Cards

Term
100BaseFX
Definition
Fiber optic implementation of Ethernet that runs at 100 megabits per second. It uses baseband signaling. Maximum length of cable is 400 meters.
Term
10Base2
Definition
Also called Thinnet or Thin Ethernet LAN designed to run on common coax RG-58 cabling, almost exactly like the coax for cable television. It runs at 10 megabits per second and has a maximum segment length of 185 meters. It uses baseband signaling and BNC connectors.
Term
10BaseT
Definition
An Ethernet LAn designed to run on UTP cabling running at 10 megabits per second. The maximum length for the cabling between the NIC and the hub (or switch, repeater, etc) is 100 meters. It uses baseband signaling.
Term
ACPI
Definition
A power management specification that far surpasses its predecessor, APM, by providing support for hot swappable devices and better control of power modes.
Term
Backbone
Definition
A generalized term defining a primary cable or system that connects networks together.
Term
Card Services
Definition
A component of the operating systems that works in conjunction with socket services to recognize the function a particular PC Card and provide the specialized drivers needed to make the card work.
Term
CSMA/CD (Carrier Sense Multiple Access with Colloision Detection)
Definition
The access method Ethernet systems use in local area networking technologies enabling packets of data to flow through the network ultimately to reach address locations.
Term
DB25 connector
Definition
A D-shaped connector with 25 pins that are used for a variety of connecttions in the PC and networking world. Can be male (with prongs) or female (with holes) and have a varying number of pins or sockets.
Term
Docking Station
Definition
A platform into which you can install a portable computer. typically contains slots for expansion cards, bays for storage devices, and conectors for peripheral devices, such as printers and monitors. Once inserted inone, the portable computer essentially becomes a desktop model computer. When it is taken out, it becomes a portable computer again.
Term
Dot-matrix Printer
Definition
A printer that creates each character from an array of dots.
Term
Firewire
Definition
An IEEE 1394 standard to send wide-band signals over a thin connector system that plugs into TVs VCRs TV cameras, PCs, etc.
Term
Hibernation
Definition
a Special type of suspend where critical configuration information is written to the hard drive: upon a wake up event, the system is reinitialized, and the data is read fro the drive
Term
Hub
Definition
An electronic deivec that sits at the center of a star topology network, providing a common point for connection ofnetwork deivices.
Term
IEEE 1284
Definition
Also known as a parallel port this the standard for a connection for the synchronous, high speed flow of data along parallel lines to a device, usually a printer.
Term
IEEE 802.3
Definition
IEEE subcommitie that defined the standards for CSMA/CD (aka ethernet.)
Term
IPX/SPX
Definition
Protocol suite developed by Novell, primarily for supporting Novell Netware-based networks.
Term
Network
Definition
A collection of two or more computers interconected by telephone lines, coaxial cable, statellite links, radio , and some other communication technique
Term
Packet
Definition
Basic component of comunication over a network. A group of bits of fixed maximum size and well-defined format that is switced and transimited as a complete whole through a network
Term
