He following is a string of ASCII characters whose bit patterns have been converted into hexadecimal for compactness: 4A EF 68 6

almond37 [142]

Answer:

a) Please see below as the answer is self explanatory.

b) odd parity.

Explanation:

As the hexadecimal system, has as its base the decimal 16, which is the 4th power of 2 (base of the binary system), each hexadecimal digit can be expressed of a linear combination of 4 binary digits, as follows:

Hex = b₃*2³ + b₂*2² + b₁*2¹ + b₀*2⁰, where bₙ = 0 or 1.

So, we can convert the hexadecimal bit pattern to binary, as follows:

4A = 01001010

Now, if the leftmost bit is a parity bit, the ASCII code is represented by the 7 rightmost bits:

⇒ ASCII = 1001010 = 74

Repeating the same process for the remaining pairs of hex digits, we have:

EF = 11101111 ⇒ ASCII = 1101111 = 111

68 = 01101000 ⇒ ASCII = 1101000 = 104

20 = 00100000 ⇒ ASCII = 0100000 = 32

C4 = 11000100 ⇒ ASCII = 1000100 = 68

EF = 11101111 ⇒ ASCII = 1101111 = 111

E5 = 11100101 ⇒ ASCII = 1100101 = 101

b) Due to any pair of digits has an odd number of 1s, the parity used is odd parity.

Assume that name and age have been declared suitably for storing names (like "Abdullah", "Alexandra" and "Zoe") and ages respect

Irina18 [472]

Answer:

import java.util.Scanner;

public class num2 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter Name");

String name = in.next();

System.out.println("Enter Age");

int age = in.nextInt();

System.out.println("The age of "+name +" is "+age);

}

Explanation:

Java programming language is used to write the code.

The scanner class is used to prompt and receive values for name and age which are stored in the appropriate variables.

The key idea here is using string concatenation in the output statement in order to print the desired output

Which of the following is a reason photographing animals can be difficult?

erma4kov [3.2K]

They always move, so its hard catching them still, and if they are in action, you can't get a good picture because it will come out blurry. Hope this helps. Let me know if you need anything else.
