What is the difference between GPT partition and MBR partition of hard disk?

The difference between hard disk partition format and mbr format is that MBR means "master boot record" and GPT means GUID partition table.

"gpt format" has brought many new features, and it can support the large capacity of 18EB at most (1EB= 1024 PB, 1PB= 1024 TB).

"mbr format" only supports 2TB at most, but it has the best compatibility.

The role of hard disk:

Hard disk is the main storage medium of computer, which is equivalent to the warehouse of computer. Operating system, installed software, documents and materials are all stored in the "warehouse" in the form of data (0 and 1).

The operation of the software is to first transfer the data into the memory, the CPU interacts with the memory, and the final result is put into the external memory, that is, the hard disk. Therefore, hard disk is one of the important hardware that computers should not divide.

Hard disk is one of the main storage media of computer, which is composed of one or more disks made of aluminum or glass. The disk is covered with ferromagnetic material.
