The correct answer is: B. It represents the decimal numbers through a string of binary digits.
A digital computer is a computer that represents data and performs calculations using the digits 0 and 1. These digits are called bits, and they can be combined to represent numbers, letters, and other symbols. Digital computers are the most common type of computer today, and they are used for a wide variety of tasks, including word processing, spreadsheets, games, and internet browsing.
Analog computers, on the other hand, represent data and perform calculations using continuous values. For example, an analog computer might represent the position of a car on a map by using a voltage that varies continuously from 0 to 12 volts. Analog computers are less common than digital computers, but they are used in some specialized applications, such as controlling industrial processes.
Option A is incorrect because digital computers are typically more accurate than analog computers. This is because digital computers can represent numbers with a much higher precision than analog computers.
Option C is incorrect because digital computers are used for a wide variety of tasks, not just scientific applications.
Option D is incorrect because only option B is true.
Option E is incorrect because option B is true.
