The term 'Tiny Storage Unit' can be summarized as a four-letter word, 'byte'. A byte is a unit of digital information that typically consists of eight bits. It is the smallest addressable unit of memory in a computer and is used to store a single character. Bytes are often used to measure file sizes, such as the size of an image or a text document. They are also used to measure data transfer speeds, such as the speed of an internet connection.
