With more and more users using mobile to look at websites, it is key that you optimise your site so users can find it when searching online. Which two elements should you look to optimise for improved SEO performance?
Answer:
Site speed and usability.
Explanation:
Web pages are developed using web development tools like HTML, CSS, JavaScript etc. A collection of these web pages are called a website. The web is a hosted for internet use in a web server.
All requests for a website in a web server is done in a web browser in a client device. For a website to be easy searched for , the search engine optimisation technique is used.
A hosted website on a server must have a unique and usable domain name and the page loading on a browser should be made faster by optimising the size of the scripting language.

If our list called List is populated as [0, 1, 2, 3, 4], what happens if our code tries to access List [5] per the rules of the AP Computer Science Principles Reference Guide?
Answer:
The number 4 will be returned.
Explanation:
Given;
List = [0, 1, 2, 3, 4]
Using the AP Reference Guide;
The first element has an index of 1 and can be accessed using the same. i.e
=> List[1] = 0
The second element has an index of 2 and can be accessed using the same. i.e
=> List[2] = 1
Therefore, if our code tries to access List[5], then the number at index 5 will be returned. i.e
=> List[5] = 4
This implies that the last number 4 will be returned.
Note: Many programming languages (such as Java) actually start their collection (array, list) index from 0 rather than 1. But since we are using the AP Computer Science Principles Reference Guide, the index has to start from 1.
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
The biggest change affecting computer security that has occurred over the last 30 years has been the transformation of the computing environment from a highly interconnected network of smaller systems to large mainframes.
Answer:
False
Explanation:
The change that occurred to computing over the last 30 years was the shift from large mainframes to the highly interconnected networks of smaller systems. Users in time past need to be in a fixed location to be able to use the computer, but over the years size of computers were reduced significantly to very portable devices sharing resources over the internet and can have access to a work server fro any location.
An intranet is a network based on Web technologies that allows selected outsiders, such as business partners and customers, to access authorized resources of a company’s extranet.
(A) True
(B) False
Answer:
(A) True
Explanation:
Intranet is a network accessible only for the authorized users. For example, an organization intranet is accessible only for the organization members and same authorized non-members (business partners)
Intranet has a restricted network via special network protocols.
The statement is (B) False. An intranet is a private network that is not accessible by outsiders, while an extranet allows limited access to selected outsiders.
Explanation:The statement is (B) False.
An intranet is a private network that uses Internet technologies to provide access to authorized users within a specific organization. It is not accessible by outsiders such as business partners and customers.
Extranet is a separate network that allows selected outsiders to access certain resources of a company. It can be considered an extension of the company's intranet, but with limited access given to external parties.

The design strategy that starts with a global view of the entire problem and breaks the problem down into smaller, more manageable subproblems is known as what type of design?
Answer:
Top down design
Explanation:
Top-down design is an approach that is used to break down the problem into the smaller subpart so that it can be manageable into more clear form.
C programming is the example of a top-down approach while C++ is the example of the bottom-up approach.
The advantages of the top-down design approach are:
1) easy to manage
2) easy to find the error
3) easy to debug

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.

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.
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.
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.
What computer is designed to meet the computing needs of several people simultaneously in a small to medium-size business environment?

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:
sum_temperatures = 0Refer to the exhibit. The switch does the routing for the hosts that connect to VLAN 5. If the PC accesses a web server from the Internet, at what point will a VLAN number be added to the frame?
Answer:
no VLAN number is added to the frame in this design.
Explanation:
As can be seen in the exhibit shown in the picture below it can be said that the in this scenario no VLAN number is added to the frame in this design. Usually in many scenarios the switch or router is in charge of applying a VLAN number, which is a number between 0 and 4095, to every port that has a connection to the switch or router.

The IMA standard that includes disclosing all relevant information that could reasonably be expected to influence an intended user’s understanding of the reports, analyses, or recommendations is ________.
Answer:
Credibility.
Explanation:
The IMA or institute of management and accounting is one of the largest and most respected group or association of accountants and other financial professionals in the business industry, with the collaborative intent to advance and promote the management and accounting profession.
All members of the association obligatorily adhere to four principles. They are, honesty, fairness, objectivity and responsibility. And they also follow four IMA standards, which are credibility, competence, integrity and confidentiality.
The credibility standard includes disclosing all relevant information that could reasonably be expected to influence an intended user's understanding of the reports, analyses or recommendation.
The IMA standard requiring disclosure of all relevant information for understanding reports, analyses, or recommendations is grounded in the principle of transparency. This encompasses the clear presentation of data and an easily understandable format, adhering to the ISO 9000 Management Categories for quality and continuous improvement.
Explanation:The IMA standard that includes disclosing all relevant information that could reasonably be expected to influence an intended user’s understanding of the reports, analyses, or recommendations is transparency. Ensuring transparency involves the presentation of monitoring results and data in such a manner that stakeholders can fully comprehend the scope, methodology, biases, and limitations of the research. It is important to consider not only the content but also the format to make sure that the information is accessible and easily understandable.
According to the ISO 9000 Management Categories, part of this transparency involves clear communication and documentation that reveal what the organization planned to do, what it actually did, and the continuous improvement practices that are in place. This principle of transparency is vital to ensure that data, conclusions, and recommendations are fully understood by all stakeholders.
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.
