Answer:
The Compass
Explanation:
The compass was one of the foremost technological inventions that forever changed sea navigation.
Before its invention, sailors used landmarks to navigate and when it got dark, they had to stop and wait for daybreak before resuming their journey. Some other people used the inaccurate means of the sun and stars to navigate at sea.
But with the invention of the compass, all these problems were a thing of the past because the compass could provide direction despite the weather or time of the day and as a result, it opened more trade routes and assisted in the Age of Discovery.

Answer:
SELECT TECHNAME, EMPNUM, YEAR FROM EMPLOYEE ORDER BY YEAR DESC
Explanation:
The table definition is not given;
However, I'll make the following assumptions
Table Name:
Employee
Columns:
Technician name will be represented with Techname
Employee number will be represented with Empnum
Year Hired will be represented with Year
Having said that; the sql code is as follows:
SELECT TECHNAME, EMPNUM, YEAR FROM EMPLOYEE ORDER BY YEAR DESC
The newest year hired will be the largest of the years;
Take for instance:
An employee hired in 2020 is new compared to an employee hired in 2019

End
end
Answer:
Following are the description to the given code:
Explanation:
In the given code, three for loop are used that uses the variable "I, J, and K", which starts from 1 and ends when it equal to the value of the "n".
Inside the "I and J" loop, another variable "C" is defined, which uses "i,j" and assign a value, that is equal to 0. In the "k" loop, it uses the "c[i.j]" to multiply the value of "a[i.k] and b[k.j]".
In other words, we can say, it calculates the multiplication of the matrix and stores its calculated value.

Consider a variation of Sequential Search that scans a list to return the number of occurrences of a given search key in the list. Does its efficiency differ from the efficiency of classic Sequential Search? Explain.
Answer:
Considering the fact that the sequential search key must go through the entire list, The search is no different from a classic sequential search.
Explanation:
Sequential search is a form of search in computer science that searches for an item by comparing sequentially items in an ordered list. In big O notation, it take the sequential search O(n) time, with n being the number of items in the list.
This is the same as searching for the occurrence of an item multiple times in the list, as it must go through the entire list items.

The internal LAN is generally considered a trusted zone.
a. True
b. False
Answer:
Option A:
True
Explanation:
The internal LAN is generally considered a trusted zone because it is only accessible by a limited number of users each with a specific administrative privilege. Reduces the occurrence of threats to the system as most of the users are profiled, documented, and well known.
It is a lot more difficult to hack into an internal LAN because of its closed nature, with only a limited number of devices connected. Tracing the source of a security breach is also a lot easier compared to a Wide Area Network.

write a python function that takes the largest and smallest numbers in a list, and swap them (without using min() or max() )
Answer:
def SwapMinMax ( myList ):
myList.sort()
myList[0], myList[len(myList)-1] = myList[len(myList)-1], myList[0]
return myList
Explanation:
By sorting the list, you ensure the smallest element will be in the initial position in the list and the largest element will be in the final position of the list.
Using the len method on the list, we can get the length of the list, and we need to subtract 1 to get the maximum element index of the list. Then we simply swap index 0 and the maximum index of the list.
Finally, we return the new sorted list that has swapped the positions of the lowest and highest element values.

Set hasDigit to true if the 3-character passCode contains a digit.
#include
#include
#include
using namespace std;
int main() {
bool hasDigit;
string passCode;
hasDigit = false;
cin >> passCode;
/* Your solution goes here */
if (hasDigit) {
cout << "Has a digit." << endl;
}
else {
cout << "Has no digit." << endl;
}
return 0;
Answer:
Add this code the the /* Your solution goes here */ part of program:
for (int i=0; i<3; i++) { //iterates through the 3-character passCode
if (isdigit(passCode[i])) //uses isdigit() method to check if character is a digit
hasDigit = true; } //sets the value of hasDigit to true when the above if condition evaluates to true
Explanation:
Here is the complete program:
#include <iostream> //to use input output functions
using namespace std; // to identify objects like cin cout
int main() { // start of main function
bool hasDigit; // declares a bool type variable
string passCode; //declares a string type variable to store 3-character passcode
hasDigit = false; // sets the value of hasDigit as false initially
cin >> passCode; // reads the pass code from user
for (int i=0; i<3; i++) { //iterate through the 3 character pass code
if (isdigit(passCode[i])) // checks if any character of the 3-character passcode contains a digit
hasDigit = true; } //sets the value of hasDigit to true if the passcode contains a digit
if (hasDigit) { // if pass code has a digit
cout << "Has a digit." << endl;} //displays this message when passcode has a digit
else { //if pass code does not have a digit
cout << "Has no digit." << endl;} //displays this message when passcode does not have a digit
return 0;}
I will explain the program with an example. Lets say the user enters ab1 as passcode. Then the for loop works as follows:
At first iteration:
i = 0
i<3 is true because i=0
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[0] points to the first character of pass code i.e. a which is not a digit. So the value of i is incremented to 1
At second iteration:
i = 1
i<3 is true because i=1
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[1] points to the second character of pass code i.e. b which is not a digit. So the value of i is incremented to 1
At third iteration:
i = 2
i<3 is true because i=2
if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to true because passCode[3] points to the third character of pass code i.e. 1 which is a digit. So the hasDigit = true; statement executes which set hasDigit to true.
Next, the loop breaks at i=3 because value of i is incremented to 1 and the condition i<3 becomes false.
Now the statement if (hasDigit) executes which checks if hasDigit holds. So the value of hasDigit is true hence the output of the program is:
Has a digit.
