Question
Chapter 10, Problem 24SG
Program Plan Intro
Dedicated Line:
- Dedicated Line is defined as a physical connectivity between two communicating devices.
- Two types of dedicated lines are,
- Analog dedicated line
- Digital dedicated line
- Most of the time, home or business users are connected by digital dedicated line for faster communication.
Explanation of Solution
Types of Digital Dedicated Lines:
- Digital Subscriber Line (DSL.)
- DSL is a standard phone line that can carry only a single communication signal.
- It is used to carry both voice and data communications.
- DSL and voice communication use the same telephone line to transfer the information but in different frequency.
- Fiber to the Premises (FTTP)
- It uses fiber optic cables, which is used to provide high internet access to permanent location of users.
- It is also called as Fiber to the Home (FTTP)
- Fiber optic cables are made up of two or more optical fibers which are designed to carry light.
- Integrated Services Digital Network (ISDN)
- It uses the technique called multiplexing by which ISDN can carry there or more signals through a same line.
- The main feature of ISDN is that it integrates both speech and data in the same line.
- The usage of a set of signaling protocols are limited by ISDN.
- T-Carrier Line
- T-Carrier line is a long distance digital phone lines which carries multiple signals over a single communication line...

Suppose that the two Rank methods below are added to the Skip List class on Blackboard.
public int Rank(T item)
Returns the rank of the given item.
public T Rank(int i)
Returns the item with the given rank i.
Requirements
1. Describe in a separate Design Document what additional data is needed and how that data is used to
support an expected time complexity of O(log n) for each of the Rank methods. Show as well that the
methods Insert and Remove can efficiently maintain this data as items are inserted and removed. (7
marks)
2. Re-implement the methods Insert and Remove of the Skip List class to maintain the augmented data in
expected O(log n) time. Using the Contains method, ensure that added items are distinct. (6 marks)
3. Implement the two Rank methods. (8 marks)
4. Test your new methods thoroughly. Include your test cases and results in a Test Document. (4 marks)
Why do we need official standards for copper cable and fiber-optic cable? What happens without the standard?
