2.1.3 Addressing and byte Ordering

• These procedures use the C sizeof operator to determine the number of bytes used by the object. In general, the expression sizeof(T ) returns the number of bytes required to store an object of type T . Using sizeof rather than a fixed value is one step toward writing code that is portable across different machine types.

2.1.6 Introductino to Boolean Algebra

• Since binary values are at the core of how computers encode, store, and manipu- late information, a rich body of mathematical knowledge has evolved around the study of the values 0 and 1.
