Answer: A- 96.67%
Explanation: Juan's web server was down for an entire day last September.
The web server up time for the month of September is 1/30=0.0333 which is one day out of the 30 days in the month.
Therefore 1-0.0333= 0.96667 *100 = 96.67%
When working with arrays, most programming languages perform ________, which means they do not allow programs to use invalid subscripts. Group of answer choices
1. buffer overrun protection
2. None of these
3. bitwise data execution
4. array bounds checking subscript binding
Final answer:
In array operations, most programming languages use array bounds checking to prevent the use of invalid subscripts, ensuring memory safety.
Explanation:
When working with arrays, most programming languages perform array bounds checking, which means they do not allow programs to use invalid subscripts. The correct answer is option 4. Array bounds checking is a safety feature in many programming languages that prevents programs from accessing memory locations outside of the allocated array space.
This is important to prevent errors and potential vulnerabilities like buffer overruns, where an attacker could manipulate the program to execute arbitrary code by overwriting parts of the memory.
Suppose your cell phone carrier charges you a monthly fee of $30.00 for up to 300 minutes and $0.45 for each additional minute after the first 300. Assuming you used your phone for x minutes with x > 300, the total monthly fee would be?
If you used your phone for <= 300 minutes then the charge is $30.00 Assume the user enters a positive value for the number of minutes
30 + (x -300) * .45ç correct answer
Use the following template
A = 300 #CONSTANT fee for <= 300 minutes
m = int(input("Enter the number of minutes "))
c = 0 # initialize cost variable
if (m>300): # minutes>300
# calculations here to compute the solution above
# use the correct answer provided
print(" the cost for ", m, " minutes is ", c )
else: # here m is <= 300# s <= 0
print(" the cost for ", m, " minutes is ", A )
Answer:
# 30 + (x -300) * .45ç correct answer
A = 30 #CONSTANT fee for <= 300 minutes
m = int(input("Enter the number of minutes "))
c = 0 # initialize cost variable
if (m>300):
c = 30 + ((m - 300) * 0.45) #Cost when the minute is greater 300
print("The cost for ", m, " minutes is $",c )
else:
print("The cost for ", m, " minutes is $",A )
Explanation:
c = 30 + ((m - 300) * 0.45) #Cost when the minute is greater 300
First 300 is subracted from the given minute to get the extra minute, and then the extra minute is multiplied by $0.45 after which it is added to the constant of $30 for the 300 minutes
Consider the following code snippet: public class Motorcycle extends Vehicle { private String model; . . . public Motorcycle(int numberAxles, String modelName) { model = modelName; super(numberAxles); } } What does this code do?
Answer:
The answer is "The code will not be compiled".
Explanation:
Description of the given code as follows:
In the given code, the class "Motorcycle" is defined, which inherits the above class that is "Vehicle". Inside Motorcycle class a private string variable "model" is declared. In the next line, the parameterized constructor "Motorcycle" is defined, that accepts two different parameters, which is "integer and string", inside the constructor string variable model used to hold parameter "modelName" value, and use the super keyword to call above class variable "numberAxies", which is not defined in this code, that's why the code is not compiled.An engineer plans to connect three switches (SW1, SW2, and SW3) in a lab. Before connecting the switches, he starts by configuring all three switches as VTP servers, with matching CTP domain name and password. He then configures some VLANs on each switch so that switch SW3 has a revision number of 10, switch SW2 has a revision number of 6, and switch SW1 has a revision number of 8. Only then does he engineer connect the switches with trunks: first SW1 to SW2, then SW2 to SW3, and then SW3 to SW1. Switch SW1 is elected the STP root switch in VLAN 1. Which answer most accurately states which VLAN configuration database is used, and why?
Answer:
c. All use SW3's database because SW3 has the highest revision number.
Explanation:
In this particular configuration, the three switches will definitely be connected to one another by the presence of some path with the specific trunks. As a result, the database with the most revision number will ultimately win. The process of the STP election does not have any influence on the selection of the VTP.

