Which of the following is true about digital computers.
Answer Details
The correct option is "they represent numbers through a string of binary digits".
Digital computers are electronic devices that operate on digital data, which is represented as a string of binary digits (bits), each of which can take one of two values, 0 or 1. These bits are processed by the computer's central processing unit (CPU) using logical operations, and the resulting output is also in digital form. This makes digital computers suitable for a wide range of applications, from simple calculations to complex data processing and storage. The other options mentioned are not true for all digital computers. While some older computers used magnetic core memory, modern computers use other types of memory such as solid-state drives. Digital computers can process both continuous and discrete data, but they represent all data as a string of binary digits. Finally, while digital computers are used extensively in scientific applications, they are also used in many other areas such as business, entertainment, and education.
