A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including brain cells. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. They are quickly turned into glucose in your body.
A binary variable is the same thing as a â bit â in computer science or a âtruth valueâ in mathematical logic. They are basically different names for the same thing, much like statisticians call a Bell curve a â Normal Distribution â and physicists call it a â Gaussian distribution .â.
One bit contains a single binary value â either a 0 or a 1. A byte contains eight bits, which means it can have 256 (28) different values. These values may be used to represent different characters in a text document, the RGB values of a pixel within an image file, or many other types of data. Large files may contain several thousand bytes (or several megabytes) of binary data.
