All data in computers based on digital electronics is represented as bits (alternatives 0 and 1) on the lowest level. The smallest addressable unit of data is usually a group of bits called a byte (usually an octet, which is 8 bits). The unit processed by machine code instructions is called a word (as of 2011 , typically 32 or 64 bits). Machine data types expose or make available fine-grained control over hardware, but this can a… WebDatabase data types refer to the format of data storage that can hold a distinct type or range of values.
