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.
Answer:
True.
Explanation:
Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers have several CPUs, have very fast processor speeds, can supporting multiple operating systems and have huge amounts of storage capacity. As a result, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.
Answer:
The correct answer to the following question will be Option A (Bank).
Explanation:
- Sometimes on a motherboard, the memory modules are grouped into different groups and that each group is named as a branch. Furthermore, the term "bank" may be used loosely to describe a basic computing data storage area. When the record is stored in the database it can be accessed at a specific time by the user.
- Because the 486 is a 32-bit processor and a 30-pin SIMM is 8-bit, four SIMMs (8x4=32) is called a bank when installing memory on an 80486 processor computer; Install four 16 MB SIMMs when upgrading to 64 MB.
Therefore, Option A is the right answer.
