the unit is called decimal digit, hartley, ban, decit, or dit, and is equal to log 2 10 (≈ 3.322) bits. [2] [4] [5] [6] Base b = e, the base of natural logarithms the unit is called a nat, nit, or nepit (from Neperian), and is worth log 2 e (≈ 1.443) bits. [2] The trit, ban, and nat are rarely used to measure storage capacity; but the nat ...
Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium.There are three types of density: length (linear density) of track, area of the surface (areal density), or in a given volume (volumetric density).
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.

File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. [3]
This is called the transition width. Many hard drive platters have a layer of lubricant made of amorphous carbon such as diamond-like carbon, called an overcoat, which is deposited onto the disk using sputtering, or using chemical vapor deposition. [2] Silicon Nitride, PFPE [3] [4] and hydrogenated carbon have also been used as overcoats.
