I
IOCTL. Input/Output Control.
Internet Protocol Address. See IP.
I/O Ports. I/O ports are primarily dedicated to passing information into or out of the vehicle computer's memory. VC70
vehicle computers include Serial and USB ports.
IP. Internet Protocol. The IP part of the TCP/IP communications protocol. IP implements the network layer (layer 3) of the
protocol, which contains a network address and is used to route a message to a different network or subnetwork. IP
accepts "packets" from the layer 4 transport protocol (TCP or UDP), adds its own header to it and delivers a "datagram"
to the layer 2 data link protocol. It may also break the packet into fragments to support the maximum transmission unit
(MTU) of the network.
IP Address. (Internet Protocol address) The address of a computer attached to an IP network. Every client and server
station must have a unique IP address. A 32-bit address used by a computer on a IP network. Client workstations have
either a permanent address or one that is dynamically assigned to them each session. IP addresses are written as four
sets of numbers separated by periods; for example, 204.171.64.2.
IS-95. Interim Standard 95. The EIA/TIA standard that governs the operation of CDMA cellular service. Versions include
IS-95A and IS-95B. See CDMA.
L
LCD. See Liquid Crystal Display.
LED. A semiconductor diode (LED - Light Emitting Diode) used as an indicator, often in digital displays. The semiconductor
uses applied voltage to produce light of a certain frequency determined by the semiconductor's particular chemical
composition.
Liquid Crystal Display (LCD). A display that uses liquid crystal sealed between two glass plates. The crystals are excited
by precise electrical charges, causing them to reflect light outside according to their bias. They use little electricity and
react relatively quickly. They require external light to reflect their information to the user.
Light Emitting Diode. See LED.
O
ODI. See Open Data-Link Interface.
OEM. An Original Equipment Manufacturer manufactures products that are retailed under a brand name of a purchasing
firm.
Open Data-Link Interface (ODI). Novell's driver specification for an interface between network hardware and higher-level
protocols. It supports multiple protocols on a single NIC (Network Interface Controller). It is capable of understanding
