
3. In MBR, the size of the partition table is fixed; the maximum number of partitions can be customized in the GPT partition table header, which means that the size of the GPT partition table is not fixed.
3. What is the purpose of initializing a disk?
Answer: Import or activate the hard disk
4. What are the volumes of Windows dynamic disks?
Answer: Simple volume, spanned volume, striped volume, mirrored volume, raid-5 volume
5. What are the similarities and differences between spanned and striped volumes?
Answer: Spanned volume: A spanned volume is a dynamic volume composed of multiple physical disk spaces. The difference is that at least two disk
striped volumes are required: creating a striped volume also requires at least two disks. The volume is different, the amount of disk space provided by each hard disk must be the same,
6. . What are the operations for managing volumes?
Answer: Expand volume, compress volume, add mirror, delete mirror, interrupt, mirror volume, delete volume
7. Briefly describe the role and characteristics of RAID-5 volumes
Answer: When using a raid-5 volume, in addition to the data being scattered and written to each hard disk, a parity verification data message will also be created at the same time, which is stored on different hard disks. If one hard disk fails, the remaining Calculate the original data on the hard disk combined with the validation information. Raid-5 volumes have higher disk utilization and read-write performance than mirrored volumes, and higher data reliability than striped volumes.
8. What is the difference between interrupting mirroring and deleting mirroring? .
Answer: Interrupting the mirrored volume will make the mirrored volume into two simple volumes.
Deleting a mirror can delete a mirror in a mirrored volume and use its space for other purposes.
9. What are the options for selection in the format window?
Answer: NTFS refs fat32
10. Use the table to compare the names, number of disks, capacity calculation methods, scalability, and fault tolerance of the five Windows dynamic volumes
Answer:
Name of the number of disks, capacity calculation method, expandable attributes, fault tolerance,
simple volume, one piece is OK, both
spanned volume two or more spanned volume capacity is the sum of all the disk space composing the spanned volume, the maximum expandable To create a spanned volume with 32 dynamic disks, in addition to the boot disk, at least two dynamic disks are required.
Striped volume The data on two or more striped volumes is evenly distributed across disks in a striped form. The use of multiple contiguous disk spaces that form a spanned volume is uniformly allocated by the file system. A dynamic volume that stores data on two or more physical disks in striped form
