What is a GPT partition, and how does it differ from MBR?
A GPT (GUID Partition Table) is a type of partition table that is used to define the layout of a hard drive or solid-state drive. It is a more modern and flexible alternative to the traditional MBR (Master Boot Record) partition table. GPT partitions are designed to work with UEFI firmware, which is a replacement for the traditional BIOS firmware found in older computers. One of the main advantages of GPT partitions is that they can support larger disk sizes and more partitions than MBR partitions.
In contrast to MBR partitions, which are limited to 2TB in size and can only have four primary partitions, GPT partitions can be much larger and can have up to 128 primary partitions. This makes GPT partitions a popular choice for modern computers and servers that require large storage capacities. Additionally, GPT partitions are more resistant to data corruption and can recover more easily from errors, making them a more reliable choice for critical systems.
