What device is a keyboard and mouse?

A keyboard and mouse are both considered input devices. They are essential components of a computer system and are used to allow users to interact with the computer or other digital systems. Specifically, these devices are classified as:

1. Keyboard:

• Definition: A keyboard is a device used to input text, numbers, and commands into a computer or other devices. It consists of a set of keys, including letters, numbers, function keys, and control keys (like "Enter", "Shift", "Ctrl").
• Type of Input: Textual/Command Input
• Function: Primarily used for typing, but also for navigating menus, executing commands, and interacting with software applications.

2. Mouse:

• Definition: A mouse is a pointing device that allows users to interact with a computer by controlling the movement of a cursor on the screen. It typically has buttons (usually a left-click, right-click, and sometimes additional buttons) and a scroll wheel.
• Type of Input: Pointing/Selection Input
• Function: The mouse is used for selecting, moving, or dragging items on the screen, as well as for executing commands by clicking.

Classification of Devices:

Both a keyboard and a mouse are considered human interface devices (HID) because they translate human actions (typing and moving) into commands the computer can understand. They also fall under the broader category of peripherals, which are devices that add functionality to a computer but are not essential for basic operation.

Key Categories for Keyboard and Mouse:

• Input Devices: Both the keyboard and mouse are designed to send input signals to the computer.
• Peripherals: They are external devices connected to a computer to enhance its functionality.
• Pointing and Typing Devices: The mouse is a pointing device, and the keyboard is a typing device.
• Control Devices: Both allow users to control various aspects of the computer, whether through text input (keyboard) or interaction with the graphical user interface (mouse).

Summary:

• Keyboard and Mouse are both input devices used to interact with a computer.
• Keyboard is for typing and giving textual input, while Mouse is for pointing, selecting, and controlling the on-screen cursor.
• They are classified as peripherals or human interface devices (HID) in the context of computers.
