Which input device allows users to type data and instructions into computer memory?

• A. mouse
• B. keyboard
• C. scanner
• D. trackpad

Answer: (B)

The keyboard is the primary input device used to type data and instructions directly into a computer's memory. It consists of keys that represent letters, numbers, symbols, and functions, which users can press to enter information. This capability makes the keyboard essential for a range of tasks such as document creation, programming, and executing commands. In contrast, a mouse serves as a pointing device that helps users navigate the graphical interface of a computer, allowing for selections and actions without the need for typing. A scanner is utilized to convert physical documents into digital format, but it does not enable direct data entry. Similarly, a trackpad, often found on laptops, acts as a pointing device like a mouse, allowing for navigation and control through physical touch rather than typed input. Thus, while all these devices serve important functions in computing, the keyboard is specifically designed for typing data and instructions.
