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...

Students have asked these similar questions
If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.
