A disk is a hardware component that stores your data. It comes in various types and uses different interfaces. 
The main disk types are the well-known spinning HDD, the SSD, and the non-volatile memory express (NVMe). SSDs and NVMes use RAM-like technologies, with better energy consumption and higher transfer rates than original spinning hard drives. 

sudo fdisk -l

/proc/partitions

There are two major partition types – the Master Boot Record (MBR) and the GUID Partition Table (GPT).  
MBR was intensively used up to around 2010. Its limitations include the maximum number of primary partitions (four) and the maximum size of a partition (2 TB).

GPT became a part of the Unified Extensible Firmware Interface (UEFI) standard as a solution to some issues with MBR, including partition limitations, addressing methods, using only one copy of the partition table, and so on. 
It supports up to 128 partitions and disk sizes of up to 75.6 Zettabytes (ZB).

fdisk: A command-line partition editor, perhaps the most widely used one
Sfdisk: A non-interactive partition editor, used mostly in scripting
parted: The GNU (the recursive acronym for GNU is GNU's Not Unix) partition manipulation software
gparted: The graphical interface for parted
df (Disk Free) utility is a command-line tool that displays the disk space used and available in filesystems on Linux systems. 
du utility is another essential command-line tool that’s used in Linux systems to determine the amount of space used by specific directories and files.
