Answer:
All of the above
Explanation:
An interrupt priority scheme is a system which decides the priority at which various work is done and it perform all of the above mention task so therefore all of the above is the right answer.
Answer:
The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions.
Answer:
Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
- Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops.
- These loops are called physical loops.
- When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
- This affects the performance of the network as the result of broadcast packets flooding.
- STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
- Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
- Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
- This information helps STP to eliminate the redundant paths.
- So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.
Answer:
computer means an electronic machine which process raw data and gives meaningful information to the user
Answer:
STP mainly uses 5 states in a network, in which some states are replaced in RSTP which improves the time efficiency.
Explanation:
STP mainly uses five states i.e. Learning, Listening, Blocking, Disabling and Forwarding to overcome the problem of collision in a network.
RSTP replaced the three states of STP i.e listening, learning, and blocking by Discarding, which results in the time efficiency as compared to STP.
As STP takes minutes to complete the network inter connectivity, RSTP completes it in seconds.
This is one of the main reason why an administrator want to change to RSTP.
