storage, compression and size vs quality

 storage 

storage is described as the recording of information in a storage medium.

flash drive - A flash drive is a electronic device that contains flash memory which is used to store data or transfer it to or from a computer.

hard drive -  An electro-mechanical data storage device which stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.

solid state drive -  a solid- state storage device that uses integrated circuit assemblies to store data persistently.

cloud- the on-demand availability of computer system , especially data storage and computing power without direct active management by the user.

compression

DRC- Dynamic range compression balances the range between the loudest and quietist sounds and this function can be used to enjoy Dolby digital sound when watching movies at low volume.

Downward compression- reduces the volume of loud sounds above a certain threshold. 

upward compression- A type of dynamic range compression which boosts the amplitude of an audio signal below a certain threshold while maintaining the amplitude above the threshold.

size versus quality

lossy- the data in a file is removed and not restored to its original form after decompression.

lossless- a class of data compression which allows the original data to be perfectly reconstructed from the compressed data with no loss of information.

file size - the measure of space a file takes up on a storage medium.

bit rates - bit rates are the number of bits per second and generally determines the size and quality of video and audio files.
