Bit: Computers deal with binary digits, or bits for short. A bit can be 0 or 1, equivalent or off or on.
Byte: One byte is eight binary digits, such as 1111001.
Kilobyte (KB): The smallest file stored on a smartphone, tablet or PC is typically four kilobytes (4KB) in size. A kilobyte is 1024 bytes. Therefore 1KB is the same as 1024 x 8 = 8192 binary digits.
Megabyte (MB): 1024KB equals one megabyte (MB).
Gigabyte (GB): There are 1024MB in one gigabyte.
Terabyte (TB): There are 1024GB in one terabyte (TB)
