Which Internet of Things (IoT) challenge involves the difficulty of developing and implementing protocols that allow devices to communicate in a standard fashion?

Answer:

(a) 845 = 0000 0011 0100 1101

(b) 1500 = 0011 1010 1001 1000

(c) 100 = 0000 0000 0110 0100

(d) -923 = 1111 1100 0110 0101

Explanation:

NOTES:

First Note: The question requests that the numbers be represented in word-length. That means they should be represented in 16bits (a word is 2 bytes).

Second Note: To convert a number to its 2's complement representation,

(i) if the number is positive, the usual conversion to binary will suffice. You might just need to add zero at the beginning of the sequence of bits to ensure that the leftmost bit is a zero(0).

(ii) if the number is negative, then;

=> convert the magnitude of the number to its binary

=> add zeros to the beginning of the sequence of binary until the sequence has the specified length

=> flip each bit in the sequence and add 1 to the result.

SOLUTION:

Applying the rules in the notes above, lets convert the numbers.

(a) 845 => The number is positive, conversion to its binary will suffice

2  |  845

2  |  422 R 1

2  |  211 R 0

2  |  105 R 1

2  |  52 R 1

2  |  26 R 0

2  |  13 R 0

2  |  6 R 1

2  |  3 R 0

2  |  1 R 1

2  |  0 R 1

Writing the remainders upwards, we have

845 = 1101001101

Pad with zeros to convert it to its word-length representation.

845 = 0000 0011 0100 1101

(b) 15000 => The number is also positive, so following the same step as above,

15000 = 11101010011000

Pad with zeros to convert it to its word-length representation.

15000 = 0011 1010 1001 1000

(c) 100 => The number is also positive, so following the same step as above,

100 = 1100100

Pad with zeros to convert it to its word-length representation.

100 =  0000 0000 0110 0100

(d) -923 => The number is negative;

-->  first convert its magnitude (923) to binary

923 = 1110011011

--> Pad with zeros to convert it to its word-length representation.

923 =  0000 0011 1001 1011

--> Flip the bits

0000 0011 1001 1011 = 1111 1100 0110 0100

--> Add 1 to the result above

1111 1100 0110 0100 + 1 = 1111 1100 0110 0101

Therefore;

-923 = 1111 1100 0110 0101

The word length 2's complement representations are:

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100

d. -923: 1111110001000101

We have,

To find the word-length 2's complement representation of each decimal number, we first need to determine the binary representation of the absolute value of the number and then convert it into its 2's complement form if the number is negative.

Assuming the word length is 16 bits:

a. 845:

Binary representation of 845: 0011 0100 1101

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 0100 1101

b. 15000:

Binary representation of 15000: 0011 1011 0110 0000

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 1011 0110 0000

c. 100:

Binary representation of 100: 0000 0000 0110 0100

Since it is positive, the 16-bit 2's complement representation remains the same: 0000 0000 0110 0100

d. -923:

Binary representation of 923: 0000 0011 1011 1011

To find the 16-bit 2's complement representation, we first invert all the bits: 1111 1100 0100 0100

Then, add 1 to the inverted value: 1111 1100 0100 0101

So, the 16-bit 2's complement representation of -923 is: 1111 1100 0100 0101

Thus,

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100

d. -923: 1111110001000101

Final answer:

The Java program uses a for loop to calculate the sum of the first 9 positive integers. The sum variable is increased by val each loop iteration, while val is incremented by 1. The output of the program is therefore 45.

Explanation:

The student asked about the output of a Java program with a for loop that calculates the summation of numbers. To determine the output, we can trace the loop's execution. Starting with int sum = 0, we enter the for loop, which initializes int k = 0 and will iterate until k is greater than 8. On each iteration, the current value of int val is added to sum, and then val is incremented by 1. Thus, the loop runs 9 times (from k = 0 to k = 8 inclusive) and sums the numbers 1 through 9. We end up with sum equalling the sum of the first 9 positive integers, which is 45. Hence, the output printed to the console is 45.

Program Explanation:

In the above C language program header file is included, which provides features to use basic function then the main method is defined inside this method an integer variable "i" declare, that holds a value which is "0".  In this method, the do-while loop is defined. In the do section, we print value and in the while block checks the condition which is i is less than 5.

Answer:

#include <stdio.h>

void main()

{

int i = 0;

do{

printf("%d ", ++i);

}

while (i < 5);

i=i+1;

}

}

Explanation

The #include needs to include something and that's the standard input and output which is coded has stdio.h

In the do while loop what it does is print the value of I while I is less than 5 and you increment I value so as to prevent infinite looping

Final answer:

Hackers exploit vulnerabilities using tactics like phishing, malware, and social engineering to steal sensitive data. The stolen data is used for financial gain or identity theft. Reducing hacking requires updates, security measures, and user education.

Explanation:

When evaluating the techniques that hackers use to compromise systems, one common method is by exploiting various vulnerabilities. Hackers might target vulnerabilities within software, such as outdated systems, unpatched flaws, or configuration errors.

They deploy tactics such as phishing, malware, and social engineering to trick users into giving up sensitive information or to gain unauthorized access to systems.

Among the reasons hackers engage in these activities are to steal personal data, financial information, or intellectual property. The stolen data can be used for financial gain, identity theft, or even to gain a competitive advantage.

Hackers are often quite successful due to the sophistication of their tactics and the general lack of awareness and preparedness among users. To reduce or stop hacking, it is essential to consistently update systems, implement security measures like firewalls and antiviruses, and educate users on best practices for cyber hygiene.

Answer:

c. parameters

Explanation:

Parameters are simply placeholders (sometimes called dummy variables) used mainly by methods to perform their given tasks so as to provide controlled variability in  the program(or algorithm). Sometimes they are called arguments. But then it is much more specific to simply use parameters rather than arguments because arguments are the variable values that the parameters are serving as placeholders for.

Parameters identify and describe values that are passed into a function or subroutine.

Parameters are also used for simulation and testing purposes where the input s to the program are or can be varied.

PS: Methods are just functions performed by a class in a program.
