The measure of how quickly information can be transmitted between devices or across networks, typically expressed in bits or bytes per second.

Data Transfer Rates

Data transfer rates, also known as bandwidth in digital communications, represent the speed at which information moves from one point to another in a computing or telecommunications system.

Fundamental Concepts

The measurement of data transfer rates typically follows these conventions:

Bits per second (bps) - The most basic unit
Bytes per second (B/s) - Groups of 8 bits
Common prefixes:
- Kilo (K) = 1,000
- Mega (M) = 1,000,000
- Giga (G) = 1,000,000,000
