Answer:
Blocking Mode
Explanation:
Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called 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 forwarding 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 blocking 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 allows only one active path to the destination while blocking all other paths to avoid switching loop.
Answer:
The correct answer for the given question is "Machine languages can be used to write programs that can run on any machine."
Explanation:
The machine language consist of binary digit i. e 0 and 1 .Computer can understand only the machine language .The machine language consist of code that is written in bits so it is used to express algorithms.When any program is compiled the compiler are converted into machine code so the machine language is produced by the compiler .
Machine language cannot used to write a program that run on any machine.
A table cell contains one piece of data
Answer:
The correct answer to the following question will be "Math.sqrt(area*2)".
Explanation:
- The Math.sqrt( ) method in JavaScript is used to find the squares root of the given figure provided to the feature as a variable.
- Syntax Math.sqrt(value) Variables: this function takes a single variable value that represents the amount whose square root is to be determined.
- The area of the figure is the number of squares needed to cover it entirely, like the tiles on the ground.
Area of the square = side times of the side.
Because each side of the square will be the same, the width of the square will only be one side.
Therefore, it would be the right answer.
