High quality external speakers can be expensive Advantages* Everyone in the room can hear the output from the computer.
They can help create an atmosphere or ambiance to accompany a presentation
They help blind people to use the computer because text can be converted into sound Printers are used to create a 'hard' copy of your work i.e. something that you can hold, hand to someone else or file away. A monitor (or screen) is the most commonly used output device.
