Expert Solution & Answer
Chapter 1, Problem 1MC
Program Description Answer
CPU’s job is to get the information and to perform actions commanded by the instructors to produce resultant information.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
CPU (Central Processing Unit):
- CPU is called as the Heart of a Computer, because it stores and retrieves data.
- It is the component of the computer which is responsible for executing many commands.
- CPU contains two parts namely: Control unit and Arithmetic Logic Unit.
- It is mainly used to get the instructions as well as to perform the mathematical operations.
Explanation for incorrect options:
Memory is a storage location of data which can be accessed directly.
Hence, the option “A” is wrong.
When the data is stored using any external memory device whose contents are non-volatile in nature are termed as “Secondary storage”.
Hence, the option “C” is wrong.
When the data is collected from the user through any device is called as input device.
Hence, the option “D” is wrong.

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.
