It is a matter of word choice. BC stands for bouyancy compensator, while BCD stands for bouyancy compensator device. They are the same thing, just under slightly different names. They are further broken into three catagories: jacket/vest, back flotation, and horse collar. The latter is rarer in modern diving gear (think of Jaqcques Cousteau), but can still be seen on a few divers, especially those that do a lot of skin diving. Hope this helps. BC was first brought into official used by SSI (Scuba Schools International) in their open water course (which was the first course in scuba to be offered to the public ) and then later, PADI changed it to BCD - basically, to be different. Adding onto what was said above, i have never heard of buoyancy compensator device, but instead buoyancy control device. Buoyancy control device, i think, is more sensible as as saying that something compensates your buoyancy doesn't really make sense.

What is the difference between 110 BCD and 130 BCD in bicycle chainring sizes?
The main difference between 110 BCD and 130 BCD in bicycle chainring sizes is the bolt circle diameter (BCD). 110 BCD means the chainring has a bolt circle diameter of 110 millimeters, while 130 BCD means the chainring has a bolt circle diameter of 130 millimeters. This difference affects the number and placement of bolts used to attach the chainring to the crankset, as well as the overall size and tooth count of the chainring.
What is the LCM of bc and cd?

What are the differences between 110 BCD and 130 BCD chainrings in terms of compatibility and performance?
The main difference between 110 BCD and 130 BCD chainrings is the bolt circle diameter (BCD), which affects compatibility with cranksets. 110 BCD chainrings are typically used with compact cranksets, while 130 BCD chainrings are used with standard cranksets. The choice between the two can impact gear ratios and overall performance on the bike.
What is the difference between a BCD to decimal decoder and a BCD to 7-segment decoder?
A: A BCD code must be decoded to provide a seven digit output to the 7 bars display that is the only way to see the binary number visually.
What is the difference between binary codes and bcd codes?
In BCD each digit of a decimal number is coded as a separate 4 bit binary number between 0 and 9.For example:Decimal 12 in BCD is shown as 0001 0010 (Binary 1 and Binary 2), in Binary it is 1100.
What is the difference between BC-B and BC-D castes?
In the Indian caste system, BC-B and BC-D are subcategories within the Backward Class (BC) category. The main difference lies in the specific communities or groups they represent. BC-B typically includes different communities from BC-D, with each group having its own distinct characteristics, history, and social standing within the caste hierarchy. These distinctions are important for understanding the diverse social structure and dynamics of the Indian caste system.
