Imagine running a 64-bit system on a 32-bit system, where we simulate a single 64- bit memory location (register) using two atom

ic 32-bit memory locations (registers). A write operation is implemented by simply writing the first 32-bits of the simulated 64-bit register in the first real register, then the second 32-bits in the second real register. A read, similarly, reads the first half from the first register, then the second half from the second register, and returns the concatenation. What is the strongest property that this 64-bit register satisfies: safe, regular, or atomic

Answer:

It's not possible to ensure memory access occurs indivisibly when it has to broken into multiple operations. Unfortunately, the fact that your application is running on a 64-bit kernel does not change the equation any - it is actually running in a compatibility layer and has none of the benefits of x64

Discuss advantages and disadvantages of operating system
Serjik [45]

Answer and Explanation:

Advantages-

  1. Computing source- Through the operating system, users can communicate with computers to perform various functions such as arithmetic calculations and other significant tasks.
  2. Safeguard Of Data- There’s a lot of user data stored on the computer. Windows Defender in Microsoft Windows detects malicious and harmful files and removes them. Also, it secures your data by storing them with a bit to bit encryption.
  3. Resource Sharing- Operating systems allow the sharing of data and useful information with other users via Printers, Modems, Players, and Fax Machines. Besides, a single user can share the same data with multiple users at the corresponding time via mails. Also, various apps, images, and media files can be transferred from PC to other devices with the help of an operating system.

Disadvantages-

  1. Expensive- It is costly.
  2. System Failure- System failures may occur. If the central operating system fails, it will affect the whole system, and the computer will not work. If the central system crashes, the whole communication will be halted, and there will be no further processing of data.
  3. Virus Threats- Threats to the operating systems are higher as they are open to such virus attacks. Many users download malicious software packages on their system which halts the functioning of OS and slow it down.

int main()

{

FILE * file_object;

char file_name[100];

char ch;

int characters=0, words=0;

printf("Enter source file name: ");

scanf("%s", file_name); //asking user to enter the file name

file_object = fopen(file_name, "r"); //open file in read mode

if (file_object == NULL)

{

printf("\nUnable to open file.file not exist\n"); //check if the file is present or not

}

while ((ch = fgetc(file_object)) != EOF) //read each character till the end of the file

{

if (ch == ' ' || ch == '\t' || ch == '\n' || ch == '\0') //if character is space or tab or new line or null character increment word count

words++;

else

characters++; //else increment character count this assures that there is no spaces count

}

printf("The file story.txt has the following Statistics:\n"); //finally print the final statistics

if (characters > 0)

{

printf("Words: %d\n", words+1); //for last word purpose just increment the count of words

printf("Characters (no spaces): %d\n", characters);

}

fclose(file_object); //close the file object

return 0;

}

Urgent will give brainliest who solves this....
Ratling [72]
THIS IS MY PERSONAL OPINION:
The world is indeed changing very fast, and the future brings new possibilities and new realities. I foresee that humans will thrive for another 50 years, until the global warming situation reaches its limits. The people in the future I think will not have any ( maybe rarely) social interactions, maybe we will go to the moon etc. but i still strongly believe that the end of humanity is decades close.
I hope this helps you :)
