Linux Disk Management Tools

Background info

The old standard for managing disk partitions was via the Master Boot Record (MBR). This was replaced by GUID Partition Table (GPT). This is more flexible, more resilient, allows larger partition sizes, and is used with UEFI systems. Tools like fdisk used to only support MBR, which made parted more useful for GPT support, but fdisk now also supports GPT.

Hypervisors

A type 1 hypervisor provides virtualisation on a bare metal server. Type 2 runs within an OS. Type 1 hypervisors are more efficient and performant, but offer less flexibility. Also, type 1 hypervisors offer better security since OS vulnerabilies are limited to each virtual instance rather than the hypervisor OS, which could compromise all the hosted OSes at once.
