In what form is data stored and manipulated in a computer?

Data in a computer is primarily stored and manipulated in digital form. This is due to the way computers operate using binary language, which involves sequences of bits that represent data as on (1) or off (0). Digital form enables efficient processing, storage, and transmission of data, allowing for complex operations and interactions.

While analog form relates to a continuous signal that represents physical measurements, and text form can be a type of digital data but isn't a broader classification, digital form encompasses all types of information processed by a computer, including text, images, audio, and video, which are all ultimately converted into digital data for manipulation. Visual form, while relevant to how data may be presented, is not a method of storage or manipulation but rather a way that data can be displayed or visualized after being processed. Therefore, the correct choice is digital form, as it accurately describes the universal format in which computers operate.
