Bit field

Bit Fields are like special variables that can store many numbers at the same time. To do this they use something called 'Bits'. Bits are like the on-off switches that you might find in your house, they can either be turned on or off. Bit fields use these 'Bits' to store an entire group of numbers at once. They are often used in programming to store different kinds of information in a more efficient way than using normal variables.
