  • Page 187 IOWA-GX CPU Board AC ’97 Audio Codec 97 (AC’97) refers to a codec standard developed by Intel® in 1997. ACPI Advanced Configuration and Power Interface (ACPI) is an OS-directed configuration, power management, and thermal management interface. AHCI Advanced Host Controller Interface (AHCI) is a SATA Host controller register-level interface.
  • Page 188 IOWA-GX CPU Board CMOS Complimentary metal-oxide-conductor is an integrated circuit used in chips like static RAM and microprocessors. COM refers to serial ports. Serial ports offer serial communication to expansion devices. The serial port on a personal computer is usually a male DB-9 connector.
  • Page 189 IOWA-GX CPU Board Gigabit Ethernet (GbE) is an Ethernet version that transfers data at 1.0 Gbps and complies with the IEEE 802.3-2005 standard. GPIO General purpose input Hard disk drive (HDD) is a type of magnetic, non-volatile computer storage device that stores digitally encoded data.
  • Page 190 IOWA-GX CPU Board resolution of 320 x 240 pixels. Random Access Memory (RAM) is volatile memory that loses data when power is lost. RAM has very fast data transfer rates compared to other storage like hard drives. SATA Serial ATA (SATA) is a serial communications bus designed for data transfers between storage devices and the computer chipsets.
