Input and output (I/O) devices are the conduits through which information passes into and out of a computer. The three main types of I/O devices are input devices, output devices, and storage devices.
Input devices allow users to enter data into a computer. The most common type of input device is the keyboard. Other common input devices include the mouse, trackball, touchpad, joystick, scanner, and digital camera.
Output devices display information on a screen or print it out on paper. The most common type of output device is the monitor. Other common output devices include the printer, plotter, and speaker.
Storage devices are used to store data. The most common type of storage device is the hard drive. Other common storage devices include the CD-ROM, DVD-ROM, and flash drive.

What is input and output examples?
Input and output are two of the most fundamental concepts in computer science. Simply put, input is data that is given to a program, and output is the result of that program running.
There are a variety of different ways to provide input to a program. The most common is through a keyboard, but programs can also take input from files or other programs. Output can be displayed on the screen, written to a file, or sent to another program.
One of the simplest programs in the world is a program that just prints the string “Hello, world!” on the screen. Here is an example of how to write such a program in Python:
print(“Hello, world!”)
This program takes no input, and it prints the string “Hello, world!” on the screen.
Another common type of program is one that takes user input. For example, here is a program that asks the user for their name and prints it back to them:
name = input(“Please enter your name: “)
print(“Hello, ” + name + “!”)
This program takes user input and prints it back to them. The input is stored in the variable name, and then that variable is printed back out to the user.
What are the 5 input and output devices in a computer?
There are five main input and output devices in a computer. The first is the Central Processing Unit, or CPU. The CPU is the part of the computer that does all of the calculations. The second is the Random Access Memory, or RAM. RAM is where the computer stores data that is currently being used. The third is the Read-Only Memory, or ROM. ROM is where the computer stores data that is not currently being used. The fourth is the Hard Drive. The Hard Drive is where the computer stores all of its data. The fifth is the Display. The Display is where the computer shows its output.
What is input of computer?
Input is the information that is entered into a computer, for example, text, numbers, or images. The input is processed by the computer and the results are displayed on the screen or printed out. There are a variety of ways to enter information into a computer, including a keyboard, a touch screen, a microphone, or a scanner.
What is output in computer?
Output in computer is the result of a process or calculation. In other words, it is the information that is displayed on the screen or printed out. Output can be the result of a program or a command that you type in.
Which is output device?
There are a few different types of output devices that you may be using in your everyday life. The most common type of output device is a display, which is used to show text and images on a screen. There are also output devices that produce sound, such as loudspeakers and headphones. Finally, there are output devices that produce haptic feedback, or physical sensations, such as touch screens and vibration motors.
The most common type of output device is a display. A display is a device that uses pixels to create an image that can be viewed by a person. There are a few different types of displays, including LCDs, OLEDs, and E-Ink screens. LCDs are the most common type of display, and they use a backlight to produce an image. OLEDs are a newer type of display that do not require a backlight, and they produce a sharper image than LCDs. E-Ink screens are a type of display that uses tiny mirrors to create an image, and they are very power efficient.
Output devices that produce sound are becoming increasingly common. Loudspeakers are a type of speaker that uses a cone to produce sound. Headphones are a type of speaker that uses small speakers to produce sound directly into your ears. Headphones are a great way to listen to music or watch videos without disturbing other people.
Output devices that produce haptic feedback are also becoming increasingly common. Touch screens are a type of output device that uses sensors to detect when you touch the screen. When you touch the screen, the sensors send a signal to a vibration motor, which causes the screen to vibrate. This is called haptic feedback, and it can be used to provide feedback when you touch a button or menu item. Vibration motors are also used in devices such as cellphones and gaming controllers to provide haptic feedback when you touch the device.
What are 3 outputs of a computers?
There are three main outputs of a computer: audio, video, and data.
Audio is the result of sound waves being processed by a computer. The computer takes in the sound waves, changes their characteristics, and outputs them as audio. This can be done in a number of ways, including through a speaker, headphone jack, or HDMI port.
Video is the result of images being processed by a computer. The computer takes in the images, changes their characteristics, and outputs them as video. This can be done in a number of ways, including through a monitor, television, or projector.
Data is the result of information being processed by a computer. The computer takes in the information, changes its characteristics, and outputs it as data. This can be done in a number of ways, including through a printer, storage device, or network.
What is output of computer?
The output of a computer is the information that is displayed on the screen or sent to a printer. This information can be in the form of text, graphics, or even sound. The output of a computer is determined by the software that is running on it and the settings that are selected by the user.
