100BaseFX

Front 2

Also called Thinnet or Thin Ethernet an ethernet LAN designed to run on common coas RG-58 cabling, almst exactly like the coax for cable television. It runs at 10 megabits per second and has a max segment length of 185 meters. It uses baseband signaling and BNC connectors.

10Base2

Front 3

An Ethernet LAN designed to run on UTP cabling running at 10 megabits per second. The max length for the cabling between the NIC and the hub or switch repeater,etc. is 100 meters. It uses baseband signaling.

Back 3

10BaseT

Front 4

A power management specificaiton that far surpasses its predecessor, APM, by providing support for hot swappable devices and better control of power modes.

Back 4

ACPI

Front 5

A generalized term defining a primary cable or system that connects networks together.

Back 5

Backbone

Front 6

A component of the operating system that works in conjunction with socket services to recognize the funciotn of a particular PC Card and provide the specialized drivers needed to make the card work.

Back 6

Card Services

Front 7

the access method Ethernet sysems use in local area networking technologies enabling packets of data to flow through the network ultimately to reach address locations.

Back 7

CSMA/CD (Carrier Sense Multible Access wiht Collision Detection)

Front 8

A D shaped connector with 25 pins that are used for a variety of connecitons in the PC and networking world. Can be male (with prongs) or female(with holes) and have a varying number of pins or sockets.

Back 8

DB25 Connector

Front 9

A platform into which you can install a portable computer. Typically contains slots for expansion cards, bays for storage devices, and connectors for peripheral devices, such as printer and monitors. Once inserted in one the portable computer essentially becomes a desktop model computer. When it is taken out, it becomes a portable computer again.

Back 9

Docking Station

Front 10

A printer that creates each character from an array of dots. Pins striking a ribbon against the paper, one pin for each dot position, form the dots. The printer may ba serial printer (printing one character at a time) or a line printer.

Back 10

Dot matrix Printer

Front 11

An IEEE 1394 standared to send wide band signals over a thin connector system that plugs into TVs, VCRs, TB cameras, PCs etc. This serial bus devloped by Apple and Texas Insturments, enables connection of 60 devices at speeds ranging from 100 to 400 megabits per second.

Back 11

Firewire

Front 12

A special type of suspend where critical configuration information is written to the hard drive; upon a wakeup event the system is reinitialized, and the data is read from the drive to return the system to the state it was in prior to suspend.

Back 12

Hibernation

Front 13

An electonic device that sits at the center of a star topology network, providing a common point for the connection of network devices. Ina 10BaseT Ethernet network, the hub contains the electronic equivalent of a properly terminated bus cable, in Token Ring network, the hub contains the electronic equivalent of a ring.

Back 13

Hub

Front 14

Also know as a parallel port this is the standard for a conneciton for the synchronous, high speed flow of data along parallel lines to a device, usually a printer.

Back 14

IEEE 1284

Front 15

IEEE subcommittee that defined the standards for CSMA/CD (a.k.a. Ethernet)

Back 15

IEEE 802.3

Front 16

Protocol suite developed by Vovell, primarily for supporting novell net ware based networks.

Back 16

IPX/SPX

Front 17

A colletion of two or more computers interconnected by telephone lines, coaxial cables, satellite links, radio, and or some other communication technique.

Back 17

Network

Front 18

Basic component of communicaiton over a network. A group of bis of fixed max size and well defined format that is switched and transmitted as a complete whole through a network. It contains source and destination address, data, and control.

Back 18

Packet

Front 19

A credit card size adapter cards that add funcitonality in many notebook coputer, PDAs and other computer devices. The term replaced the oler term PCMCIA.

Back 19

PC Card

Front 20

A USB device that plugs into a USB port and offers common PC ports, such as serial, parallel, USB, network and PS/2 connections. Used primarily wiht laptop computers.

Back 20

Port Replicator

Front 21

The page description language (PDL) developed by Hewlett Packard and used in many of their laser and ink jet printers. After version 5, it supports a scalable font technology called Intellifont.

Back 21

Printer Control Language (PCL)

Front 22

A special CPU mode that enables the CPU to reduce power consumption via the selective shutdown of peripherals.

Back 22

System Management Mode (SNM)

Front 23

Printers that use heat to create an image on the medium htere are two main types; direct, which uses heat sensitive paer, and wax printers, which use a wax imbedded film to create the image.

Back 23

Thermal Printer

Front 24

A LAN and protocol in which nodes are connected togethert in a ring; a special packet called a token passed form node to node around the ring controls communication. A node can send data only when it receives the token and the token is not in use. This avoids the collision problems endemic to Ethernet networks.

Back 24

Token Ring

Front 25

A popular type of cabling for networks, composed of pairs of wires twisted around each other at specific intervals. The twists serve to reduce interference also called crosstalk. The cable has no metallic shielding to protect the wires from external interference, unlike its cousin, STP.

Back 25

UTP ( Unshielded Twisted Pair)
