What file system was installed on the hard drive, how many volume?
Which operating system was installed on the computer?
How many user accounts existed on the computer?
Which computer did this image come from? Any indicator that it's a VM?
What actions did you take to analyze the artifacts you have found in the image/computer? (While many files in computer are irrelevant to case, how did you search for an artifacts/interesting files in the huge pile of files?
Can you describe the backgrounds of the people who used the computer? For example, Internet surfing habits, potential employers, known associates, etc.
If there is any evidence related to the theft of gun? Why do you think so?
a. Possibly Who was involved? Where do they live?
b. Possible dates associated with the thefts?
Are there any files related to this crime or another potential crime? Why did you think they are potential artifacts? What type of files are those? Any hidden file? Any Hidden data?

Assume a 2^20 byte memory:
a) What are the lowest and highest addresses if memory is byte-addressable?
b) What are the lowest and highest addresses if memory is word-addressable, assuming a 16-bit word?
c) What are the lowest and highest addresses if memory is word-addressable, assuming a 32-bit word?
a) Lowest address: 0, Highest address: (2^20) - 1. b) Lowest address: 0, Highest address: ((2^20) / 2) - 1. c) Lowest address: 0, Highest address: ((2^20) / 4) - 1.
a) If memory is byte-addressable, the lowest address would be 0 and the highest address would be (2^20) - 1.
This is because each byte in the memory requires a unique address, and since there are 2^20 bytes in total, the highest address would be one less than the total number of bytes.
b) If memory is word-addressable with a 16-bit word, each word would consist of 2 bytes.
Therefore, the lowest address would be 0 (representing the first word), and the highest address would be ((2^20) / 2) - 1.
This is because the total number of words is equal to the total number of bytes divided by 2.
Subtracting 1 gives us the highest address, as the addresses are zero-based.
c) If memory is word-addressable with a 32-bit word, each word would consist of 4 bytes.
In this case, the lowest address would still be 0 (representing the first word), and the highest address would be ((2^20) / 4) - 1.
Similar to the previous case, the total number of words is equal to the total number of bytes divided by 4.
Subtracting 1 gives us the highest address.

3% 7
7 % 3
17 % 7
11 % 7
28 % 7
Answer:
3% 7
Explanation:
because 7 because seven ate nine and three was lonely so seven decided to also eat three and became a lesser number somehow because three apparently was not as big as the number 9 so maybe eating three caused him to go down to 4
The expression "11 % 7" in Java is equal to 4.
The "%" operator calculates the remainder of a division operation.
In Java, the "%" operator is used to calculate the remainder of a division operation.
So, let's evaluate each expression and see which ones equal 4:
3 % 7 = 3 (remainder of dividing 3 by 7)
7 % 3 = 1 (remainder of dividing 7 by 3)
17 % 7 = 3 (remainder of dividing 17 by 7)
11 % 7 = 4 (remainder of dividing 11 by 7)
28 % 7 = 0 (remainder of dividing 28 by 7)
Based on these evaluations, the expression "11 % 7" is equal to 4.

III.

while (pos < vals.length)
{
total += vals[pos];
pos++;
}
I only
II only
I and III
II and III
III only
Answer:
I and III
Explanation:
We need a solution that iterates through the each item in the vals array and sums them (cumulative sum). The result should be held in total.
I:
This one uses enhanced for loop (i refers to the each value in vals) and sums the values.
II:
This one uses for loop, but the loop is not constructed well. The control variable of the loop, pos, initially set the length of the vals and the loop iterates while pos is greater than 0. If vals have 10, 20, 30 as values, the length would be 3. In this case, vals[pos] when pos is 3, would give us an error because last index would be 2 in that scenario. Also, you can't access the first value because loop will stop when pos is 0.
III:
This one uses a while loop and iterates each value in the vals and sums them. Note that in this case, the values pos have will be 0, 1, 2 ..., length-1 - which are valid to access each item.

The following code achieves the task of adding commas and apostrophes, therefore splitting names in the list. However, in the case where both first and last names are given how would I "tell"/write a code that understands the last name and doesn't split them both. For example 'Jack Hansen' as a whole, rather than 'Jack' 'Hansen'.
names = "Jack Tomas Ponce Ana Mike Jenny"
newList = list(map(str, names.split()))
print(newList) #now the new list has comma, and apostrophe
Answer:
You can use regular expressions to match patterns in the names and split them accordingly. One way to do this is to use the re.split() function, which allows you to split a string based on a regular expression.
For example, you can use the regular expression (?<=[A-Z])\s(?=[A-Z]) to match a space between two capital letters, indicating a first and last name. Then use the re.split() function to split the names based on this regular expression.
Here is an example of how you can use this approach to split the names in your list:
(Picture attached)
This will give you the output ['Jack', 'Tomas', 'Ponce', 'Ana', 'Mike', 'Jenny', 'Jack Hansen']. As you can see, the name "Jack Hansen" is not split, as it matches the pattern of first and last name.
It's worth noting that this approach assumes that all first and last names will have the first letter capitalized and the last names capitalized too. If this is not the case in your data, you may need to adjust the regular expression accordingly.

Why Is Microsoft software so dominant in the business world?
In recent years there has been a trend to represent traditional relational data in a semi structured data format such as XML.
a) List and explain three of the main motivations for this trend over recent years.
b) State an application and explain why the stated application warrants the need to store and process semi-structured data.
c) Explain the support required for storing semi-structured data in a relational database
d) Discuss the performance implications for retrieving a particular XML element from a XML file.
(Advanced Database Systems Course)
a) Three main motivations for representing traditional relational data in a semi-structured data format such as XML in recent years include:
Flexibility: XML is a flexible data format that allows for the representation of complex data structures, such as hierarchical or nested relationships, that are difficult to represent in a traditional tabular format.Interoperability: XML is a widely-supported data format that is used by many different systems and applications, making it easy to exchange data between different platforms.Extensibility: XML allows for the creation of custom tags and attributes, making it easy to add new information to a data structure without changing its overall structure.What are the others about?b) One application that warrants the need to store and process semi-structured data is a content management system (CMS). A CMS is a system used to create, edit, and manage digital content, such as websites or online documents. Because digital content can be highly varied and complex, a CMS must be able to handle a wide range of data types and structures. Using a semi-structured data format like XML allows a CMS to represent and manage this complex data in a flexible and extensible way.
c) In order to store semi-structured data in a relational database, the database must have support for storing and manipulating XML data. This may involve adding specific data types for storing XML documents or elements, as well as supporting functions and operators for querying and manipulating XML data.
Lastly d) Retrieving a particular XML element from a XML file can have performance implications, especially if the file is large or the element is deeply nested within the file's structure. To optimize performance, it may be necessary to index the XML data in order to speed up element retrieval, or to use specialized XML processing tools that are optimized for this task. Additionally, the use of a database system that has built-in support for handling XML data can also help to improve performance when working with semi-structured data.
