Answer:
Jenny should order a SO-DIMM RAM module.
Explanation:
SO-DIMM stands for (Small Outline Dual In-line Memory) and is the laptop version of the RAM used on desktop computers. These modules are smaller than the ones used on a desktop PC and therefore have less pins than the PC versions (204 vs 240).
Usually the amount of RAM found on a laptop is smaller than the one found on a desktop PC because of the size of the motherboards. Generally on a normal computer you can add up to 4 RAM modules instead of the 2 modules that are generally found on a laptop PC.

Answer:
You go to the launcher, then find Photo Booth. Photo Booth allows you to take photos. You can only take photos on the side where the screen is, since there isn't a camera on the back. I recommend taking a picture with a phone instead. For a screenshot, press command-shift-3.
Hope this helps!
Answer:
A mutex is used here.
A mutex is a locking mechanism set before using a shared resource and is released after using the shared resource. When the lock is set, only one task accesses the mutex.
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<pthread.h>
#include<unistd.h>
pthread_t tid[2];
int flag=0;
int a = 0;
pthread_mutex_t lock = PTHREAD_MUTEX_INITIALIZER;
void *thread_a(void *arg)
{
pthread_mutex_lock(&lock);
a += 2;
pthread_mutex_unlock(&lock);
flag = 1;
return NULL;
}
void *thread_b(void *arg)
{
int b = 0;
if(flag){
b++;
}
b += 3;
pthread_mutex_lock(&lock);
a -= b;
pthread_mutex_unlock(&lock);
return NULL;
}
int main()
{
while(1) {
pthread_create(&tid[0],NULL,thread_a,NULL);
pthread_create(&tid[1],NULL,thread_b,NULL);
sleep(1);
}
pthread_exit(NULL);
return 0;
}
