The Arrow keys move the typing cursor up, down, and sideways as indicated by the direction the arrow is pointing. Remember these keys are repeater keys. Holding them down causes the cursor to move continuously until you release the key. The final section is the number pad on the extreme right of the keyboard.
The Tower
The Modem: The modem is an electronic card located inside your tower or PC desk case that you plug your |
phone line into in order to
get on the internet or use your PC to
send faxes or make and receive phone calls.
Surge Protector
The disks (called media): Disks for the PC come in two flavors: 3.5" floppy disks and CD disks (about 4"). The floppy disk below is on the left. A compact disk ( CD) is on the right.
 You will use 3.5" disks to save files or to retrieve files. You will use compact disks (CDs) to retrieve information that's written on them and to install software on your PC. Most software programs come to you in a box of CDs. So you will remove the CDs from the box and use them to install the software.

The keys are laid
out like an adding
machine. Their only
purpose is to serve
the needs of people
who prefer the adding
machine layout. Everything
on the number pad can
be done elsewhere on the
main keyboard.
The tower contains the electronic "guts"
of the PC. The guts can include the
fixed disk drive, the floppy disk drive, the
modem, and more.
This device protects your
delicate PC and its peripherals
from lightning and other
electrical shocking. All your
equipment should be plugged
into the surge protector unless
the instructions tell you otherwise
