Cloud Computing technologies

A) Select an organization that has leveraged Cloud Computing technologies to improve profitability or to give them a competitive advantage.  

B) Research the organization to understand the challenges that they faced and how they intended to use Cloud Computing to overcome their challenges.  

The paper should include the following sections each called out with a header.

1) Company Overview:  The section should include the company name, the industry they are in and a general overview of the organization.

2) Challenges: Discuss the challenges the organization had that limited their profitability and/or competitiveness and how they planned to leverage Cloud Computing to overcome their challenges.

3) Solution:  Describe the organization’s Cloud Computing implementation and the benefits they realized from the implementation.  What was the result of implementing Cloud Computing?  Did they meet their objectives for fall short?

4) Conclusion:  Summarize the most important ideas from the paper and make recommendations or how they might have achieved even greater success.

Requirements:

Question 8 part (c)

Layer1, that is, physical layer and layer 2, that is, data link layer are common to USB2 and USB 3.

Layer 1 is the Physical Layer. This Layer includes Fiber, Twisted Pair (copper), Serial, USB, coaxial and others. In other words, interface connections and cabling. Some of those physical connections will be defined by the color of the cable: for fiber, Single Mode cable will be typically yellow and Multi Mode cable typically Orange. The fiber transceivers themselves are available in different kinds of connectors: SC, ST, LC. Serial interfaces are defined by cable types—two wire, four wire; USB interfaces fall into 3 categories of support and thus, identified as 1.1, 2.0 or 3.0; each having a different capability. Twisted pair cabling is available in CAT3 all the way up to CAT7, available in cross over or straight through, as well as whether it is shielded or unshielded.

Layer 2 is the Data Link Layer. The Data Link Layer covers how the data is transmitted over the Physical Layer 1. It packages raw bits from the physical layer into frames (logical, structured packets for data). It is protocol layer responsible for transferring frames from one node to another in a LAN or between network nodes in a WAN. Simply put, Layer 2 provides data transfer across the physical link. But the data link layer is also divided into two sub-layers: the MAC (Media Access Control) layer and the LLC (Logical Link Control) layer. The former controls how computers on the network gain access to the data and obtain permission to transmit it; the latter controls packet synchronization, flow control and error checking.

Assignment Description

Assignment Details

For this project, you will write a Java program that demonstrates exception handling. To facilitate this, you will need to collect input from a user, perform calculations, and send output to the screen. Exception handling will catch any input and calculation errors that may arise. For this project you will need the following variables (all integers): Three to store the input from the user, one to store the sum, and one to store the total. Remember to set their initial values to zero.

Create a new Java project. Write code to prompt the user to enter a number, then repeat this for a second number and a third. As each number is entered, store it in a variable. In each case, use an Input Mismatch Exception handler to catch when the user enters a letter instead of a number. Use the Catch block to inform the user that they should only enter numbers.

When all three numbers have been stored in variables, add the three numbers (their variables) together and store the sum in another variable.

Next, calculate a total that equals the sum of the three variables divided by the third input variable. (Put another way, divide the sum of the numbers by the third number that the user entered.) Use an Arithmetic Exception to handle situations where the third number that was entered by the user was a zero, informing the user that the program has produced a “Divide by zero error.”

Document your code thoroughly with code comments and be sure to explain how each exception works and what it is doing.

Tip: No custom classes, loops, or IF/ELSE statements are needed for this assignment.
Tip: Remember to initialize your variables!
