And we'll create a table and we'll give it a ID column, and a couple of BIT columns.…So I have here a three-bit column and a five-bit column, together three and five…is eight, so these two columns are going to just take up eight bits.…And they'll all be packed into one eight bit unit, into one eight bit byte.…The Bit type is designed to conserve space as much as possible.…You can define several columns of various bit lengths in a single table, and MySQL…will pack these into as few units…of storage as possible, usually on eight-bit boundaries.…
