Answer: Buffered
Explanation: Buffered memory is the memory contains registers between the modules of dynamic random access memory(DRAM).It is also known as registered memory. The purpose of using buffered memory to increase the stability and decrease the electrical load.
Other options are incorrect because ECC(error correcting code)memory is for correction and detection of incorrect data, non- parity memory is that don't utilize ECC module and multi-channel used for the increment in the rate of transmission between memory controller and DRAM.
Thus,the correct option is option buffered memory because of serial communication pattern with memory controller and parallel communication technique with chips .
Answer:
Explanation:
Following are the Semaphores:
Customers: Counts waiting customers;
Barbers: Number of idle barbers (0 or 1)
mutex: Used for mutual exclusion.
Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves
Shared data variable:
count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.
// shared data
semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;
int count_cust= 0;
void barber() {
while(true) { //shop is always open
wait(customers); //sleep when there are no waiting customers
wait(mutex); //mutex for accessing customers1
count_cust= count_cust-1; //customer left
signal(barbers);
signal(mutex);
cut_hair();
}
}
void customer() {
wait(mutex); //mutex for accessing count_cust
if (count_cust< n) {
count_cust= count_cust+1; //new customer
signal(customers); signal(mutex);
wait(barbers); //wait for available barbers get_haircut();
}
else { //do nothing (leave) when all chairs are used. signal(mutex);
}
}
cut_hair(){ waiting(cutting);
}
get_haircut(){
get hair cut for some time; signal(cutting);
}
Answer:
A. To set the primary contact on an account record when it is saved
Explanation:
After updating a Contact and then you set the Primary checkbox, the contact becomes the primary contact and this then updates the reference in the Parent Account. Triggers are used for this purpose and not workflow rule. In this case there is only one contact at a time that is set as Primary Contacts, and in the case where an Account does not have any Contacts, the first contact that is created is made the primary and the trigger sets that value in reference.
