A. Imagine in an office building there are 3 floors and, on each floor, there are 7 employees working on their computers. Unfortunately, all the floors do not have a dedicated printer. There is only one shared printer on the second floor. Your task is to draw a hybrid topology (Bus and star) that will connect all the employee computers to the printer so that anyone can use it when needed.

B. Briefly explain baseline wandering and lack of self-synchronization problem.

C. Why do we need scrambling and block coding?

D. Identify the line coding schemes based on the requirements and convert this data: 1011110010100 according to those schemes

a. High bandwidth requirement but no DC component and self synchronization problem.

b. Good bandwidth utilization, no DC component problem but has a self synchronization problem.

c. Good bandwidth utilization, no baseline wandering, dc component and self synchronization problem.
