A web browser translates web language code into the content we interact with on a website. It communicates with the server to receive website data in packets and interprets the various codes to present the multimedia content of websites seamlessly.

Explanation:

When you access a website, your web browser translates web language code into words, graphics, and videos. Websites are multimodal texts that not only include text but also a combination of other elements such as images, sounds, and animation to deliver content. The browser plays a crucial role in this process.

As part of the internet's functionality, when you request to view a website, your browser sends a message to the website's server. The server then responds by sending the website's contents back to your browser in the form of traffic, which is broken down into packets. Each packet contains the website's data along with the location it needs to reach.

Cloud computing refers to files and services, that are processed to retrieved over all the computers, rather than on the hard disk of your machine. It's also known as a Net metaphor, which is a so-called local disc and device, whenever you store information on a disc or run programs.

Final answer:

Organizations using cloud computing can indeed save on the expense of purchasing and maintaining hardware. Cloud services offer scalable resources and potential cost savings, but are not always the cheaper option and businesses should conduct a cost/benefit analysis.

Explanation:

Cloud Computing and Cost Savings

It is true that when an organization uses cloud computing, they do not have to buy and maintain expensive hardware. This advantage is particularly significant for new organizations that have not yet invested in their own IT environments. Leveraging cloud services means that companies pay only for the capacity and resources they actually utilize rather than shouldering the cost for peak load capacity that remains idle most of the time. Moreover, subscribers to cloud services benefit from the economies of scale that vendors achieve by sharing resources across multiple customers. However, it's important to note that cloud services are not always cheaper and organizations must do a careful cost/benefit analysis, as some, like Foursquare, have found it more economical to run their own hardware.

The order to use the Paste Special function is 1, 5, 2, 4, 3

Explanation:

The Paste Special function is used to copy the contents of the cell without the properties of that cell.

For example, if a cell contains the text "my room" and it is colored pink, and also has a background color of black and other properties, and you want to copy just the text to another cell, copying and pasting normally (that is, using Ctrl + C and Ctrl + V or clicking copy and paste from the home tab) will copy and paste the cell with its properties, but to copy just the text, you need to use the Paste Special function.

To use the Paste special function in Microsoft Excel:

Answer:

With the use of -h or -help switches.

Explanation:

Linux shell is a terminal in the Linux operating system that receives input or typed commands to perform an action based on the command. These commands are the same commands embedded in the icons of the graphic interface operating systems.

To get the kernel version of the Linux operating system in the command line prompt, the uname command among other useful commands can be used. To get help on how to use the command to get more information and more options, use the -h or -help switch next to the uname command.

Final answer:

Dustin can use the 'uname –a' command to display all system info or 'uname –r' to see just the kernel version. He should also consider system architecture when choosing binaries and use 'echo $0' to find out the current shell. Extensive online documentation and help systems provide further guidance.

Explanation:

To determine which kernel version the system is running, Dustin can use the uname command with the –a option in the command line. This option will provide all the information about the system, including the kernel version. If Dustin is specifically focused on the kernel, the uname –r command will give him the kernel version without the extra details.

Additionally, understanding the system architecture (32-bit vs 64-bit) is crucial when choosing the correct binaries to download and use, such as i86linux64 for a 64-bit GNU/Linux system. This knowledge combined with tools like wget allows users to download and install the correct software for their system. Should Dustin need more help, he can explore the detailed documentation available online or use the help system built into the command line.

Moreover, if he's operating on a non-Linux system like MacOS, he may need to search for compatible GNU core utils or consider using virtual machine software such as VirtualBox for a Linux distribution. It's also important to know which shell is in use, and Dustin can find this out by running echo $0 in the command line.

Call changeUS (x,y)

Display( x, " " ,y)

End module

The module 'getNumber' that uses a reference parameter variable to accept an Integer argument is given below.

