Fantom [35]

Answer:

Outline the steps necessary to prepare a storage device for storing files.

Link the storage unit to a network, whether it be a laptop computer or a mobile device.
Firewall it with sufficient anti-virus so that it also does not affect the linked system.
The program must auto-install the storage device on the network after quarantine, and authorize it.
Test the file that requires to be moved to the storage device, then upload it to the storage device after anti virus is safe.
Should not directly pull the storage device out of the network, select the exit device option correctly and only then remove the device after it has been accepted.

Identify and briefly describe the tools used to prepare a storage device for storing files.

EFSDump - Users can share encrypted files by carrying certificates by using EFSDump. It is usually very time consuming to audit the users who have privileges. But it is very simple to list users who have access to encrypted files using EFSDump.

SDelete - Suppose Windows operating system eliminates the index and prevents access when we delete a file. All the same, attackers can still recover the contents of the file. Files that are encrypted by EFS leave the file behind on the disk. Using the SDelete tool we can modify free space to prevent the recovery of deleted files.

Explain why file systems are critical components of an operating system. What is their purpose?

Hypothetically defining file system is nothing more than the way files are called and logically organized for storage.

Ex: DOS, Windows, and Unix-based operating systems all contain various file systems where data is organized in tree structure.

Usually defines the naming of files, how long the suffix can be. The file system often includes a format indicating the access to a file.

Specify the file system or file systems that would be available with that operating system.

A file system controls the mechanism by which data is stored and accessed on a disk. This deals mainly with internal disk operations such as naming files, records, directories, documentation, storage management, and other protocol accesses.

FAT (File Allocation Table)
NTFS (New Technology File System)

Describe from an administrator perspective what is necessary to prepare a storage device for access by a user.

Connection to the storage unit is equipment-oriented. The Windows Explorer summary contains optical drives, USB keys and hard drives as separate devices, making it much easier to navigate a new computer.

To connect a Linux computer you must mount the drive by connecting it to a directory.

Usually mounting a device is a manual operation, since only the administrator determines which directory the system attaches to.

Graphical interfaces are seldom seen on Linux servers. When you plug a storage device into a USB port on your computer, nothing can happen.

Usually the mount command looks like mount/dev / sdb1/mnt, where /dev / sdb1 is the system and /mnt is the directory you want to mount it.

List a few ways that a user can utilize a file system.

System output can be improved not only by choosing the most appropriate file system(s) but also by using the various choices available for most file systems.

There are variations in the number of options depending on the specific file system, and some options can only be set at the time of development of the filesystem, even though it can be modified afterwards.

g Assume that this program is run on a processor with data cache of size big enough that the entire array arr can fit in the cac

Dimas [21]

Answer:

A. 2

Explanation:

The food function in the C source code uses two for loop statements to fill and array of size 100 with 100 values ranging from 1 to 100 and the second to get the total sum to the values in the array. With this, two program paths are created.

Which of the following lines correctly defines a String variable

lidiya [134]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is C i.e. String s = "apluse";

The rule or syntax of declaring string in any programming language is given below:

String variable-name = "yourString";

For declaring string variable, first, you write "String" that is a keyword of a programming languages for declaring string variables, such as int before the variable name for declaring integer variable. Then, you need to write a meaningful name of the string as a variable. After string variable name, you need to put the equal operator and then write the string in double quotation("") marks and after that put the instruction terminator that is ";".

So, according to this syntax, option C is correct.

While other options are not correct because:

In option a, string is not encapsulated in double quotation. Option B does not have varaible type such as String and Option E does not have variable name and its value also. So, only option C is correct and all other except C are incorrect.

Write a Python function LetterGame() that repeatedly asks the user to input a letter. The function is to count the number of vow

kotegsom [21]

Answer:

def LetterGame():

vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]

count1 = count2 = 0

while True:

choice = input("Enter a letter / digit to stop: ")

if choice.isdigit():

break

elif choice.isalpha():

count1 += 1

if choice in vowels:

count2 += 1

print("You entered " + str(count1) + " letters, " + str(count2) + " of which weere vowels.")

print("The percentage of vowels was " + str(count2 / count1 * 100) + "%")

LetterGame()

Explanation:

Create a function called LetterGame

Inside the function:

Create a list of vowels

Initialize count1, counts the total letters, and count2, counts the vowels

Initialize a while loop that iterates until the specified condition is met in the loop

Get the input from the user. If it is a digit, stop the loop. If it is an alphabet, increase the count1 by 1, and also check if it is a vowel. If it is a vowel, increment the count2 by 1

When the loop is done, print the required information

Finally, call the function

Assume that the final grade for a course is determined based on this scale - A: 900 points, B: 800-899 points, C: 700-799 points

saul85 [17]

Answer:

In Python:

def get_letter_grade(points):

if points>=900:

grade ="A"

elif points>=800 and points < 900:

grade ="B"

elif points>=700 and points < 800:

grade ="C"

elif points>=600 and points < 700:

grade ="D"

else:

grade = "F"

return grade

Explanation:

This defines the function

def get_letter_grade(points):

The following if-else if conditions check the score to determine the appropriate grade

if points>=900:

grade ="A"

elif points>=800 and points < 900:

grade ="B"

elif points>=700 and points < 800:

grade ="C"

elif points>=600 and points < 700:

grade ="D"

else:

grade = "F"

This returns the grade

return grade
