​KembaraXtra-Computer Terms – bit density:
Bit density is a measurement that describes how much digital information can be stored or transmitted within a given space or time. In storage devices, it refers to the number of bits that can be recorded along a specific length or across a surface area of the storage medium.
In communication systems, bit density may also describe the number of bits transmitted during a particular time interval within a communication channel. Higher bit density generally indicates greater storage capacity or faster information transfer capability.
