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:
Answer explained
Explanation:
From the previous question we know that while searching for n^(1/r) we don't have to look for guesses less than 0 and greater than n. Because for less than 0 it will be an imaginary number and for rth root of a non negative number can never be greater than itself. Hence lowEnough = 0 and tooHigh = n.
we need to find 5th root of 47226. The computation of root is costlier than computing power of a number. Therefore, we will look for a number whose 5th power is 47226. lowEnough = 0 and tooHigh = 47226 + 1. Question that should be asked on each step would be "Is 5th power of number < 47227?" we will stop when we find a number whose 5th power is 47226.
Answer:
You need to make use of the Brush tool for removing the unwanted part of an image.
Explanation:
Yes, it is the brush tool or the lasso tool that you can make use of. and you will find brush tools in all sorts of image processing software may it be the paint or Photoshop. It is common to both the raster-based and vector-based image processing software. And you can easily find it inside the tool section, and then make use of it to remove the unwanted parts from an image.
