The term 'PART OF A GIG' can be broken down into three separate words: SET (3 letters), MEG (3 letters), and BYTE (4 letters). SET is an acronym for a Small Electronic Transmitter, which is a device used to send and receive radio signals. MEG stands for Mega Electron-Volts, which is a unit of energy equal to one million electron-volts. Finally, BYTE is a unit of digital information that usually consists of eight bits. Together, these three words refer to the components of a gig, which is a unit of digital storage capacity.
