The difference between Bps (bytes per second) and bps (bits per second) primarily lies in the unit of measurement for data transfer rates.

**bps (bits per second)**: This is a measure of how many bits (the smallest unit of data in computing, which can be a 0 or a 1) are transferred each second. It’s commonly used to describe the speed of internet connections and other data transmission rates across networks. For example, internet speeds might be advertised as Mbps (megabits per second) or Gbps (gigabits per second).**Bps (bytes per second)**: A byte is equal to 8 bits. Therefore, bytes per second measures the number of bytes that are transmitted each second. This unit is more common when referring to file transfer speeds within a computer system, such as when moving files from one part of a storage drive to another or when measuring storage device speeds (e.g., SSDs or HDDs).

**Conversion**:

- 1 Byte per second = 8 bits per second. Thus, if you are converting from Bps to bps, you multiply the number of bytes per second by 8 to get the number of bits per second. Conversely, to convert from bps to Bps, you divide the number of bits per second by 8.

**Practical Example**:

- If you have an internet connection speed of 100 Mbps, you are effectively getting a maximum download speed of about 12.5 MBps (100 Mbps / 8 = 12.5 MBps).

Understanding this distinction is essential for accurately interpreting what kinds of speeds you can expect in different scenarios, such as downloading files versus streaming content online.
