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.

Answers

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:

I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?

a. hard drive is full

b. photos were taken in a different country

c. USB port is broken

d. the file structure of the 2 hard drives are not compatible

Answers

Your answer is D.

Hope this helps and if you could answer the question I just uploaded titled giving brainliest that would be great. Basically, what you have to do is research why the book titled the list of things that will not change and explain why it’s your favorite book based on the message it tells you! Go to my profile and go to questions.

The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.

The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.

Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:

JPEGPNGJFIF

Any external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.

The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false

Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:

"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"

The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

Select the correct statement(s) regarding IP addressing.
a. IPv4 and IPv6 addressing is fully compatible with one another.
b. CIDR address format represents a Class C network only used within an intranet.
c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.

Answers

Yeah the answer is b

Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

What is an IP address?

A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.

Only C is correct, rest other statements are incorrect because:

a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.

b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.

Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.