We have,

A Python module named 'getNumber' that uses a reference parameter variable to accept an Integer argument:

def getNumber(number_ref):

   try:

       number = int(input("Enter a number: "))

       number_ref[0] = number

   except ValueError:

       print("Invalid input. Please enter a valid integer.")

# Example usage:

# num = [0]  # Create a list to store the reference to the number

# getNumber(num)  # Call the module and pass the reference

# print("The entered number is:", num[0])  # Access the number using the reference

Now,

In this module, we use a list (number_ref) as the reference parameter to accept an Integer argument.

The user is prompted to enter a number, and the input is then stored in the reference parameter variable, which allows us to modify the original value of the variable outside the function scope.

Thus,

The module 'getNumber' that uses a reference parameter variable to accept an Integer argument is given above.

Final answer:

With the violation mode set to restrict on a switch port, a syslog message is generated, and the violation counter is incremented by 1 when a frame violates the port security policy. The port does not go into an err-disabled state and non-violating traffic passes through normally.

Explanation:

When a switch port configured with port security receives a frame that violates the configured security policy, the behavior of the port depends on the violation mode set. In the case where the violation mode is set to restrict, the following occurs:

Given the available options, the correct answers to what happens when a frame violating the port security policy enters the interface are:

The second frame that does not violate the policy will be forwarded normally, as the port does not become err-disabled and the frame does not contribute to a policy violation.

Answer:

1. Capacitive load for pentium 4 prescott processor = 32 nF. Capacitive load for core i5 ivy processor = 29.05 nF

2. Percentage of total dissipated power comprised by static power for Pentium 4 Prescott processor = 10 %. The ratio of static power to dynamic power = 0.11

Percentage of total dissipated power comprised by static power for Core i5 Ivy Bridge processor = 42.86 %. The ratio of static power to dynamic power = 0.75

3. Reduction in voltage for Pentium 4 Prescott processor = 5.9 % reduction

Reduction in voltage for Core i5 Ivy Bridge processor = 9.8 % reduction

Explanation:

1. We know that dynamic power, P ≈ 1/2 CV²f where C is the capacitive load of the transistor, v its voltage and f the frequency.

So C ≈ 2P/V²f

For the Pentium 4 Prescott processor, V₁ = 1.25 V, f₁ = 3.6 GHz and P₁ = 90 W. Let C₁ be its capacitive load. So, C₁ ≈ 2P/V²f = 2 × 90 W/ (1.25 V)² × 3.6 × 10⁹ Hz = 3.2 × 10⁻⁸ F = 32 × 10⁻⁹ F = 32 nF

For the Core i% Ivy Bridge processor, V = 0.9 V, f = 3.4 GHz and P = 40 W. Let C₂ be its capacitive load. So, C₂ ≈ 2P/V²f = 2 × 40 W/ (0.9 V)² × 3.4 × 10⁹ Hz = 2.905 × 10⁻⁸ F = 29.05 × 10⁻⁹ F = 29.05 nF

2. Total power = static power + dynamic power.

For the Pentium 4 Prescott processor, static power = 10 W and dynamic power = 90 W. So, total power, P = 10 W + 90 W = 100 W.

The percentage of this total power that is static power = static power/total power × 100 = 10/100 × 100 = 10 %

The ratio of static power to dynamic power = static power/ dynamic power = 10/90 = 0.11

For the Core i5 Ivy Bridge processor, static power = 30 W and dynamic power = 40 W. So, total power, P = 30 W + 40 W = 70 W.

The percentage of this total power that is static power = static power/total power × 100 = 30/70 × 100 = 42.86 %

The ratio of static power to dynamic power = static power/ dynamic power = 30/40 = 0.75

3. We know Total power = static power + dynamic power. And that leakage current is due to static power. Since P = IV , I (leakage current) = P/ V

Since the total dissipated power is reduced by 10%, P₂ = (1 - 0.1)P₁ = 0.9P₁ where P₁ is the total power dissipated before the 10% reduction and P₂ is the new power dissipated after the 10% reduction in total dissipated power.

