Answer:

Option (c) NFC

Explanation:

  • The NFC Technology is a Wireless Technology which works in the range of 10 cm or less.
  • NFC stands for Near Field Communications.
  • The name itself indicates that it a communication mode with the near by objects.
  • The NFC technology is used in Access Cards, Payment Cards and Mobile Devices etc.
  • Option (a) IM - Instant Messaging is the instant text messaging technology sends and receives messages over the internet. It is used in Social Media where instant messaging is available. So, option (a) is not correct option.
  • Option (b) text messaging the technology is the technology in which the text messages are sent over the mobile networks ( in case of text messaging in mobile phones ) or over the internet ( emails, blogging etc). So, option (b) is not correct option.

Develop an sec (single error correction) code for a 16-bit data word. generate the code for the data word 0101000000111001. show
Kipish [7]

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields 2^{k} - 1 > = M+K, where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position              number              Check bits            Data Bits

21                                   10101

20                                  10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

// Getting the input entered by the user

System.out.print("Enter a number :");

n = sc.nextInt();

// calling the method by passing the user entered input as argument

dashedLine(n);

}

//This method will print the dashed line for number greater than zer

private static void dashedLine(int n) {

if (n > 0) {

for (int i = 1; i <= n; i++) {

                   "8": "Eight",

                   "9": "Nine",

                   "10": "Ten"}

 

# Handle cases when 10 comes in input

if len(cardNotation) == 3:

 

   number = cardNotation[:2]

   color = cardNotation[2:]

   print cardNumberValues.get(number) + " of " + cardColors.get(color)

 

elif len(cardNotation) == 2:

 

   number = cardNotation[:1]

   color = cardNotation[1:]

   print cardNumberValues.get(number) + " of " + cardColors.get(color)
