Question

PLEASE HELP ASAP WILL GIVE 100 POINTS!!!!

Suppose a packet that is transmitted across the internet contains the following information (from left to right):


Bits 1-4: Packet sequence number within the message.

Bits 5-8: Total number of packets in the message.

Bits 9-16: Number identifying the sender.

Bits 17-24: Number identifying the receiver.

Bits 25-64: Part of the actual message being sent.


Here is one of the packets being sent over the internet:

01111011 10000001 11001110 01010110 00111100 10011100 11100010 10001111


Which of the following statements about this packet is true? Select one answer


A)This is packet 1 out of 8 total packets in the message.

B)This is packet 7 out of 11 total packets in the message.

C)This is packet 14 out of 22 total packets in the message.

D)This is packet 123 out of 129 total packets in the message.

Answer 1

According to the given information about the packet format, we can determine the packet sequence number within the message and the total number of packets in the message from bits 1-8.

In the given packet, bits 1-4 are 0111, which represents the packet sequence number within the message. Bits 5-8 are 1011, which represents the total number of packets in the message.

Therefore, this packet is packet 7 out of 11 total packets in the message.

So, the correct answer is B) This is packet 7 out of 11 total packets in the message.

Answer 2

Answer:Therefore, the correct answer is B) This is packet 7 out of 11 total packets in the message.

Explanation:Using the given information, we can decode the packet as follows:

Bits 1-4: 0111 -> Packet sequence number within the message is 7.

Bits 5-8: 1011 -> Total number of packets in the message is 11.

Bits 9-16: 00000001 -> Number identifying the sender is 1.

Bits 17-24: 11001110 -> Number identifying the receiver is 206.

Bits 25-64: 01010110 00111100 10011100 11100010 10001111 -> Part of the actual message being sent.
