Does memory address always refer to one byte, not one bit?

Question

1. Can you confirm that memory address in a PC is alway pointing to one byte (8 bits)?
2. If a float number needs 32 bits in memory, does the computer allocate 4-sequential bytes (32 bits total) to represent that number?

Answer 1

1. Yes, a memory address always contains a byte address. I can't think of a single CPU architecture that supports bit-level addressing.

2. A CPU native float will always be stored in sequential memory locations. This is true for all native CPU types.
