The doubling of the power of microprocessor technology while the costs of its production decreases by half is called ______ Law.
Answer:
The doubling of the power of microprocessor technology while the costs of its production decreases by half is called Moore's Law.
Explanation:
The Moore's Law was a law derived from a projection on historical trend of the number of transistors in integrated circuits rather than a statement based on laws of Physics. This law stated originally that the number of transistors in an integrated circuit doubles whereas production costs halves due to gain in manufacturing and design experiences every two years. This empirical law was formulated in 1.965.
Microprocessors are IC-based.
The complete answer is: The doubling of the power of microprocessor technology while the costs of its production decreases by half is called Moore's Law.
Question 1:
The Wayfinder is an ancient piece of technology created as a means of navigating challenging stretches of space. The device connects to every piece of technology in the galaxy in order to detect planets and spaceships and then shown their location to the user. As it happens, locations of planets follow a specific distribution. A planet can exist at coordinates x,y only if
2x² + |2xy| + y² =10000
The user can use the Wayfinder to find nearby planets by input the range for x and y. Draw a flowchart and write a C++ program that models the Wayfinder. Ask the user to input a range for x and y, then print all possible planet coordinates. The program should also print the number of planets detected.
Hint: you can use pow(x,n) to get the value of xn and abs(x) to get the absolute value of x.

Sample output:
Answer:
Following are the code to the given question:
#include<iostream>//header file
#include<math.h>//header file
using namespace std;
int main()//main method
{
long long x, x1, y, y1;//defining long variable
int count=0,i,j;//defining integer variable
cout<<"Enter a range for x coordinates: "<<endl;//print message
cin>>x>>x1;//input x and x1 value
cout<<"Enter a range for y coordinates: "<<endl;//print message
cin>>y>>y1; //input y and y1 value
for(i = x; i <= -x1; i++)//use nested loop that tests each coordinates
{
for(j = y; j <= y1; j++)//use nested loop that tests each coordinates
{
if(((2*pow(i,2)) + abs(2*i*j) + pow(j,2)) == 10000)//use if that checks condition as per the given question
{
cout<<"There is a planet at "<<i<<", "<<j<<endl;// print coordinates
count++;//incrementing count variable value
}
}
}
cout<<"Total number of planets detected are: "<<count<<endl;//print count value
return 0;
}
Explanation:
In this code, inside the main method long "x, x1, y, and y1" and integer "count, i, and j" type variable is declared that uses a long variable to input value from the user-end.
In the next step, two nested loops have defined that test each coordinate and define if block that checks condition as per the given question and use i, j, and count variable to print value with the message.

An aviation tracking system maintains flight records for equipment and personnel. The system is a critical command and control system that must maintain a global availability rate of 99%. The entire system is on a cloud platform that guarantees a failover to multiple zones within a region. In addition to the multi-zonal cloud failover, what other solution would provide the best option to restoring data and rebuilding systems if the primary cloud service becomes unavailable?
Answer:
offline backup solution
Explanation:
In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.
All of the following are true of functions except: Group of answer choices They define specific tasks that can be used at many points in a program A function call must specify the name and arguments of the function The definition of a function usually is visible to other functions The implementation of a function is hidden from the caller
Answer:
The definition of a function usually is visible to other functions.
Explanation:
In Computer programming, a function can be defined as a group of organized, reusable sets of code that is used to perform a specific task i.e a single but related action. Thus, a function accepts data as an input, process the data and return a single result or a set of results.
A parameter can be defined as a value that can be passed to a function. This value can be passed to a function either by reference or by value.
This ultimately implies that, parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
Hence, when you create classes or variables in a function, you can can set the values for their parameters.
Furthermore, the true statements about a function includes;
I. A function define specific tasks that reusable at many points in a program.
II. The name and arguments of the function must be specified by a function.
III. The implementation of a function is generally hidden from the caller.
