In the world of live streaming, bandwidth refers to the rate of data transfer your computer and other devices have access to, measured in bits per second. Because bits are such a small unit of data, bandwidth speeds are usually referred to with the prefixes like kilo, mega, or giga. Kilo means thousand, mega means million, and giga means billion. So, for example 1 kilobit is the same as 1 thousand bits, 1 megabit is 1 million bits and 1 gigabit is 1 billion bits.
These same prefixes also apply to bytes. It is important to understand, however, that bits and bytes are NOT the same. A bit is the smallest unit of computer information, representing either a 1 or a 0. A byte is 8 bits. Data transfer speeds are usually represented in bits per second, and data storage is usually measured in bytes.
