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.
Cloud computing allows computers from all around the world that are not being used to be able to do extra computations. This removes many of the limitations of a single computer and lets the user calculate things much faster.
Answer:
The answer is choice "a".
Explanation:
Measurement is a number allocation in which the entity or event attributes that would be comparable with other objects or events. Its scope and implementation depending on context and discipline.
- Its main purposes could be defined as measurements for efficiency, tracking, health, fitness (design, mounting), and solving problems.
- Its calculation consists of the numerical assignment, representing attribute amounts according to the rules for objects and events.
I'm not too sure, but I can remove three of the options above. Artificial Intelligence programmers write code for Artificial Intelligence- tis in the name. Game tool programmers code for video games. Web programmers program webpages or apps for the web.
Of the two options left, I would say that it is most likely D. System Programmers. It's not a definite, though. Good luck!
The best option is (C) A portfolio made
up of 60% stocks, 30% mutual funds, and 10% Treasury bonds.
There are a lot of risks involved when investing in almost
anything. You may end up paying a lot for something that may not be worthwhile
and at the end of it all end up losing a lot more than you get. In this case,
more than half of the money has been invested in stocks and the prices of
stocks change daily. Investing in stocks may give a good return but remains
high risk to involve yourself in and should be avoided as much as possible.
