ANSWER✔✔-Token |Ring |topology
A |deterministic |network |- |CORRECT |ANSWER✔✔-Token |Ring |Topology
Each |station |connected |to |the |network |ensures |access |for |transmission |of |its |messages |at |
regular |or |fixed |time |intervals |- |CORRECT |ANSWER✔✔-Deterministic
,What |are |the |disadvantages |of |the |Token |Ring |system? |- |CORRECT |ANSWER✔✔-1. |If |an |error |
changes |the |token |pattern, |it |can |cause |the |token |to |stop |circulating.
What |is |a |disadvantage |of |the |Token |Ring |system |from |the |troubleshooting |and |maintenance?
|- |CORRECT |ANSWER✔✔-The |token |ring |path |must |be |temporarily |broken |or |interrupted |if |a |
computer |or |any |device |on |the |network |is |to |be |removed |or |added |to |the |network.
What |is |a |solution |to |the |troubleshooting |and |maintenance |disadvantages |of |the |Token |Ring |
system? |- |CORRECT |ANSWER✔✔-Connect |each |computer |or |device |on |the |network |to |a |
central |token |ring |hub.
A |device |that |manages |the |passing |of |the |token |instead |of |relying |on |individual |computers |to |
pass |it. |- |CORRECT |ANSWER✔✔-Token |ring |hub
How |does |the |token |ring |hub |improve |the |network? |- |CORRECT |ANSWER✔✔-It |improves |the |
reliability |of |the |network.
Topology |whereas |the |computers |share |the |media |or |coaxial |cable |for |data |transmission. |- |
CORRECT |ANSWER✔✔-Bus |topology
The |coaxial |cable |that |is |looped |through |each |networking |device |to |transmit |data |in |a |bus |
topology |- |CORRECT |ANSWER✔✔-ThinNet
In |this |topology, |all |devices |on |the |network |can |see |each |other's |data |traffic. |- |CORRECT |
ANSWER✔✔-Bus |topology
Topology |whereas |each |computer |must |wait |for |pauses |in |transmission |or |until |the |
transmission |from |one |device |is |complete |before |initiating |a |new |transmission |onto |the |
network. |- |CORRECT |ANSWER✔✔-Bus |topology
, What |are |the |disadvantages |of |a |bus |topology? |- |CORRECT |ANSWER✔✔-"1. |Data |can |be |
corrupted |if |ore |than |one |device |on |the |network |transmits |at |the |same |time |and |will |have |to |
be |resubmitted.
2. |The |use |of |the |shared |coaxial |cable |prevents |data |transmission |from |being |very |bandwidth-
efficient."
Which |topology |is |seldomly |used |in |modern |networks? |- |CORRECT |ANSWER✔✔-Bus |topology
What |is |the |most |common |topology |used |in |today's |LANs? |- |CORRECT |ANSWER✔✔-Star |
topology
Topology |that |uses |twisted-pair |cables |with |modular |plugs |to |connect |computers |and |other |
networking |devices. |- |CORRECT |ANSWER✔✔-Star |topology
Topology |whereas |each |device |is |connected |to |a |switch |or |hub |- |CORRECT |ANSWER✔✔-Star
A |switch |or |hub |facilitates |the |transfer |of |data |between |networking |devices |in |this |topology |- |
CORRECT |ANSWER✔✔-star
Transmits |data |to |all |the |devices |connected |in |the |star |network |- |CORRECT |ANSWER✔✔-hub
Also |called |a |multiport |repeater |- |CORRECT |ANSWER✔✔-hub
Not |meant |for |large |networks, |but |are |still |used |in |some |smaller, |slower |speed |LANs |- |
CORRECT |ANSWER✔✔-hub
A |transmission |from |a |hub |in |a |star |network |to |all |the |devices |in |the |network |connected |to |
the |hub |- |CORRECT |ANSWER✔✔-broadcast
