Answer:

C. Decreased drastically over the last five decades.

Explanation:

The cost of a given amount of computing power has decreased drastically over the last five decades. This can be proven beyond reasonable doubts with the invention of smartphones. Overtime, smartphones have become less expensive for a certain amount of computing power and easy to use.

Contrary to what was obtainable in the past where we have the large-scale Vacuum tube UNIVAC computers, ENIAC and the IBM series for computing. They weren't only big in size, they had a very small processing speed and very expensive too.

Smartphones has by far outlived the above-mentioned devices in all ramifications owing to the fact that it's relatively cheap, small in size, high processor speed and larger storage space.

Answer:

decreased drastically over the last five decades

Explanation:

I would say it is that answer because a few decades ago we needed huuuge computers that filled rooms to compute simple tasks. Now we have cellphones, which are basically computers that can fit into the palm of our hands. Our phones can do more than what those huge computers of the past did and they're easier to produce. So cost must have drastically decreased.

Byte pair encoding is a data encoding technique. The encoding algorithm looks for pairs of characters that appear in the string

nika2105 [10]

Answer:

The encoding algorithm looks for pairs of characters that appear in the string more than once and replaces each instance of that pair with a corresponding character that does not appear in the string. ... Byte pair encoding is an example of a lossy transformation because it discards some of the data in the original string.

NARA [144]

Answer:

AspNet.ScriptManager.jQuery?

Explanation:

Unobtrusive validation means we can perform a simple client-side validation without writing a lot of validation code by adding suitable attributes and also by including the suitable script files.

One of the benefits of using a unobtrusive validation is that it help to reduce the amount of the Java script that is generated. We can install the AspNet.ScriptManager.jQuery? for the unobtrusive validation.

When the unobtrusive validation is used, validation of the client is being performed by using a JavaScript library.

Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that

zalisa [80]

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

int[] array = new int[10];

int index = 0;

while(index < array.size()){

int number = (rand() % 100) + 1;

for (int i = 0; i < 1; i++) {

array[index] = number;

cout<< "Position "<< index << "of the array = "<< number << endl;

++index;

}

Explanation:

The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
