• RAM (random access memory)
Your computer uses dual in-line memory modules (DIMMs) for the random
access memory (RAM). For information about installing additional memory,
see the section“Installing and Removing RAM” on page 48.
• Drive Bays
The front of the computer has several drive bays. Counting from the top of the
computer:
– The top bay (Bay 1) contains the factory-installed CD-ROM/DVD-ROM
drive.
– In single-drive systems, bays 2 and 3 are usually empty. However, if you
ordered a second hard drive, it will be factory-installed in one of these
bays.
– Bay 4 contains the factory-installed hard drive.
– Bay 5 is usually empty.
You can install additional hard drives in the empty bays. For information, see
the section“Installing a Hard Drive” on page 49.
• Expansion Slots
There are a number of 32-bit Peripheral Component Interconnect (PCI) and
slower 16-bit Industry-Standard Architecture (ISA) expansion slots on the sys-
tem board. You can easily identify the difference between these two slot types.
ISA slots are twice as long and typically darker than PCI slots. Each time you
add a new card (expansion board) such as a video adapter or internal modem,
you install it in one of the available expansion slots. For information about in-
stalling and removing expansion cards, see the section “Installing Expansion
Cards” on page 51.
