The illustration on the next page shows the basic computer system you now
have. So that you can expand your system’s capabilities, your computer has
both external ports and internal slots to which you can connect additional
hardware. Audio devices such as headphones and other sound equipment, as
well as a printer or scanner, all connect to appropriate external ports.
Also, devices that go inside the computer’s cover can increase its capabilities
and performance. Among these items are additional dynamic random-access
memory Dual Inline Memory Modules (DIMMs), a High Performance
Module (256K level 2 cache), and different kinds of expansion cards.
Instructions for installing these internal accessories are provided in Chapter 8,
“Installing Expansion Cards or Additional Memory.”
In addition, you can expand your computer by connecting it to a network.
WARNING
Before you connect any equipment to your computer, make
sure that your computer is plugged in (in order to ground it) and turned
off. If you connect equipment with the computer turned on, you can
damage your computer and your equipment.
