Answer: B. Perform a hash on the file for comparison with the vendor’s hash.

Explanation:

Before installing the firmware update, the step that the technician should perform to ensure file integrity is to perform a hash on the file for comparison with the vendor’s hash.

Hashing refers to the algorithm that is used for the calculation of a string value from a file. Hashes are helpful in the identification of a threat on a machine and when a user wants to query the network for the existence of a certain file.

Using C#, declare two variables of type string and assign them a value "The "use" of quotations causes difficulties." (without t
stich3 [128]

Answer:

Let the two string type variables be var1 and var2.  The value stored in these two variables is : The "use" of quotations causes difficulties.

  • The variable which uses quoted string:

          string var1 = "The \"use\" of quotations causes difficulties.";  

  • The variable which does not use quoted string:

string var2 = "The " + '\u0022' + "use" + '\u0022' + " of quotations causes difficulties.";

  • Another way of assigning this value to the variable without using quoted string is to define a constant for the quotation marks:

const string quotation_mark = "\"";

string var2 = "The " + quotation_mark + "use" + quotation_mark + " of quotations causes difficulties.";

Explanation:

In order to print and view the output of the above statements WriteLine() method of the Console class can be used.

   Console.WriteLine(var1);

   Console.WriteLine(var2);

In the first statement escape sequence \" is used in order to print: The "use" of quotations causes difficulties. This escape sequence is used to insert two quotation marks in the string like that used in the beginning and end of the word use.

In the second statement '\u0022' is used as an alternative to the quoted string which is the Unicode character used for a quotation mark.

In the third statement a constant named  quotation_mark is defined for quotation mark and is then used at each side of the use word to display it in double quotations in the output.

marishachu [46]

The subnet mask can be utilized to segment the 172.16.0.0 network to qualify for a minimum of 6 subnets while maximizing the numeral of broadcasters per subnet is 255.255.224.0

<h3>What do subnet masks mean?</h3>
  • A subnet mask is a 32-bit numeral formed by setting keeper bits to all 0s and developing network times to all 1s.
  • In this way, the subnet mask divides the IP speech into the network and host addresses.
  • A subnet mask is used to separate an IP address into two pieces. One element defines the host (computer), and the different part identifies the network to which it belongs.
  • To better comprehend how IP lessons and subnet masks work, look at an IP speech and see how it's managed.

To learn more about  subnet mask, refer to:

Answer:

UI Character Presets

Explanation:

User Interface is an option or go-to menu in a desktop application. For example, Photoshop. It allows a user to tweak the outlook to his or her own preference rather than the default settings.

To do this, a user is often tasked to do the following:

1. Click on the "Edit" menu

2. Navigate and click on "Preferences"

3. Select the "Interface" link

The options available to change includes:

a. UI Scaling

b. UI Font Size

c. UI Language.

Hence, in this case, the element that is not a selection in the Interface preferences is "UI Character preset"
