Explanation:

I don't know what language this is, but the functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.

The functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.

The first, print(val) will be printed, and here the value of val is 25 as set outside the function. Then the print(val) inside the example() will be printed, and here we have declared val as global and set its value to 15, And with last print as well, since the val is now global and with value 15, and hence the output will be 15. And hence the output is as above.

The execution of the program in the "for" loop  will be following

For k=0

=> val=1 and sum=0+1=1

For k=1

=> val=2 and sum=1+2=3

For k=2

=> val=3 and sum=3+3=6

For k=3

=> val=4 and sum=6+4=10

For k=4

=> val 5 and sum=10+5=15

For k=5

=> val=6 and sum=15+6=21

For k=6

=> val =7 and sum=21+7=28

For k=7

=> val=8 and sum=28+8=36

For k=8

val=9 and sum=36+9=45

So, all the iterations of for loop are completed and the output is 45.

Therefore, The functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.

Computer hardware is any physical device used in or with your machine, whereas software is a collection of programming code installed on your computer's hard drive. In other words, hardware is a product you can hold in your hand, whereas software cannot be held in your hand.

Hardware:

A computer or laptop typically consists of various hardware components, including:

1. Central Processing Unit (CPU): This is the main processing unit of a computer responsible for executing instructions and performing calculations.

2. Random Access Memory (RAM): It provides temporary storage for data and instructions that the CPU can access quickly.

3. Solid State Drive (SSD): These are storage devices for long-term data storage, including the operating system, software programs, and user files.

4. Motherboard: It connects and allows communication between various components of a computer, such as the CPU, RAM, and storage devices.

Software:

Software refers to the programs and applications that run on a computer system.

Some common types of software include:

1. Operating System (OS): It manages the computer's hardware and software resources, providing a user interface and enabling users to interact with the system.

2. Applications: These are software programs designed to perform specific tasks, such as word processing, web browsing, photo editing, or video playback.

The similarity between NTFS Share and Linux permissions is that they change the access permissions.

The difference is that NTFS permissions allow you to provide users with more granular access while share permissions are easier to manage and apply.

Share permissions do not apply to users who are logged in locally to the server, but NTFS permissions do. Share permissions, as opposed to NTFS permissions, let you limit the number of active connections to a shared folder. Share permissions are set up in the "Permissions" settings' "Advanced Sharing" properties.

The most restrictive permission will take precedence over the others if you employ NTFS permissions and sharing permissions simultaneously. The user will only be able to read the file or have a look at the things in the folder, for instance, if NTFS share permissions are set to Full Control but share permissions are set to "Read."

In conclusion, NTFS permissions allow you to provide users more granular access while share permissions are easier to manage and apply.
