After you have installed the game, where do its parts exist?

A good answer might be:

• A program (that controls the action of the game.)
  • On the hard disk
• Data (the images and other information.)
  • On the hard disk

Input and output devices allow the computer system to interact with the outside world by moving data into and out of the system. An input device is used to bring data into the system. Some input devices are:

• Keyboard
• Mouse
• Microphone
• Bar code reader
• Graphics tablet

• Monitor
• Printer
• Speaker

Input/output devices are usually called I/O devices. They are directly connected to an electronic module inside the systems unit called a device controller. For example, the speakers of a multimedia computer system are directly connected to a device controller called an audio card (such as a Soundblaster), which in turn is connected to the rest of the system.

Sometimes secondary memory devices like the hard disk are called I/O devices (because they move data in and out of main memory.) What counts as an I/O device depends on how detailed you are looking at a computer system. In a general overview, secondary storage plays a different role than the I/O devices listed above.

QUESTION 6:

Most modern automobiles are controlled by a computer. Do you think that the computer in your car has:

• Input devices?
• Output devices?
• Main storage?
• Secondary storage?
