Which of the following is not a type of computer on the basis of operation?

Answer Details

Computers can be classified in several different ways, and one important classification is based on the mode of operation, that is, the type of data the computer is designed to process and how it processes that data.

Under this classification, there are exactly three recognised categories. A digital computer processes discrete data using binary digits. An analog computer processes continuously varying physical quantities, such as voltage or temperature. A hybrid computer combines features of both digital and analog computers, processing both discrete and continuous data.

"Remote" is not a category within this classification at all. Remote refers to the location or method of access to a computer, for example accessing a machine over a network from a distant place, which has nothing to do with how the computer processes data internally. A computer can be digital, analog, or hybrid regardless of whether it is accessed remotely or used locally.

Exam tip: when a question lists "types of computers by mode of operation," check that each option genuinely describes a way of processing data (digital, analog, hybrid); anything describing location or access method, like "remote," does not belong in that classification.
