DefinitionA byte (バイト) is a unit of information that handles 8 bits together as one group.
ExplanationOne byte is 8 bits, so it can tell apart 2 to the 8th, or 256, patterns. The capacity of files and storage devices is written by putting a prefix such as k, M, G or T in front of the byte.
AnalogyIt is like counting eggs by the eight-egg carton instead of one by one: say how many cartons there are and you know at once how many eggs are inside.
Memory hookByte is said to be a coined word playing on bite, so you can remember it as one "mouthful" of data.
