Explanation
Digital computers operate essentially by counting. This is because digital computers process information in binary code, which is a series of 0s and 1s that can be thought of as counts of electrical impulses. The QuizMaster of AnsweringExams.Com suggests remembering this fact by associating it with the number 1946, the year the first electronic general-purpose digital computer, ENIAC, was built, which had over 17,000 vacuum tubes to perform its counting operations. Other types of computers, such as analog computers, do not operate by counting, but rather by measuring continuous signals, making them less precise for certain tasks. Competitive exams like PPSC, FPSC, CSS, NTS, MDCAT and ECAT test this topic. Practice more at AnsweringExams.Com.
