A computer is an electronic device that can be instructed to carry out sequences of arithmetic or logical operations automatically. The three main components of a computer are the central processing unit (CPU), the memory, and the input/output (I/O) devices.
The CPU is the part of the computer that performs the instructions of a program. The memory is where the CPU stores data and programs. The input/output devices are the parts of the computer that allow information to be entered into the computer and output from the computer.
There are many different types of input and output devices. Some of the most common input devices are the keyboard, mouse, and touchpad. The keyboard is used to enter text into the computer. The mouse is used to control the movement of the cursor on the screen and to select menu items. The touchpad is a type of mouse that is used on laptops. It is a small pad located on the bottom of the laptop that is used to control the cursor by touching it with a finger.
Some of the most common output devices are the monitor, printer, and speakers. The monitor is the screen on which the computer displays information. The printer is used to print documents and images. The speakers are used to play sound files.

What are 5 different input devices?
There are many different types of input devices that can be used with a computer. Some are more common than others, but they all have their own unique benefits and drawbacks.
The five most common input devices are the keyboard, the mouse, the touchpad, the joystick, and the trackball.
The keyboard is the most common input device, and is used to input text into a computer. It is also used to navigate around the desktop and to open programs. The keyboard has many different keys that can be used to perform different tasks.
The mouse is another common input device that is used to move the cursor on the screen and to select items. It is also used to open programs and to navigate around the desktop. The mouse has two buttons, a left button and a right button, that can be used to select items.
The touchpad is a common input device that is used on laptops. It is a small pad located near the keyboard that is used to input text and to move the cursor. The touchpad is also used to open programs and to navigate around the desktop.
The joystick is a common input device that is used to control movement in games and other applications. It has a joystick that can be used to move the cursor and to control movement. It also has buttons that can be used to perform different tasks.
The trackball is a common input device that is used to control the cursor. It has a ball that can be used to move the cursor around the screen. It also has buttons that can be used to perform different tasks.
What are 3 types of input devices?
There are three types of input devices: input devices that use light, input devices that use sound, and input devices that use touch.
Input devices that use light are called optical mice. An optical mouse uses a light-emitting diode (LED) and a photo sensor to track movement. The LED shines a light on the surface of the mouse pad or desk, and the photo sensor measures the amount of light that is reflected back. As the mouse is moved, the sensor detects changes in the reflected light and sends this information to the computer, which uses it to track the mouse’s movement.
Input devices that use sound are called microphones. A microphone is used to capture sound and convert it into an electronic signal that can be processed by a computer. Microphones are often used to record audio, but they can also be used to control computer functions by voice. For example, some speech recognition software allows you to control your computer by speaking into the microphone.
Input devices that use touch are called touchpads. A touchpad is a flat surface that you can use to control the movement of the cursor on your screen by touching it with your finger. Some laptops have touchpads that also allow you to scroll up and down and left and right by moving your finger along the edge of the touchpad.
