Please learn people the correct things. 1 KB = 10^3 bytes = 1000 bytes. Kilo stands for 1000. 1 KiB = 2^10 bytes = 1024 bytes. KB stands for KiliByte, KiB stands for KibiByte. This goes on for MegaByte (10^6 bytes), GigaByte (10^9 bytes), TeraByte (10^12 bytes) etc. and MebiByte (2^20 bytes), GibyByte (2^30 bytes), TebiByte (2^40 bytes).
Guttural speech sounds are those with a primary place of articulation near the back of the oral cavity. In some definitions, this is restricted to pharyngeal consonants, but in others includes some velar and uvular consonants. Guttural sounds are typically consonants, but some vowels ' articulations may also be considered guttural in nature.
Evaluation of lung sounds is a routine part of a clinical examination. Breath sounds can be classified into 2 broad categories: normal breath sounds and adventitious (or abnormal) sounds. Adventitious breath sounds include wheezes, coarse crackles, fine crackles, and rhonchi. See the video of breath sound assessment, below.
