Data is transmitted or received by a computer in which form?

Data transmitted or received by a computer is primarily in digital form. Digital data is represented using binary code, which consists of zeros and ones. This binary system allows computers to efficiently process, store, and transmit information since computers operate using electronic signals that can easily represent these binary values.

Digital data offers a range of advantages, including higher accuracy and the ability to be easily compressed and encrypted. It is also more reliable in communication systems, making it the preferred method for data transmission in computing devices.

While other forms, such as analog, graphic, or text, can exist and may represent data in different contexts, they are not the primary means by which computers handle data. Analog signals, for example, can be converted into digital form using an analog-to-digital converter, but inherently, computers work with digital information. Hence, the focus on digital form as the correct answer reflects the standard operational framework within computer systems.
