  4. C. External memory devices. Portable computers typically contain all the devices that users need to perform work away from the office; however, users have become accustomed to using additional items with their computers. For this reason, portables offer a wide range of I/O and expansion options to accommodate external FRU devices. The most common external devices used with portables include: external disk drives, external power sources and supplies, and External I/O devices. For more information, see the section "Portable Peripherals."

For more information, see the section "External Portable I/O."
