When you save something to the Desktop on a school computer, the drive letter it will save to the C drive.

<h3>What is a C drive?</h3>

C drive is that part of the computer that contains the operating system and files of the system. The files on which we worked are saved on the C drive of the system.

This is a type of hard drive. The work we have done on the system is automatically saved on the drive. We can easily find the C drive on the computer's file explorer. It automatically saved the data, but you can save manually the data of the D drive.

Thus, the drive letter it will save to the C drive.

Using the program below, explain what the output will be at LINE A. 1 #include 2#include 3#include 4 5 int value - 128; 6 7 int

slega [8]

Answer:

This is the complete correct program:

#include <stdio.h>

#include<sys/types.h>

#include<unistd.h>

int value = 128;

int main()

{

pid_t pid;

pid=fork();

if (pid==0) /* child process */

{

value +=8;

return 0; }

else if (pid > 0) {/* parent process */

wait (NULL);

printf ("PARENT: value =%d\n" ,value); /* LINEA */

return 0;

}

The output of the LINE A is:

PARENT: value = 128

Explanation:

The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.

In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement

value +=8;

Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :

else if (pid > 0)

{ wait (NULL);

printf ("PARENT: value =%d\n" ,value);

return 0; }

So the value 128 is printed at the end in the output.

wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.

So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.

1. Explain the distinction between interpretation and compilation. What are the comparative advantages and disadvantages of the

serious [3.7K]

Answer:

11: Compiler translates a high level source program into a target equivalent (machine language).

An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.

12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)

13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.

14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language

15: Stack-based language, similar to modern Java compiler byte code

16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.

17: A compiler which translates byte code into machine language immediately prior to each program execution.

18: Lisp and Prolog

19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.

21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.

What are the limits of hashing and verifying that files haven’t changed?

earnstyle [38]

The hashing function can take any number of key-value pairs and there is no specific limit to it.

<h3>What is hashing?</h3>

Hashing is a file-based algorithm for producing a fixed-length bit string value. A file is essentially a collection of data blocks. The length of the data is reduced by hashing to a fixed number or key that represents the original string.

When hashing is employed, the hash function may plot all of the keys and values to what the real size of the table is, demonstrating that the hashing function can take any number of key-value pairs with no restriction.

However, if the passwords are hashed in encryption, recovering the passwords is extremely difficult.

Thus, the hashing function can take any number of key-value pairs and there is no specific limit to it.

Answer:

Salting is the preservation of food with dry edible salt. It is related to pickling in general and more specifically to brining also known as fermenting (preparing food with brine, that is, salty water) and is one form of curing.
