Chapter 12, Problem 15RQ
Explanation of Solution
Purpose of a hot site:
- The hot site is a duplicate,
operational hardware system that is used immediately as a backup when the primary computer has a problem. - It provides a safe location where a company’s work can be continued during a disaster.
Difference between hot site and cold site:
| Hot site | Cold site |
| Hot site is a duplicate, operational hardware system or an immediate access to one through a specialized vendor. | Cold site is a computer environment that includes rooms, data storage devices, telecommunications links, electrical service and similar equipment... |

For the CSMA protocol (without collision detection), indicate which packets are successfully
transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to
each of the other nodes. You can assume that if a packet experiences a collision or senses the
channel busy, then that node will not attempt a retransmission of that packet until sometime after
t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.]

Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?
Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
