Answer:
A mouse.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, scanner, projector, mouse, etc.
A mouse is an input device that is designed and used to select specific menu options, drag and drop options and to draw something on screen.
You make a purchase at a local hardware store, but what you've bought is too big to take home in your car. For a small fee, you arrange to have the hardware store deliver your purchase for you. You pay for your purchase, plus the sales taxes, plus the fee. The taxes are 7.5% and the fee is $20. (i) Write a function t(x) for the total, after taxes, on the purchase amount x. Write another function f(x) for the total, including the delivery fee, on the purchase amount x. (ii) Calculate and interpret (f o t)(x) and (t o f )(x). Which results in a lower cost to you
Answer:
[tex]f(x) = 1.075x[/tex]
[tex]t(x) = x + 20[/tex]
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = 1.075x + 20[/tex]
Explanation:
Given
[tex]Tax = 7.5\%[/tex]
[tex]Fee = \$20[/tex] -- delivery
Solving (a): The function for total cost, after tax.
This is calculated as:
[tex]f(x) = Tax *(1 + x)[/tex]
Where:
[tex]x \to[/tex] total purchase
So, we have:
[tex]f(x) = x * (1 + 7.5\%)[/tex]
[tex]f(x) = x * (1 + 0.075)[/tex]
[tex]f(x) = x * 1.075[/tex]
[tex]f(x) = 1.075x[/tex]
Solving (b): Include the delivery fee
[tex]t(x) = x + Fee[/tex]
[tex]t(x) = x + 20[/tex]
Solving (c): (f o t)(x) and (t o f)(x)
[tex](f\ o\ t)(x) = f(t(x))[/tex]
We have:
[tex]f(x) = 1.075x[/tex]
So:
[tex]f(t(x)) = 1.075t(x)[/tex]
This gives:
[tex]f(t(x)) = 1.075*(x + 20)[/tex]
Expand
[tex]f(t(x)) = 1.075x + 21.5[/tex]
So:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = t(f(x))[/tex]
We have:
[tex]t(x) = x + 20[/tex]
So:
[tex]t(f(x)) = f(x) + 20[/tex]
This gives:
[tex]t(f(x)) = 1.075x + 20[/tex]
We have:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex] ---- This represents the function to pay tax on the item and on the delivery
[tex](t\ o\ f)(x) = 1.075x + 20[/tex] --- This represents the function to pay tax on the item only
The x coefficients in both equations are equal.
So, we compare the constants
[tex]20 < 21.5[/tex] means that (t o f)(x) has a lower cost

The router is physically located in a server room that requires an ID card for access. You backed up the router configuration to a remote location in an encrypted file. You access the router configuration interface from your notebook computer using a Telnet client with the username admin and the password admin. You used the MD5 hashing algorithm to protect the password. What should you do to increase the security of this device
Answer: Use an SSH client to access the router configuration.
Change the default administrative username and password
Explanation:
Based on the information given, in order to increase the security of the device, it's vital to use an SSH client to access the router configuration. The SSH client refers to the program that helps in establishing an authenticated and secure SSH connections to the SSH servers. It's vital for operating network services securely over a network that's unsecured.
Also, the default administrative username and password should be changed to a more secure username and password which can't be easily known by a third party.

Given n, take the sum of the digits of n. If that value has more than one digit, continue reducing in this way until a single-digit number is produced. The input will be a non-negative integer.
Answer:
int digitSum(int n) {
int sum = 0;
while (n) {
sum += n % 10;
n /= 10;
}
return sum < 10 ? sum : digitSum(sum);
}
int main()
{
int n = 12345;
printf("Digit sum of %d is %d\n", n, digitSum(n));
}
Explanation:
The recursion takes care of the repeated summing in case the sum has more than 1 digit.

Answer:
provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified
Explanation:
I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.

Which SCSI standard allows for the technique known as “hot swapping”? Ultra SCSI Original SCSI Serial SCSI Fast-Wide SCSI
Answer:
Serial SCSI
Explanation:
Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.
Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.

When a statement within a try block causes an exception, the remaining statements in the try block Select one: a. are executed after the statements in the catch block b. are executed before the statements in the catch block c. aren't executed
In C++, 'Try block' comprises of a group of statements in which there is a probability of an exception to take place.
C). The statements that would be left in the try block in case a particular statement leads to an exception 'can't be executed.'
In case an exception takes place, the left statements in the try block fail to function. This is the primary reason for which a catch block immediately succeeds a try block in order to deal with the exception and help close that code to allow the statements to work. Thus, option C is the correct answer.Learn more about 'Try block' here:
