The speed or rate which can be transferred from one place to another place. They are measured in bits pr second, mbps or kbps. Whilst the bitrate increases the sound quality may boost.
For Example, MP3 files having a bitrate of 128KBPS are far more prone to sound than a MP3 file having a bitrate of 64KBPS. The 128KBPS MP3 file will be greater in dimensions.
In digital communication systems, the physical layer gross bitrate, raw bitrate, data signaling rate, gross data transfer rate or uncoded transmission rate (sometimes written as a variable Rbor fb is the total number of physically transferred bits per second over a communication link, including useful data.

The hard disk was invented on September 13, 1956 by IBM team led by Rey Johnson (considered as “father” of the disk drive). Earlier hard disk drives were large and cumbersome devices.
