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.

What is the value of X when line 30 is executed in the program below:
10 X = 5
20 X = X + 5
30 X = X/5 + X
40 X = X * 5
50 X = (X - 5)/5
this is for qbasic btw
any helpis appreciated pls only correct answers
Answer:
X = 12
Explanation:
The primary value of X is 5. In line 20 X = X + 5, which is saying the primary value of X ,5, + 5, this is going to return the value of X to now become 10. Now the primary value of X in the program has changed to 10.
In line 30 X = X/5 + X, keeping in mind that the new primary value is not 5 but 10. So now line 30 is saying X = 10/5 + 10. This return the value of X to be 12.
Fritz is a big fan of the racerville rockets. unfortunate;y, the team has been accused of cheating during their games. Fritz reads many articles and posts about this developing news story. His social media algorithms have "learned" that he's a fan of the team, so his feed doesnt show him any articles that argue the accusations are true. From this, Fritz decides his favorite team must be innocent of all cheating charges. Fritz is now in
A. a filter bubble
B. A third party
C. A subculture
D. an echo chamber
Option(D) is the correct answer. Fritz is now in an echo chamber.
Fritz's situation aligns with the concept of an echo chamber. An echo chamber refers to an environment, such as social media, where individuals are exposed to information and opinions that reinforce their existing beliefs and perspectives.
In this case, Fritz's social media algorithms have filtered out articles that present arguments in favor of the cheating accusations, creating an echo chamber that only confirms his preconceived notion of the team's innocence.
As a result, Fritz is insulated from diverse viewpoints and alternative perspectives, which can hinder critical thinking and a comprehensive understanding of the situation.

Let n be the number of digits of the whole number. What is the number of operations that are executed in the code in terms of n?
Answer:
Following are the solution to this question:
Explanation:
Its complexity of both the pseudo-code described is indeed proportional to the number of digits. So, how often number there are in this specific number is the query. Whenever a number is considered, the d digit would be between \(10^{(d-1)}.\) inclusive exclusive \(10^d\) That would be as, let d become the number of digits at N, and the inequalities, They can tell
\(10^{(d-1)} \leq N < 10^d\)
We get, we take a logarithm,
\(d-1 \leq \log(N) < d\)
The increase of 1 to the left inequality, \(d \leq \log(N)+1\), and Combining the previous outcome, we got, \(\log(N) < d \leq \log(N) + 1\). That's would be to say, that number of number d by \(O(\log(N))\) is higher and lower. Consequently, the number of transactions in the code is \(O(\log(N))\)
We have that the number of operations that are executed in the code in terms of n is mathematically given as
The quantity of operations done in the code is O(log(N))
Operation
Generally the equation for the is mathematically given as
If we think about a number,
with d digits is between 10^(d-1) inclusive and 10^d exclusive.
Let d be the wide variety of digits in N
10^(d-1) <= N < 10^d
d-1 <= log(N) < d
d <= log(N) + 1,
The Inequality
log(N) < d <= log(N) + 1.
Therefore
The quantity of operations done in the code is O(log(N))

What is one way a lender can collect on a debt when the borrower defaults?
Answer:
When a borrower defaults on a debt, the lender may have several options for collecting on the debt. One way a lender can collect on a debt when the borrower defaults is by suing the borrower in court. If the lender is successful in court, they may be able to obtain a judgment against the borrower, which allows them to garnish the borrower's wages or seize their assets in order to pay off the debt.
Another way a lender can collect on a debt when the borrower defaults is by using a debt collection agency. Debt collection agencies are companies that specialize in recovering unpaid debts on behalf of lenders or creditors. Debt collection agencies may use a variety of tactics to try to collect on a debt, including contacting the borrower by phone, mail, or email, or even suing the borrower in court.
Finally, a lender may also be able to collect on a debt when the borrower defaults by repossessing any collateral that was pledged as security for the debt. For example, if the borrower defaulted on a car loan, the lender may be able to repossess the car and sell it in order to recover the unpaid balance on the loan.

Which option would allow you to watch an HD video, without delays in playback, on a computer with a Mac OS and a connection that has a lower bit rate? MPG QuickTime H.264 Flash Player
Answer:
H.264
Explanation:
A file type can be defined as the standard used to store digital data such as pictures, texts, videos, and audios. They all have unique file extension which determines the type of software program (application) to be used for opening a particular file and accessing its data e.g pictures (jpeg, png), texts (txt, docx, rtf), audios (mp3, acc), and videos (mp4, 3gp, avi, h.264, mkv).
Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.
H.265 is a high efficiency video codec (HEVC) and it's a standard video compression codec designed and developed to offer a better data compression, as an upgrade to the advanced video coding (AVC) standard.
Hence, the option or file extension (format) which would allow you to watch a high definition (HD) video, without delays in playback, on a computer with a Mac operating system (OS) and a connection that has a lower bit rate is the H.264 format.
