Question | Answer |
operate in the physical layer | repeater |
cant interpret the data they retransmit | repeater |
cant direct data to their destination | repeater |
only one input and output port | repeater |
allows you to extend a network cheaply | repeater |
repeater with more then one outpout port | hub |
operate at the physical layer | hub |
accepts signals from a transmitting node and sends them out to all connected nodes in a broadcast manner | hub |
allows the hub to connect to another hub | uplink port |
all devices connected share the same amount of bandwith and collision domain | hub |
do nothing but repeat signals | passive hubs |
have many functions and can be managed anywhere on the network | intelligent or managed hubs |
regenerate a signal over an entire network | repeaters |
devices that connect two networks | bridges |
analyze incoming frames and make decisions about where to send them based on the frames MAC address | bridges |
operate at the data link layer | bridge |
move data more rapidly than traditional routers because they are protocol independent | bridge |
to translate between two segments it reads the frames destination MAC address and decides to filter it or send it forward | bridge |
it reads the MAC address and searches its database and decides if the address is is on its segement or a different segment | bridge |
connectivity devices that subdivides a network into smaller logical pieces or segments | switches |
interpret MAC address information | switches |
can turn a shared channel into several channels | switch |
each on the switch acts like a bridge | port |
each device connected to a can turn a shared channel into sevreal channels | switch |
reads a frames header/MAC address and decides where to forward the data before it receives the entire packet | cut thru mode |
best suited to small workgroupd where speed is important | cut thru mode |
reads the entire data frame into memory and checks it for accuracy before sending the data | store and forward mode |
bettter suited for larger LAN environments because there are less data errors | store and forward mode |
logical seperate networks within networks by grouping a number of ports into a broadcast domain | VLAN |
combination of ports that make up a Layer 2 segment | broadcast domain or subnet |
seperating groups of users who need special security or network functions | reason for using a VLAN |
isolating connections with heay or unpredictable traffic patterns | reason for using a VLAN |
identifying groups of devices whose data should be given priority handling | reason for using a VLAN |
functions in the data link layer | spanning tree protocol |
calculates paths to avoid traffic loops and blocks links that would create loops | stp |
a glorified bridge | switch |
only one port and one bridge can can forward frames from the root bridge to the destination bridge | stp |
provides the basis for all subsequent calculations | root bridge |
switches operate in Layer of the OSI model | 2 |
routers operate in Layer | 3 |
hubs operate in Layer | 1 |
a switch capable of interpreting layer 3 data | layer 3 or routing switch |
switches that operate anywhere between layers 4 and layer 7 | content or application switches |
multiport connectivity device that directs data between nodes on a network | router |
receives an incoming packet ,reads the logical addresing information and determines which network to deliver it to | routers |
operates at the network layer | router |
must be configured to recognize a certain network layer protocol before they can transmit data using that protocol | router |
can determine the shortest fastest path between two nodes | router |
connect dissimiliar networks determine the best path for data from point A to B | router |
reroute traffic if one path is not working provide high network fault tolerance | router |
directs data between nodes on a Lan that is operated by a single organization | interior router |
direct data between an employees workstation and his supervisors workstation down the hall | exterior router |
connect a business using a LAN operated by a single organization to a WAN | border or gateway router |
automatically calcualtes the best path between two nodes and stores the info in a table | dynamic routing |
programmed to use specific paths between two nodes | static routing |
used only to connect data about current network status and help decide the best path | routing protocols |
time it takes for a router to recognize the best path in the event of a change | convergence time |
distaance vector link state hybrid of the two | three types of routing protocols |
