In the analog transmission of information of the physical size, the corresponding data are continuously impressed.
Each value is in a specified interval admissible and relevant at all times.
In the digital transmission of information in the physical size of the corresponding data are imparted discretely.
Here are several noncontiguous areas intervals allowed that are only in certain not directly successive time intervals relevant.
The data transfer rate (bit rate) is the amount of digital data that is moved from
one place to another in a second's time. It is the speed of travel given in "bps".
Baud - a unit of digital transmission signalling speed of information transmission.
It is used to describe the rate of information flow. Given in bits per second (bps) the rate
is the highest number of single information elements (bits) transferred between
two devices in one second - such as modems or fax machines.
