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.
Bits, Bytes, Nybbles. The most important base you need to know for computer organization is base 2. We also call this binary, since binary means two valued. The second most important base is base 16 (or hexadecimal), and the third is base 8 (octal). Beyond that, you don't need to know the other bases. Let's start with some definitions first. 1  bit A single binary digit, that can have either value 0 or 1.  byte 8 bits.
