Suppose users share a 3 Mbps link. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time. (See the discussion of packet switching versus circuit switching in Section 1.3.)
- a. When circuit switching is used, how many users can be supported?
- b. For the remainder of this problem, suppose packet switching is used. Find the probability that a given user is transmitting.
- c. Suppose there are 120 users. Find the probability that at any given time, exactly n users are transmitting simultaneously. (Hint: Use the binomial distribution.)
- d. Find the probability that there are 21 or more users transmitting simultaneously.

Answers within 5% error will be considered correct. Enter answer herearrow_forwardMany IT implementations are operated as projects. Project stakeholders are vital aspects of the project team. Describe a project that you have worked on and the roles of each member on the team, and then answer the following questions. If you have never been on a project, find one online and answer the following questions. Why is it important to understand the role that each member plays on the team? What organization structure was in place for the project? Was the organizational structure optimal, and if so, why was it optimal? If it was not optimal, what structure would have been the optimal structure and why?arrow_forward

- Conduct a comprehensive study on Botnet networks, focusing on their architecture and functionality. Provide a detailed analysis of their control mechanisms via C2 (Command and Control) structures, and classify the different types of Botnets (centralized, decentralized, hybrid). Explain their primary uses in offensive contexts and discuss the evolution of detection and mitigation techniques in light of technological advancements in cybersecurity. Additional Note: Design a complete Botnet simulator using Python programming, including both the C2 server and the bot client.
