Explanation
Portable computers are a category that includes notebook, laptop, palm, and hand-held computers. This answer is correct because these devices are designed to be mobile and can be easily carried around, allowing users to work or access information from anywhere. The QuizMaster of AnsweringExams.Com suggests remembering the term “portable” by associating it with the date 1973, when the first portable computer was released, to help recall that portable computers are the correct category for these devices. Other options are incorrect because they do not accurately describe the characteristics of notebook, laptop, palm, and hand-held computers, which are not typically associated with large-scale mainframe operations or hybrid systems. Competitive exams such as PPSC, FPSC, CSS, NTS, MDCAT and ECAT test this topic. Practice more at AnsweringExams.Com.
