Program Plan Intro
Describing fundamental components of a telecommunications system.
Expert Solution & Answer
Explanation of Solution
The fundamental components of a telecommunication system are:
- Sending Unit
- Modem
- Transmission Media
- Receiving unit
Sending Unit: A sending unit can be a person, computer system, a terminal or another device which is responsible with sending the message. The message which is to be sent originates at this sending unit.
Modem: Modem is responsible with performing many tasks which include converting signal into different forms from one type to another. It can convert the analog signal to digital and vice-versa. Most of the time digital signals are generated by sending devices and converted to analog form for transmission through transmission media. This process is repeated in reverse at the receiver end.
Transmission media: Transmission media are used to transmit signal generated by modem from one location to another. There are various types of transmission media in use which differ from each other depending on various factors such as transmission speed, cost and bandwidth. Some of the commonly used transmission media are twisted pair cables, coaxial cables, and fiber-optic cables.
Receiving unit: Receiving unit is similar to sending unit. It can be a person, a computer system, a terminal or another device who receives the message or information sent by the sending unit.

Lab 07: Java Graphics
(Bonus lab)
In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to
implement the following:
➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a
Point (see java.awt.Point) in a PointCollection class (you need to build this).
о The points need to be represented by circles.
Below the drawing panel, you will need 5 buttons:
о
An input button to register your mouse to the drawing panel.
○
о
о
A show button to paint the points in your collection on the drawing panel.
A button to shift all the points to the left by 50 pixels.
The x position of the points is not allowed to go below zero.
Another button to shift all the points to the right 50 pixels.
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.…
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?

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. 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.
