It came in 5-gigabyte (GB) and
10-GB models.
One of the quickest and easiest ways to
tell if you have a first-generation iPod
is to look at the scroll wheel. On the
first-generation iPod, the scroll wheel
is mechanical??”it physically moves
(see Figure 1-1). No other iPod has this
feature. The control buttons??”Play/
Pause, Menu, Forward, and Reverse??”
are also mechanical, and they all appear
around the scroll wheel.
The first-generation iPod connects to
computers and other devices through a
FireWire port, which you find at the top
of the unit (see Figure 1-2). Unlike later
models, the first-generation iPod connects
exclusively through FireWire. It does not
support any other type of data connection.
NOTE
As you probably already know, your iPod stores songs as
digital files on an internal hard drive very much like the
hard drive in a computer. (Later iPods, such as the iPod
mini and the iPod nano, do it a bit differently, as you??™ll
see later in this chapter.) The GB, or gigabyte, rating
determines the amount of storage space on the drive:
the larger the number, the more storage space.
