DATA STORAGE

By Grace Mchomvu

• All programs and data stored inside a digital device are stored in binary format.

• A single binary digit (1 or 0) stored inside a digital device is known as a bit. Special switches called transistors are used to represent each binary digit inside a digital device.

• When data is stored inside a computer, the bits used to represent the data can be grouped together and processed in larger units, shown in the diagram below.
