Answer:
The technologies that Ann will MOST likely use to connect the pedometer to her desktop to transfer her information to the website are:
a. Bluetooth
and
c. NFC
Explanation:
Bluetooth and NFC (Near Field Communication) are wireless technologies that enable the exchange of data between different devices. Bluetooth operates on wavelength. NFC operates on high frequency. The security of NFC over Bluetooth makes it a better tool of choice. NFC also operates on a shorter range than Bluetooth, enabling a more stable connection. NFC also enjoys a shorter set-up time than Bluetooth. It also functions better than Bluetooth in crowded areas. Tethering requires the use of physical connectors. Infrared is not a connecting technology but wave radiation.

data management (10 marks)
Explain how data structure and uses of computer in data management
Answer:
Data management is a important tool for data handling.
Explanation:
A good knowledge about the data stricture and data management is a prerequisite for working with codes and algorithms. It helps to identify the techniques for designing the algorithms and data storage in the system. It helps to find out the data hierarchy. Thereby allowing the data management in an efficient and effective way. It can increase the skills in computer programmingIn a file called amortizedAnalysis.pdf, please provide answers to the following questions: How many cost units are spent in the entire process of performing 40 consecutive append operations on an empty array which starts out at capacity 5, assuming that the array will double in capacity each time a new item is added to an already full dynamic array

is a security design principle to direct the selection of control layers for an organization's computing enclave to ensure its resilience against various methods of attack. This also reduces the likelihood of a single point of failure in the security of the overall system.
Answer:
Defense in Depth (DiD).
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Defense in Depth (DiD) can be defined as a concept or framework in cyber security that typically involves the process of layering multiple defensive mechanisms and security control throughout an information technology (IT) system, so as to prevent data theft or an unauthorized access to user data.
Basically, this cyber security technique is designed such that when a layer of the defensive mechanism fails, another security layer step in to mitigate and prevent the attack. Thus, it causes redundancy when an attacker exploits a vulnerability in a system, a breach of security or when one of the security layers fail.

If a tweet is posted 10 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.)
Answer:
1.8 * 10^11 m
Explanation:
Given that :
Time taken for tweet to me posted after been sent, t = 10 minutes
t in seconds :
60 seconds = 1 minute
10 minutes = (10 * 60) = 600 seconds
Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s
Recall :
Speed = distance / time
Distance = speed * time
Distance of Curiosity from Earth = (3 * 10^8 * 600)
Distance of curiosity from earth = 1.8 * 10^11 m

Write a program named lastname_firstname_cities.py that works with information about large cities. Your program will open the cities.txt downloadfile. Each line in the file has the name of a city, its country, and its population. The first few lines of the file look like this:
Answer and Explanation:
Open your text editor and open new file. Save new file file as lastname_firstname_cities.py. The program will open the file cities.txt downloadfile hence :
dfile= open(cities.txt, "r")
If we write this into our lastname_firstname_cities.py file it will open our cities.txt downloadfile in read mode and text mode(by default unless we specify binary mode which is for images)
cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:
Answer:
#include <iostream>
int main() {
// The length of the list
int l;
// The array containing the numbers
int *list;
// Threshold, last value in array
int thresh;
// Read in first value and create an array with the size of that value
scanf("%d", &l);
list = (int*) malloc(l * sizeof(int));
for(int i = 0; i < l; i++) {
scanf("%d", &list[i]);
}
thresh = list[l - 1];
// Print the values
for(int i = 0; i < l - 1; i++) {
if (list[i] <= thresh) {
printf("%d ", list[i]);
}
}
printf("\n");
free(list);
}
Explanation:
The program assumes at least two values are provided. The length of the list and the threshold.
We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.
g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

Explanation:
Write a C++ function using recursion that returns the Greatest Common Divisor of two integers. The greatest common divisor (gcd) of two integers, which are not zero, is the largest positive integer that divides each of the integers. For example, the god of 8 and 12 is 4.
Answer:
The function is as follows:
int gcd(int num1, int num2){
if (num2 != 0){
return gcd(num2, num1 % num2);}
else {
return num1;}
}
Explanation:
This defines the function
int gcd(int num1, int num2){
This is repeated while num2 is not 2
if (num2 != 0){
This calls the function recursively
return gcd(num2, num1 % num2);}
When num2 is 0
else {
This returns the num1 as the gcd
return num1;}
}

Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);
Answer:
The true statements are :
A. assertEquals(student1,student2)
C. assertSame(student1,student3)
Explanation:
AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.
Methods are collections of named code segments that are executed when evoked
The assertion method that will return true for the given code is: assertEquals(student1,student2)
The code segment is given as:
Student student1 = new Student();
Student student2 = new Student();
Student student3 = student1;
In Java, the assertEquals() method returns true if two objects have equal values.
Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true
