True, the computer will read from, say, a blu-ray and then transfer it to your RAM to before writing it to your hard drive and then, through the various other wonders of computers, it can be displayed on your monitor.
Answer:
c. 4 to 6
Explanation:
According to the VMware, a virtual machine software company widely known for producing the virtualization software, which is capable of making computer hardware components to be compartmentalized into various virtual layers, recommended the best practices of virtual CPU per core to be running 4 to 6.
Hence, in this case, the correct answer is option C
Answer:
(s.charAt(0) != s.charAt(s.length()-1))
Explanation:
public class Palindrome
{
public static void main(String[] args) {
System.out.println(isPalindrome("car"));
System.out.println(isPalindrome("carac"));
}
public static boolean isPalindrome(String s) {
if (s.length() <= 1)
return true;
else if (s.charAt(0) != s.charAt(s.length()-1))
return false;
else
return isPalindrome(s.substring(1, s.length() - 1));
}
}
You may see the whole code above with two test scenarios.
The part that needs to be filled is the base case that if the character at position 0 is not equal to the character at the last position in the string, that means the string is not a palindrome. (If this condition meets, it checks for the second and the one before the last position, and keeps checking)
Answer:
C. Z-wave
Explanation:
The Z wave is a wireless communications protocol used primarily for automation. The Z- wave operates using a mesh network and then uses low energy radio waves to communicate from appliance to appliance.
The Z wave operates on a lower frequency than most other popular RF devices, thus making interference nonexistent.
The range of the Z-wave is 100m. Hence, it can give a perfect coverage from the base station to the company.
<em>Option A is wrong</em> . This is because the Zigbee is insecure and has a low coverage range (10m-20m). This means that there are possibilities of interference and also improper coverage beyond 50 m.
<em>Option B is wrong.</em> This is because Bluetooth devices are insecure, can loose connections under certain conditions. They have a range of 10m which is a lot lower than 50m benchmark.
<em>Option D is wrong</em>. NFC stands for Near Field Communication. This means its range is practically about 4cm and it cannot be used for long ranges as the company intends.
Answer:
Symmetric encryption or single key encryption
