C
CAN Bus. Controller Area Network is a vehicle bus standard designed to allow microcontrollers and devices to communicate
with each other within a vehicle without a host computer.
Cold Boot. A cold boot restarts the vehicle computer and erases all user stored records and entries.
COM port. Communication port; ports are identified by number, e.g., COM1, COM2.
D
DDR2. Double data rate synchronous dynamic random-access memory interface. Memory type that DDR2 allows higher
bus speed and requires lower power.
E
EMDK. Enterprise Mobility Developer's Kit.
EMMC. Embedded Multi Media Card. NAND Flash memory and controller with multimedia card interface.
ESD. Electro-Static Discharge.
F
Flash Memory. Flash memory is nonvolatile, semi-permanent storage that can be electronically erased in the circuit and
reprogrammed. The vehicle computers use Flash memory to store the operating system, and the vehicle computer
emulators.
H

HID. USB human interface device class (USB HID class) is a part of the USB specification for computer peripherals. It
specifies a type of computer hardware for human interface devices such as Laser scanners, Imagers, keyboards or
mouse devices. The same HID protocol is used unmodified in Bluetooth human interface devices.[2] The Bluetooth
profile specification only points readers to the USB HID documentation. In this sense those devices also belong to the
USB HID class.
Hz. Hertz; A unit of frequency equal to one cycle per second.
Host Computer. A computer that serves other vehicle computers in a network, providing such services as computation,
database access, supervisory programs and network control.
