Answer:

True                

Explanation:

  • CMOS (complementary metal-oxide-semiconductor) is a chip which is placed on the motherboard in order to store the system date and time and this is powered by a CMOS battery which is housed inside this chip and is used to manage the date and time when the system is off.
  • This is a long lasting battery which can work till the life of a motherboard.
  • This battery is also used to maintain BIOS settings and hardware settings and BIOS uses it during the booting process in order to retrieve the stored information regarding the hardware or system date time.
  • CMOS chip is basically volatile and cannot retain settings information when the computer system powers off but the CMOS battery helps to maintain these setting just like system time and date when the computer gets shut down.

Answer:

10

-1

Process finished with exit code 0

Explanation: see code bellow

public class BinarySearchRecursive {

   public static int binarySearch(int[] a, int key) {

       return binarySearchRecursiveHelper(a, key, 0, a.length - 1);

   }

   public static int binarySearchRecursiveHelper(int[] arr, int target, int start, int end) {

       if (start > end) {

           return -1;

       }

       int mid = (start + end) / 2;

       if (arr[mid] == target) {

           return mid;

       } else if (target < arr[mid]) {

           return binarySearchRecursiveHelper(arr, target, start, mid - 1);

       } else {

           return binarySearchRecursiveHelper(arr, target, mid + 1, end);

       }

   }

   public static void main(String[] args) {

       int[] a = {-4, 2, 7, 10, 15, 20, 22, 25, 30, 36, 42, 50, 56, 68, 85, 92, 103};

       int index = binarySearch(a, 42);   // 10

       System.out.println(index);

       index = binarySearch(a, 66);   // -1

       System.out.println(index);

   }

What two statements about IPv6 addresses are true? This task contains the radio buttons and checkboxes for options. The shortcut
Oliga [24]

Answer:

A and C

Explanation:

Option A:

In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”  

Here is an example

How to reduce the following IPv6 address?

ff02:0000:0000:0000:0000:0000:0000:d500

Ans: ff02::d500

Example 2:

2001:ed02:0000:0000:cf14:0000:0000:de95

Incorrect Answer -> 2001:ed02::cf14::de95  

Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:

Correct Answer -> 2001:ed02::cf14:0:0:de95

Or

2001:ed02:0:0:cf14::de95

Option C:

Since in IPv6 there are 2^{128} available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.
