Explanation:
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]

O D. Ask if you have to give a slide presentation.
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.

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.

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 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 cache. (a) How many paths does the function foo of this program have
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.
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

If an object someThing has a method someMethod( ), then you can call the method using the statement ____________ .
a. someMethod(someThing);
b. someThing.someMethod( );
c. someMethod.someThing() ;
d. someThing = someMethod( );
Answer:
C) someThing.someMethod( )
Explanation:
The methods in a class can be accessed outside the class (assuming they are public methods and not private to the class) by using the dot(.) symbol and calling the method on the instance or object of the class.
In this case, the object of the class someThing, calls the method, someMethod( ) by using a dot and the name of the method with a parentheses at the end. This enables the code in the method act on the class instance or object.
