Assume the clock for a 4-bit binary counter is 80 kHz. The output frequency of the fourth stage (Q3) is
Answer:
5kHz
Explanation:
There are four stages so N = 2⁴ = 16.
The frequency at nth stage is given by
[tex]f_n = \frac{f_{clk}}{N} = \frac{80kHz}{16} = 5kHz[/tex]
The output frequency of the fourth stage (Q3) is 5kHz. Thus the correct option is A.
What is a 4-bit binary counter?On each clock cycle, the 4-bit synchronous counter successively counts up from 0 (0000) to 15 as outputs ( 1111 ). It is also known as a 4-bit Synchronous Up Counter as result.
We required four Flip Flops to create a 4-bit counter, as indicated by the number 4 Flip Flops. The counter also has a reset pin, which enables it to enter an all-zero mode in which its output is "0."
The Q output of the previous flip-flop triggers the CLK input in the 4-bit counter above, as opposed to the Q output as in the up counter configuration, where the output of each flip-flop changes state on the rising edge.
There are four stages so N = 2⁴ = 16.
The 4-bit binary counter is 80 kHz.
In order to calculate the output frequency the 4-bit binary counter is divided by 16 which is equal to 5kHz.
Therefore, option A is appropriate.

Why are people's visions of utopias and dystopias subjective?
A. Because the vision one person has of paradise will likely match
the vision most people have of a utopia
B. Because only certain technologies make things better and
different ones make things worse in a dystopia
C. Because all technology is dangerous and can lead to the downfall
of all societies, resulting in dystopia
D. Because the technology needed for one person's utopia may be
what creates disaster for another person's dystopia
Answer:
D. Because the technology needed for one person's utopia may be what creates disaster for another person's dystopia.
Explanation:
Because the technology needed for one person's utopia may be what creates disaster for another person's dystopia are people's visions of utopias and dystopias subjective. Thus option D is correct.
What are utopias and dystopias?Speculative fiction categories that study social as well as political structures include utopian and dystopian literature. In order to pique readers' interest, utopian fiction often depicts a world that adheres to the author's ethics and has many elements of a different reality.
Ultimately, it all varies depending on who you ask. A person's dystopia may be another person's utopia. We don't all have the same notions regarding what a utopia would look like, which is, in my opinion, one of the grounds why people don't live in one. Therefore, option D is the correct option.

g A CPU is equipped with a cache; Accessing a word takes 20 clock cycles if the data is not in the cache and 5 clock cycles if the data is in the cache. What is the effective memory access time in clock cycles if the hit ratio is 90%
Answer:
6.5
Explanation:
The formula to calculate the efficiency is;
= (cache-click-cycle x hit ratio) + ( memory-clock-cycle x 1 - hit ratio)
= (5 x 0.9) + ( 20 x 0.1)
= 4.5 + 2
= 6.5
In this exercise we have to use the knowledge of efficiency, in this way, using the data already informed, we can say that the result of this is:
6.5 effective memory
In this exercise, it was informed that some conditions must be established, that is:
Hit radio: 90%Memory: 20Cache: 5
The formula to calculate the efficiency is;
[tex]efficiency= ((cache-click-cycle)(hit \ ratio)) + ( (memory-clock-cycle)(1 - hit \ ratio))[/tex]
Substituting the known values in the formula above, we find that:
[tex]= (5)(0.9) + ( 20)(0.1)\\= 4.5 + 2\\= 6.5[/tex]

Which important aspect of the Roman Empire did the barbarians destroy?
Answer:
centers of learning
Explanation:
Under the leadership of Emperor Valens, Rome was already having financial hardships. This meant that it didn't have enough money left to repair its empire nor to strengthen it against invaders. Soon, the barbarians such as the Franks, Huns, Saxons, etc. started attacking Rome. They spent a lot of time destroying the outer regions of the empire because they were also at war with each other. They penetrated Rome and it soon fell. The barbarians didn't only destroy the cities but they also destroyed the "centers of learning." Roman people were known to value education. With the fall of the Roman Empire, so did education and sophisticated architectures follow.

The Bellman-Ford algorithm for the shortest path problem with negative edge weights will report that there exists a negative cycle if at least one edge can still be relaxed after performing nm times of relaxations. The algorithm, however, does not specify which cycle is a negative cycle. Design an algorithm to report one such cycle if it exists. You should make your algorithm runs as fast as possible.
Answer:
- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.
- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".
- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.
- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.
Explanation:
The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.

>>> phrase = "You are amazing!"
>>> _____
'u a'
phrase[3:6]
phrase[2:6]
phrase[3:5]
phrase[2:5]
Answer:
phrase[2:5]
Explanation:
Given:
The above code segment
Required
Which instruction returns 'u a'
First, we need to get the index of u in the phrase:
u is at the third position but in programming, index starts at 0.
So, u is at index 2
Next, we need to get the index of a in the phrase:
a is at index 4
One of the ways to return a sub string from a string in python is [tex]string[start:stop+1][/tex]
Where:
[tex]start = 2[/tex] ----- index of u
[tex]stop = 4[/tex] ----- index of a
phrase ---- The string variable
So, the instruction that returns 'u a' is: [tex]phrase[2:5][/tex]
Where 5 = 4 + 1
Answer:
phrase[2:5]

Suppose that a t-shirt comes in five sizes: S, M, L, XL, XXL. Each size comes in four colors. How many possible t-shirts are there?
Answer:
120
Explanation:
This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.
5 permutation of 4
To find permutation, we use the formula
P(n, r) = n! / (n - r)!
Where
n is the size of the shirts available, 5
r is the color of each shirt available, 4
P(5, 4) = 5! / (5 - 4)!
P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!
P(5, 4) = 120 / 1
P(5, 4) = 120
Therefore, the total number of shirts available is 120
