Cards

Term
NIC
Definition
connectivity devices that enable a workstation, server, printer or other node to receive and transmit data over the network media
Term
Data Receiver
Definition
device on NIC that transmits and receives data signals
Term
bus
Definition
The circuit or signaling pathway used by the motherboard to transmit data to the computers componenets, including its memory, processor, hard disk and NIC
Term
expansion slots
Definition
openings with multiple electrical contacts that allow devices to connect to the computer's expanded bux
Term
PCIe - PCI Express

Definition
the primary difference between two USB standards
Term
firmware
Definition
set of data instructions that has been saved to a ROM chip
Term
device driver
Definition
software that enables an attached device to communicate with the computers OS. Are loaded into RAM upon computer start up
Term
ACT NIC LED
Definition
LED indicator is blinking, indicating that NIC is either transmitting or receiving data
Term
IRQ
Definition
a message to the computer's processor that instructs it to stop what it is doing and pay attention to something else
Term
interrupt
Definition
is the circuit board wire over which a device issues voltage to signal the IRQ request
Term
CMOS
Definition
microchip that requires very little energy to operate
Term
BIOS
Definition
simple set of instructions that enables a computer to initially recongize its hardware
Term
memory range
Definition
indicates in hex the area of memory that NIC and CPU use for exchanging or buffering data
Term
On board
Definition
NIC is integerated into motherboard
Term
firmware settings
Definition
a NIC's transmission characteristics are held in the adapters _________
Term
HUB
Definition
a repeaters with more than one output portm
Term
Interior Router
Definition
router that directs data b/w nodes an on autonomous LAN (or own owned & operated by a single organization)
Term
intelligent hubs
Definition
hubs that posess internal processing capabilities
Term
Bridges
Definition
devices that connect two network segments by analyzing incoming frames and makeing decisions about where to direct them based on each frame's MAC address.
Term
switches
Definition
connectivity devices that subdivide a network into smaller logical pieces or segments
Term
content switches
Definition
switches that operate anywhere b/w layer 4 and layer 7
Term
router
Definition
a mutliport connectivity devices that directs data b/w nodes on a network
Term
dynamic routing
Definition
routing techinique that automatically calculates the best path b/w two nodes
Term
static routing
Definition
routing technique in which network admin programs a router to use speciific path b/w nodes
Term
Gateways

combinations of networking hardware and software that connect two dissimilar kinds of networks
Term
CardBus
Definition
External peripheral devices that specifies a 32 bit interface running at 33MHz, which matches the PCI expansion board standards
Term
FireWire
Definition
peripheral bus, coded as IEEE 1394 sandards
Term
loopback adapter
Definition
a connector that plus into a port and crosses over the transmit line to receive line so that outgoing signals can be redirected into the computer for testing
Term
Cut-Through Mode
Definition
A switch running in this mode reads a frame's header and decides where to forward the data before it receives the entire packet
Term
Store and Forward Mode
Definition
switch reads the entire data frame into memory and checks it for accuracy before transmitting the information
Term
external
