hard disk
The machine level.
Hardware are all the components that physically make up your computer; a keyboard, mouse, monitor, printer, and so on are all physical devices that you can touch and interact with. Software and data, in contrast, are logical and cannot be physically interacted with. While software is stored in a physical medium, it cannot be directly interacted with, because it only exists as a state within the hardware. Manipulation of software and data occurs through the physical interface, the hardware.
Any type of data.
A data field is a place where data can be stored. It may be a column in a database or a field in a data entry form.
Not possible, the same data can be stored both on floppy and HDD.

No, reformatting does not harm hardware. You just loose all your stored data.
Hardware is anything you can actually touch. Something you can kick when it makes you angry!The computer itself, keyboard, mouse, webcam, printer... Software is the programs, the data, the things you cannot see or touch physicaly...The stuff that's stored on the hardware! :D
Memory hardware that allows fast access to permanently stored data but prevents addition to or modification of the data.
The difference between software and hardware is that hardware is a physical object. Software is digital data stored on a physical [hardware] storage device. A motherboard is a circuit board, a physical object, and therefore hardware.
Hardware is the mechanical components of a computer including physical RAM chips, CPU, Motherboard, disc drives.Software is the program material, stored on and used by the computer as instructions and data. Generally it can be copied, transferred and manipulated easily.Firmware is software that has been permanently stored on a computer memory chip. Generally the only way of transferring this data, is by moving the chip it is stored on. So you can 'plug in' new data.
Depending on the context, those could be referred to as hardware or firmware.
I think you maybe thinking about the RAM ( random access memory).
The lowest data model is the physical data model. It represents how data is stored on a specific type of hardware and helps optimize storage and retrieval. It is the closest to the physical implementation in a database system.
The machine level.
stored data is data that gets placed in different places on a computer but there is different types of stored data
