Consider the following method, which implements a recursive binary search. /** Returns an index in nums where target appears if target
* appears in nums between nums[lo] and nums[hi], inclusive;
* otherwise, returns -1.
* Precondition: nums is sorted in ascending order.
* lo >= 0, hi < nums. length, nums. length > 0
*/
public static int bSearch(int[] nums, int lo, int hi, int target)
{
if (hi >= lo)
{
int mid = (lo + hi) / 2;
if (nums[mid] == target)
{
return mid;
}
if (nums[mid] > target)
{
return bSearch(nums, lo, mid - 1, target);
}
else
{
return bSearch(nums, mid + 1, hi, target);
}
}
return -1;
}
The following code segment appears in a method in the same class as bSearch.

int target = 3;
int[] nums = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};
int targetIndex = bSearch(nums, 0, nums. length - 1, target);
How many times will bSearch be called as a result of executing the code segment above?

1- A

2- B

3- C

4-D

5-E

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
