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.

How do the World Wide Web and the Internet work together?
Firlakuza [10]

Answer:

Explanation:

The relationship between the World Wide Web and the Internet is that the Internet is a collection of connected computers through gateways by which the information that is stored in databases and on servers is transferred from one computer to another and the World Wide Web is the software that is used to retrieve the information requested by the users.  The World Wide Web (which we call the Web because we’re lazy typists) lives “on top of” the Internet. The Internet’s network is at the core of the Web, and the Web is like an attractive parasite that requires the Net for survival (dummies.com, 2010).  The Web page that are accessible on the web usually contain hypertext links and are sometimes called links. These links connect to other pages that are store on the same or even a different server; these servers can be in any location throughout the World.  This system of interlinked documents is known as hypertext (Dummies.com, 2010).

Links can create connections that let you go directly to related information. These invisible connections between pages are like the threads of a spider web — as you click from Web page to Web page, you can envision the Web created by the links. What’s so remarkable about the Web is that it connects pieces of information from all around the planet, on different computers and in different databases (Dummies.com, 2010).  Every Web page has a name attached to it so that browsers, and you, can find it. The name of this naming convention: URL, or Uniform Resource Locator. Every Web page has a URL, a series of characters that begins with http://. (Pronounce each letter, “U-R-L” — no one says “earl.”), (Dummies.com, 2010).  The Internet is a world wide network of computers that are connected (networked) and are using the communication method called TCP/IP. The Internet was named ARPANET in 1969 by the Advanced Research Projects Agency of the U.S. Department of Defence with just four computers connected together (Comentum.com, 2010).  The Internet, sometimes called simply “the Net,” is a worldwide system of computer networks – a network of networks in which users at any one computer can, if they have permission, get information from any other computer (SearchWinDevelopment.com, 2010).  Computers are connected to the Internet via modems and gateways. Some computers are used as servers which are continuously connected to the Internet and used to store web pages; these computers are usually referred to as servers. A house hold computer is primarily used by ordinary people to search for information on the web is usually known as a client. The request for information or search result is passed by the browser on the client to the server that contains the pages which have the relevant information in them via the net. The request passes through the modem then along the net to the correct server, the server then serves up the correct page, which is then sent back to client computer and presented to the user through the browser.
