Yes that is correct. True
In general, synchronous communication means you have to wait for the answer all the time. The programming logic is simpler, but the cost that you spend a lot of time waiting.
If the options are:
<span>a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.
a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)</span>
Answer:
The failsafe method when facial recognition method is unavailable is the Personal Identification Number (PIN) method.
Explanation:
The Personal Identification Number (PIN) option is available for setup for cases when other biometric authentication methods fail due to several reasons.
Answer:
// function with memory leak
void func_to_show_mem_leak() {
int *pointer;
pointer = malloc(10 * sizeof(int));
*(pointer+3) = 99;}
// driver code
int main()
{
// Call the function
// to get the memory leak
func_to_show_mem_leak();
return 0; }
Explanation:
Memory leakage occurs when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs by using wrong delete operator.
The delete operator should be used to free a single allocated memory space, whereas the delete [] operator should be used to free an array of data values.
