Answer:
Explanation:
The following code is written in Java it goes through the queue that was passed as an argument, loops through it and removes all the odd numbers, leaving only the even numbers in the queue. It does not add any more data structures and finally returns the modified queue when its done.
public static Queue<Integer> evens(Queue<Integer> queue) {
int size = queue.size();
for(int x = 1; x < size+1; x++) {
if ((queue.peek() % 2) == 0) {
queue.add(queue.peek());
queue.remove();
} else queue.remove();
}
return queue;
}
Binary values are used to denote the 'ON' and 'OFF' state of a computer. The 'ON' state is denoted by the binary value '1'
- The 'ON' state of a computer represents the mode when the computer system is running and can be used to perform computing operations.
- The binary values '0' and '1' are used to designate the ON and OFF state.
- When the computer is ON, it is designated by the binary value 1 ; while the OFF state is designated by the binary value 0.
Therefore, the number which signifies the ON state of a computer is 1.

- In the given case in the question, the network administrator finds that multiple unauthorized devices has gained access to the network.
- Option (A) is correct.
- Option (B) ARP Poisoning, (C) botnet and (D) Evil Twin attack are different and so are the wrong options.
Answer:
operating system
Explanation:
System software are those programs that many refer to as computer programs. The most basic function of system software is to manage the computer systems. It acts as an interface between the computer’s hardware and the end user. System software converts instructions that end users give to the computer into a machine understandable language. Examples of system software include operating systems, utility programs, device drivers, and windows systems. The operating system is responsible for the functioning of all the computer’s hardware parts. It is the software loaded into the system when the computer boots up. It manages everything, from the memory, to the CPU, and many other different tasks.
