Answer: Option D. -> Numbers
Computers are electronic machines that process data into meaningful information. The raw data inputted into a computer needs to be processed, analyzed, and transformed into useful information that can be used by humans. Computers work with various types of data, such as text, images, audio, and video. However, the primary way that computers process data is through numerical data or numbers.
Computers use binary digits or bits, which can represent either 0 or 1, to store and process information. These bits are organized into groups of 8, known as bytes, to represent different types of data. For instance, characters are represented by their corresponding ASCII code, which is a numerical value. Similarly, images and videos are made up of pixels, which are also represented by numbers.
Here are some reasons why computers work exclusively with numbers:
  1. Arithmetic operations: Computers perform various arithmetic operations such as addition, subtraction, multiplication, and division, which all require numerical data.
  2. Memory storage: Computers store data in binary form, which means that everything is stored as numbers.
  3. Algorithms: Algorithms, which are a set of instructions used to solve a particular problem, are also based on numerical data.
  4. Data analysis: Data analysis, which involves processing large amounts of data to identify patterns and trends, relies heavily on numerical data.
In conclusion, while computers can work with various types of data, they process data into meaningful information by working exclusively with numerical data or numbers.