Let new total dissipated power, P₂ = new static power I₂V₂ + new dynamic power 1/2C₂V₂²f₂  = 0.9P₁.

For the Pentium 4 Prescott processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁. Since I₂(leakage current) = static power/voltage = 10 W/1.25 V = 8 A (since the leakage current is constant), we have

8 A × V₂ + 1/2 × 32 × 10⁻⁹ F × V₂² × 3.6 × 10⁹ Hz = 0.9 × 100

8V₂ + 57.6V₂² = 90. This leads to the quadratic equation

57.6V₂² + 8V₂ - 90 = 0. By the quadratic formula,

V₂ = [tex]\frac{-8 +/- \sqrt{8^{2} -4X57.6 X -90} }{2X57.6} = \frac{-8 +/- \sqrt{64 + 20736} }{115.2} = \frac{-8 +/- \sqrt{20800} }{115.2}\\=\frac{-8 +/- 144.222}{115.2}\\[/tex]

V₂ = 1.18 V or - 1.32 V .

Choosing the positive answer, the new voltage is 1.18 V. The percentage reduction is (new voltage - old voltage)/new voltage × 100 % = (1.18 - 1.25)/1.18 × 100 % = -0.07/1.18 × 100 % = -5.9 % . Which is a 5.9 % reduction from 1.25 V

For the Core i5 Ivy Bridge processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁. Since I₂(leakage current) = static power/voltage = 30 W/0.9 V = 33.33 A (since the leakage current is constant), we have

33.33 A × V₂ + 1/2 × 29.05 × 10⁻⁹ F × V₂² × 3.4 × 10⁹ Hz = 0.9 × 70

33.33V₂ + 49.385V₂² = 63. This leads to the quadratic equation

49.385V₂² + 33.33V₂ - 63 = 0. By the quadratic formula,

V₂ = [tex]\frac{-49.385 +/- \sqrt{49.385^{2} -4X33.33 X -63} }{2X33.33} = \frac{-49.385 +/- \sqrt{2438.8782 + 8399.916} }{66.66} = \frac{-49.385 +/- \sqrt{10838.794} }{66.66}\\=\frac{-49.385 +/- 104.110}{66.66}\\[/tex]

V₂ = 0.82 V or - 2.30 V .

Choosing the positive answer, the new voltage is 0.82 V. The percentage reduction is (new voltage - old voltage)/new voltage × 100 % = (0.82 - 0.9)/0.82 × 100 % = -0.08/0.82 × 100 % = -9.8 % . Which is a 9.8 % reduction from 0.9 V

                                      After that  So C ≈ 2P/V²f

So that is For the Core i% Ivy Bridge processor, V = 0.9 V, f = 3.4 GHz and also P = 40 W. Let C₂ the capacitive load. So, C₂ ≈ 2P/V²f = 2 × 40 W/ (0.9 V)² × 3.4 × 10⁹ Hz = 2.905 × 10⁻⁸ F = 29.05 × 10⁻⁹ F = 29.05 nF

The next step will be Total power that is = static power + dynamic power.

8 A × V₂ + 1/2 × 32 × 10⁻⁹ F × V₂² × 3.6 × 10⁹ Hz = 0.9 × 100

8V₂ + 57.6V₂² = 90. This leads to the quadratic equation  

57.6V₂² + 8V₂ - 90 = 0. By the quadratic formula, V₂ =  

V₂ = 1.18 V that is - 1.32 V .

33.33 A × V₂ + 1/2 × 29.05 × 10⁻⁹ F × V₂² × 3.4 × 10⁹ Hz = 0.9 × 70

33.33V₂ + 49.385V₂² = 63. This leads to the quadratic equation

49.385V₂² + 33.33V₂ - 63 = 0. By the quadratic formula, V₂ =

V₂ = 0.82 V that is - 2.30 V .
