Module 1.2 Flashcards
A device that converts one media signaling type to another
Media Converter
A device that performs some type of signal modulation and demodulation, such as sending digital data over an analog line.
Modem
OSI model layer is responsible for transferring data between nodes.
Data Link Layer
a segment is one where all nodes can send traffic to one another using hardware addresses, regardless of whether they share access to the same media
Data Link layer,
The ___________ layer organizes the stream of bits arriving from the physical layer into structured units called frames.
data link
With Data Link Layer each frame contains a ___________ packet as its payload.
network layer
A _________ joins an end system host to network media (cabling or wireless) and enables it to communicate over the network by assembling and disassembling frames.
NIC
A ___________ is a type of intermediate system that joins physical network segments while minimizing the performance reduction of having more nodes on the same network
bridge
An advanced type of bridge with many ports. A ___________ creates links between large numbers of nodes more efficiently.
switch
An ____ allows nodes with wireless network cards to communicate and creates a bridge between wireless networks and wired ones.
Wireless access points
responsible for moving data around a network of networks, known as an internetwork or the Internet
Network Layer 3
An intermediate system working at the Network layer capable of forwarding packets around logical networks of different layer 1 and layer 2 types. Its the main appliance for working at layer 3.
Router
The network layer forwards information between networks by examining the destination network-layer address or logical ____________
Network address.
The ___________ layers of the OSI model are primarily concerned with moving frames and datagrams between nodes and networks
first three
OSI model layer responsible for ensuring reliable data delivery.
Transport Layer
