24 Chapter 3 Using Your Computer
Your iMac G5 comes with five USB ports ( ) (three high-speed USB 2.0 ports on the
back of the computer and two USB 1.1 ports on the keyboard), which you can use to
connect many types of external devices, including printers, scanners, digital cameras,
game pads, joysticks, keyboards, and floppy disk drives. USB makes it easy to connect
peripherals. In most cases you can connect and disconnect a USB device while the
computer is running. Once you connect the device, it is ready to use.
Using USB Devices
To use a USB device with your computer, simply connect the device to the computer.
Your computer automatically accesses the necessary software whenever you connect a
new device.
You can connect USB 1.1 devices and high-speed USB 2.0 devices to the USB 2.0 ports
on the back of your computer. USB 1.1 devices won’t take advantage of the USB 2.0
higher transfer rate.
Likewise, you can connect USB 2.0 devices to the USB 1.1 ports on your keyboard, but
they may operate at slower speeds.
Note: Apple has already included software to work with many USB devices. When you
connect a USB device, if your iMac G5 cannot find the correct software, you can install
the software that came with the device or check the device manufacturer’s website for
the latest software.
