No. You never need to know how to interpret the bits in each byte; you cannot address individual bits. Endianness refers to how different bytes within a multi-byte value are addressed; little endian means that the smaller addresses refer to the lower order bytes, big endian mean that smaller addresses refer to the higher order bytes. Think of it as which order you write the digits in a number. Each digit (byte) means the same thing regardless of whether you are big-endian or little-endian. But in big endian, you would write one thousand two hundred thirty four as 1234, while in little endian you would write it 4321.