The function's name (showSquare in this case)
The function's argument list (A single integer parameter in this case)
In the open and closing braces following we can define the function's before for example we may want the function to display the square of the integer parameter; then a complete program to accomplish this in C++ will go like this:
#include <iostream>
using namespace std;
void showSquare(int param);
int main()
{
showSquare(5);
return 0;
}
void showSquare(int param){
int square = param*param;
cout<<"The Square of the number is:"<<endl;
cout<<square;
}

Authorization is the process of granting rights to use an organization's IT assets, systems, applications, and data to a specific user. True or false?
Answer:
True
Explanation:
In computing context, authorization is a process that grant a specific user to use the computer resources that can include both hardware and software. In some cases, authorization is also granted to access private-owned data. Usually, the authorization is implemented by having a user to entry username and password in order to log into a system to use the resources.
There might also be different level of authorization. Each specific user has different privileged level to use the resources. For example, a staff from finance department can access the corporate financial information but the same info is not available to other department staffs
Answer:
True
Explanation:
Usually preceded by authentication (which means confirming the identity of a user), authorization is the process of granting access level rights to a user to use an organization's resources such as IT assets, systems, applications, and files.
By access level rights, we mean that depending on the level of authority of the user, they can access certain resources. For example, a mere user (or a regular staff) in an organization, might not have some administrative privileges such as editing files which might be given to other users who are admins. In other words, authorization also means controlling what users access what resources.

What can be controlled through IoT? Choose four answers.
Desktops
Door locks
Laptops
Light switches
Security cameras
Thermostat
Answer:
Door locks
Light switches
Security cameras
Thermostat
Explanation:
IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.
For Example
In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.
In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.
Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.

Explanation:
In Windows PC (e.g Windows 7), Last Known Good Configuration, is an option that helps users to start up their PC if it doesn't start normally. This option is only accessible at boot process by using the keyboard (mouse will not work at this point). So to access this option, the F8 key is pressed repeatedly or held down. This will display some start up menus where the user can use the arrow keys to access the option.
Assume that inputFile references a Scanner object that was used to open a file. Which of the following while loops is the correct way to read data from the file until the end of the file is reached?
Answer:
while(inputFile.hasNext()) { //some code here }
Explanation:
Even though you did not provide the options, here is how it should look like.
It is known in the question that there is an object called inputFile. To be able to read all the data from a file in Java, you need to use hasNext() function with the object. inputFile.hasNext() enables you to read the data in a file.
while(inputFile.hasNext()) { } enables you to loop through the file while it has something to read in a file.

Write a program that asks the user to enter ten temperatures and then finds the sum. The input temperatures should allow for decimal values. Sample Run Enter Temperature: 27.6 Enter Temperature: 29.5 Enter Temperature: 35 Enter Temperature: 45.5 Enter Temperature: 54 Enter Temperature: 64.4 Enter Temperature: 69 Enter Temperature: 68 Enter Temperature: 61.3 Enter Temperature: 50 Sum = 504.3
Answer:
#include <iostream>
#include <conio.h>
using namespace std;
main()
{
float temp[10], sum;
sum=0;
for (int i=1 ; i<= 10; i++)
{
cout<<"Enter the temperature in Decimal for temp"<<i<<"=";
cin>>temp[i];
}
for (int j=1 ; j<=10 ; j++)
{
sum = sum+temp[i];
}
cout<< "/nThe Total Temperature ="<<sum;
getch();
}
Explanation:
In this program we can take values of temperature in decimal values by taking the data type of temp variable as float. Array is used to enter the ten temperature values. Sum variable is used to add all the values.
The code example provided is a Python program that prompts the user to enter ten temperatures, validates the input as decimal values, accumulates the sum, and then prints out the total sum.
To write a program that asks the user to enter ten temperatures and then finds the sum, you would need a loop that runs ten times, prompting the user to input a temperature on each iteration. The program should allow for decimal values to be entered. Below is an example of how this can be implemented in Python:

Explain the distinction between interpretation and compilation. What are the comparative advantages and disadvantages of the two approaches?
12. Is Java compiled or interpreted (or both)? How do you know?
13. What is the difference between a compiler and a preprocessor?
14. What was the intermediate form employed by the original AT&T C++ compiler?
15. What is P-code? 16. What is bootstrapping? 17. What is a just-in-time compiler?
18. Name two languages in which a program can write new pieces of itself "on the fly."
19. Briefly describe three "unconventional" compilers—compilers whose purpose is not to prepare a high-level program for execution on a microprocessor.
20. List six kinds of tools that commonly support the work of a compiler within a larger programming environment.
21. Explain how an IDE differs from a collection of command-line tools.
Answer:
11: Compiler translates a high level source program into a target equivalent (machine language).
An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.
12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)
13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.
14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language
15: Stack-based language, similar to modern Java compiler byte code
16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.
17: A compiler which translates byte code into machine language immediately prior to each program execution.
18: Lisp and Prolog
19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.
21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.
