I/O Ports. interface The connection between two devices, defined by common physical characteristics, signal
characteristics, and signal meanings. Types of interfaces include RS-232 and PCMCIA.
Input/Output Ports. I/O ports are primarily dedicated to passing information into or out of the terminal’s memory.
CA10 includes 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.
K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and
Decrypting .
L
LED Indicator. 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.
Light Emitting Diode. See LED .
M
MAC. a Media Access Control (MAC) address is a unique identifier assigned to a network devices (such as the
CA10 or Access Point) by the manufacturer for identification.
MC. Mobile Computer.
N
NDS . The Domain Name System (DNS) is a hierarchical naming system for computers connected to a network.
The NDS serves as the "phone book" for the Internet by translating human-friendly computer host names into
IP addresses. For example, www.motorola.com translates to 72.247.207.224.
