Question
Chapter 4, Problem 4.2E
Program Plan Intro
Backup:
- The backup is the process of taking identical copy of file, data, or code which can be used when original data is lost, corrupted, or spoiled.
- The user should use high quality media to back up the files and the best option is optical disc or external hard drive.
Storage media for backups:
Hard drive:
- It is a storage device that stores and retrieves the data.
- It is a rotating disk coated with the magnetic materials and holds the data even when the power is off.
- Hard drives are 2.5 inches in size and its storage space ranges from 160 GB to 2 TB.
Optical disc:
- It is an electromagnetic data storage device that can be written to read using a low-powered laser beam.
- Examples of optical discs such as Compact Discs (CDs), and Digital Video Discs (DVDs). CD and DVD are the optical standards, which are less expensive.
- Optical discs can store up to 25 GB of data.
USB flash drive:
- Memory sticks, thumb drives, or jump drives are the various names for USB flash drive.
- It is compact and it is easy to use. After plugging the USB device into USB port, it is ready to perform the read and write operations.
- The storage capacity ranges from 128 MB to 256 GB.
Cloud storage:
- The cloud backup is a process of taking copies of the files and data into cloud.
- It maintains the backup hardware. The files are retrieved from anywhere but it requires internet connection.
- Many users are choosing cloud storage because it is not expensive.
- A single person can store up to 5 TB of data in Google cloud.

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.
