Answer:
The given statement is False
Explanation:
OSI or Open System Interconnection is a reference model around which the networks are built. OSI gives us all the information regarding movement of data from a software through physical means to another software. Generally it is used as a guidance tool. Seven layers combine to build an OSI model/
TCP/IP (Transmission control protocol/ Internet protocol) model is in a way implementation of the OSI model. It tells about the end-to-end transmission of data being transmitted using OSI model.

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:
The largest safety threat to the ISS are the micrometeorite and orbital debris (MMOD) fires, impacts and toxic spills. These pose the biggest threat to the ISS astronauts.
Explanation:
The debris is as a result of collisions. An observation revealed that once a certain mass is passed, collisions give rise to more debris.
Another report revealed that the station has about 55% chance of being hit by tiny space rocks over a 10-year period. They can protected by installing new impact-protecting panels to the exterior of the station.
ISS means International Satellite Station.
