monitor
A joystick is an input device. It receives input from the user in the form of it's operation which it then passes on to the computer. Speakers are an example of an output device. They receive no input from the user, and only output (sound in this case). You can think of an input device as something that gives the computer information. And an output device as something that receives information from the computer.
When i did I.T. we always described monitors as output device not an input device. as it can not send information to the pc it only displays.
Pendrive is not a input device nor output device IT is STORAGE DEVICE. storage device, only data can be saved in pen drive.
No, it can output any type of audio.
It depends how you define these terms. Technically it is both, since floppy drives can be written to as well as read from. However, the term 'output device' normally refers to a means to provide information to the user, such as a screen, printer or speakers. Since a floppy drive can not be used to output information directly to the user (only to another computer), it could equally be argued that it is an input device.
Input because it is sending data to the computer.
Only the scanner is an input device, that supplies information to the computer. The monitor, speaker, and printer all take information from the computer and convert it into output for the computer user.
That's not compulsory
No. Very few actually do. The monitor is actually an output device. An output device only receives output when instructed to.
A microphone and a computer mouse has only an output. That is an input device. A loudspeaker and a printer has only an input. That is an output device. A read-write CD/DVD, floppy disk, tape drive, and hard drive are all I/O devices because they can be used to store and retrieve data.
An input device is basically any device or peice of equipment that you connect to a computer ect that sends data into the computer to be processed. Examples can include anything from keyboards or mice to temperature and pH probes to digital cameras. Note that devices such as printers and moniters are OUTPUT devices, ie they display information.
