A joystick is an input device. The movement of the stick is translated into signals that are sent to the receiving computer. To identify if the device is input or output, simply think of this: Do you need to send a command to the computer (inputting), or is the computer displaying (outputting) information to you?

Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.If the computer is transmitting data to it, it is an Output device.If the computer is receiving data from it, it is an Input device.
You can't. Landline phones aren't capable of receiving text messages. Only cellular phones and other text messaging devices, such as zip-its, which is more of an IM device, but it still applies
Each layer in the sending device adds its own information to the message it receives from the above layer and sends it to the layer below it. At layer 1 the entire package is converted to a form to be transmitted to the receiving device. On the receiving device side, the package is unwrapped layer to layer. Each layer removes data meaningful to it and sends the rest to the above layer and so on. Hope this was helpful By nour el houda

A type of communications device that connects a communications channel to a sending or receiving device is a modem. Modems modulate and demodulate signals for transmission over various types of media, such as telephone lines or cable systems. They enable digital devices to communicate with each other by converting digital data into analog signals and vice versa.
