Which layer in the tcp/ip model is used for formatting, compressing, and encrypting data?
In the TCP/IP model, the application layer is used for compressing, formatting, encryption data.
The TCP/IP is a four layered model in which each layer deals with different functionalities. Complex operations like data compressing, formatting and encryption are performed on the application layer in the TCP/IP model.
Data compressing: Data compression service is offered by the application layer in which the size of data frames is reduced so that they can quickly be exchanged over the network. Data formatting: Data formatting is another functionality of the application layer in which the application layer changes data from one format to another format according to defined specification for the purpose of further processing. Data encryption: The application layer also performs data encryption. In data encryption, the application layer converts the data from a readable plaintext to unreadable coded text.Besides data encryption, compressing and formatting, the application layer in TCP/IP model also offers many other services. These services include providing interface between two remote devices; communicating the entire data message; handling file transfer and web browsing; managing network connections; checking data authentication and authorization; and performing data synchronization.

The void pointerParameters(int &p, double q){...}In the function pointerParameters, the parameter p is a(n) reference parameter.
A reference parameter is a pointer to a variable's memory location. In contrast to value parameters, when you pass parameters by reference, a new storage location is not made for these parameters. The actual parameters that are passed to the method's reference parameters represent the same memory address.
The second technique to give arguments to a function is by call-by-reference. This technique copies the argument's address into the parameter but not its values. This address is used to obtain the actual argument mentioned in the call within the function.
When you need to alter the value of a call's actual parameter variable, use a reference parameter. It is seen to be better programming practise to return the value with the return statement when a function only computes one value.

Which term refers to a unique combination of a user name and an associated password?
User account is the term that refers to the unique combination of username and associated password. That is one of the best techniques to authenticate the user in order to give access to the system and use resources.
A username always paired with a password is stored in a database. They both together make a unique combination that is referred to as a user account. The user account uniquely identifies each user and grants the user access to the system.
For example, a computer system is set up with multiple users' accounts, with different usernames and passwords for each account. The respective user can only access the computer system through their particular user account, which is the unique combination of the username and the password.
Similarly, e-mail services also require users to make a user account with a combination of unique username and associated password in order to use email services. So, whenever users want to access their respective email user account, it is required to enter username and password. Access is granted only when both the username and password is entered correctly.
It may be possible that username appears on the screen but password is always kept secret by the systems/applications. By keeping the password private, a secure user account is created because only the authorized access is granted.

Create a program that allows the user to insert 30 integer numbers. The program should return the average of the positive numbers inserted that are multiples of 3 (the average should be a floating point number). If during the insertion the user enters a number x that is a divisor of 70 the total count of integers inserted should be decreased by x units.
E.g. the user may enter 31, 6, 10, 7, 19, 96, 5, 12 and then it should stop asking for numbers, because the total number of integers inserted is 8, but since 10, 7 and 5 were inserted, which are all divisors of 70, no more integers had to be asked for, since 8 + 10 + 7 + 5 = 30.
The program should return 38, since that is the average of 6, 96 and 12
In c++
A program that allows the user to insert 30 integer numbers. The program should return the average of the positive numbers inserted that are multiples of 3 is given below:

What is the advantage of the javascript facility localstorage object compared to cookies?
There are many advantages that the localstorage object has over cookies. First, localstorage is more secure since it is not sent back and forth between the server and the client like cookies are. This means that potential hackers cannot intercept and read localstorage data like they can with cookies.
Another advantage of localstorage is that it can store more data than cookies. While cookies are limited to 4KB, localstorage can store up to 5MB. This makes localstorage much more versatile and suitable for storing larger amounts of data.
Lastly, localstorage data is persistent, meaning it remains stored even after the browser is closed. In contrast, cookies are only stored temporarily and are deleted when the browser is closed. This makes localstorage ideal for storing data that needs to be accessed again later.

The bakery has requested the following custom variables:
-customer’s first name
-customer’s last name
-a coupon percentage off
-the date that they became a newsletter subscriber
Create an appropriate variable for each of these four items.
Then create string for the custom newsletter text that will show up before, between, and after each custom variable.
For example, “Hello,” might be the first string, followed by the variable carrying the customer’s name, followed by “Thanks for subscribing to our newsletter!” Your custom newsletter text should greet the person, then offer them a coupon, and then thank them for being a loyal customer.
Add placeholder names and information to populate into the variables for testing purposes by making up data for each. You can use your own name, for example, as this is simply a prototype or proof of concept. To do this, remember that the equals sign = between a variable and its value assigns that value to the variable.
Finally, use the print function to display the final newsletter text that includes all the required variables. This will display a final string that reads like a plaintext newsletter with the variables appropriately replaced by the defaults for each that you set in Step 1.
We can also combine two strings together in a single print function by using the + sign like this:
print(greetingTxt + firstName + bodyTxt1)
Code:
firstName = "Bill"
lastName = "Nye"
coupon = 15
joinDate = "January 14, 1973"
print("Hello, " + firstName + lastName)
print("Thanks for subscribing to our newsletter!")
print("Here's a coupon for " + str(coupon) + "% off for being subscribed since " + joinDate)

Wants to test a program he suspects may contain malware. what technology can he use to isolate the program while it runs?
If he wants to test a program he suspects may contain malware, then the technology he can use to isolate the program while it runs is, B.Sandboxing.
Sandboxing can be described as a type of technology that uses the phenomenon of isolation to segregate a suspected file or program and then observes that distrustful program. If the program exhibits threatful activity under observation then it is removed so that the system can be protected by inhibiting its spread. Hence, the correct option is Sandboxing
On the other hand, Address Space Layout Randomization (ASLR) does not involve isolation as it just functions by arbitrarily organizing the address space locations to protect the memory contents. Hence, ALR Address Space Layout Randomization is not the correct option.
Process isolation usually is not involved in protection purposes as it just prevents the overlapping of different processes so that they do not intermix with each other. Hence, Process isolation is not the correct option.
