MBR and GPT

MRB for Win platform
GPT is used primarily for Mac (Apple),
The relationship between MBR partition table and GPT partition table

GPT disk partitioning style supports a maximum volume of 18 compared to the style of MBR disk partitioning that supports a maximum volume of 2 TB (terabytes) and a maximum of 4 primary partitions per disk (or 3 primary partitions, one extended partition and unlimited logical drives) EB (exabytes) and there is no upper limit on the number of partitions per disk, only limited by the operating system (because the partition table itself needs to occupy a certain amount of space, initially planning the hard disk partition, the space left to the partition table determines the maximum number of partitions, the IA-64 version of Windows limited to a maximum of 128 partitions, This is also the minimum size of the partition table as specified by the EFI standard). Unlike MBR partitioned disks, critical platform operational data is located in partitions, not in non-partitioned or hidden sectors. In addition, the GPT partition disk has a backup partition table to improve the integrity of the partitioned data structure.
