class Potato : Vegetable {
public override void message()
{
MessageBox.Show(”I'm a potato.”);
}
}
Given these class declarations, what will the following code display?
Vegetable v = new Potato();

Simulate on a vertical time axis (with events labeled with the senders names A-D) the contention period of FOUR equally distanced Ethernet stations that all attempt to transmit at T=0 a minimally sized frame, in the style of the binary Exponential Backoff Algorithm. Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2).
Use as coin flip (source of randomness) an ID written in binary.
use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.
Start be writing the ID, which is 904012207

Big State University
The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced
course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes
either one of these prerequisites and obtains the instructor's permission, however, will be allowed to
take MIS 260."
Tasks
1. Create a decision table that describes the Big State University course catalog regarding eligibility for
MIS 260. Show all possible rules.
2. Simplify the table you just created. Describe the results.
3. Draw a simplified decision tree to represent the Big State University catalog. Describe the results.
4. Why might you use a decision tree rather than a decision table?
What is the ALU result if the 4-bit ALU Control signal is 0100? What happens if the ALU Control signal is 0101?

Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forward
