ENERGY STAR certified heat pumps have higher ratings for seasonal energy efficiency ratio (SEER), energy efficiency ratio (EER), and heating seasonal performance factor (HSPF) and use about 5% percent less energy than conventional new models.
1 8 bits that contain the Type of Service, also referred to as Quality of Service (QoS), which describes what priority the packet should have, 2  16 bits that contain the length of the packet in bytes, 3  16 bits that contain an identification tag to help reconstruct the packet from several fragments, 4  3 bits.
Also note that there are only 128 ASCII characters. This means only 7 bits are required to represent an ASCII character. However, since the smallest size representation on most computers is a byte, a byte is used to store an ASCII character. The MSb of an ASCII character is 0.
