content
Switches that operate anywhere between Layer 4 and Layer 7 are also known as ____ switches.
router
A ____ is a multiport connectivity device that directs data between nodes on a network.
static
____ routing is a technique in which a network administrator programs a router to use specific paths between nodes.
gateways
____ are combinations of networking hardware and software that connect two dissimilar kinds of networks.
bus
A computer's ____________________ is the circuit, or signaling pathway, used by the motherboard to transmit data to the computer's components, including its memory, processor, hard disk, and NIC.
on-board
A(n) ____________________ NIC is integrated into the motherboard.
device driver
A(n) ____________________ is software that enables an attached device to communicate with the computer's operating system.
memory range
The ____________________ indicates, in hexadecimal notation, the area of memory that the NIC and CPU use for exchanging, or buffering, data.
interior

repeater
Have no means to interpret the data they retransmit.
firewire
Uses the IEEE 1394 standard.
cut-through mode
A switch running in this mode reads a frame's header and decides where to forward the data before it receives the entire packet.
bridge
Devices that connect two network segments by analyzing incoming frames and making decisions about where to direct them based on each frame's MAC address.
cardbus
External peripheral device specifying 32-bit interface running at 33 MHz.
switch
Connectivity device that subdivides a network into smaller logical pieces.
PCIe
Supports up to 16 lanes.
store-and-forward mode
A switch running in this mode reads the entire data frame into its memory and checks it for accuracy before transmitting the information.
loopback adapter
Plugs into a port and crosses over the transmit line to the receive line so that outgoing signals can be redirected into the computer for testing.
