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.
8 bits are known as a byte, and it is bytes which are used to pass our information in it's basic form - characters. An alphanumeric character (e.g. a letter or number such as 'A', 'B' or '7') is stored as 1 byte. For example, to store the letter 'R' uses 1 byte, which is stored by the computer as 8 bits, '01010010'. A document containing 100 characters would use 100 bytes (800 bits) - assuming the file didn't have any overhead (additional data about the file which forms part of the file).
