if I ever get and iPhone and I ever break the case. For a cracked iPhone. Go over the cracks with color sharpies and wipe off the extra with a damp paper towel as you go :) I'm sure ill need this eventually.
Port - Most input/output devices are outside the computer case. These devices communicate with components inside the computer case through a wireless connection or through pcables attatched to the case at a connection called a port.
