bit

bit by bit : by small steps or amounts : gradually <Bit by bit, the truth came out.

However, in contrast to turbo codes, which use just two decoders, LDPC codes use a separate decoder for each bit of the message, creating a giant rumor mill.

The AES is capable of using cryptographic keys of 128 bit, 192 bit, and 256 bit to encrypt and decrypt data in blocks of 128 bits.

The first flag is the existing "D" bit that controls the size of operands.

This benefit becomes patently obvious when processing very large problems that don't fit in the 4-GB limitation that 32 bits puts on system memory.
