Answer:
Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}
H(X)=5.4224 bits per symb
H(X|Y="not C")=0.54902 bits per symb
Explanation:
P(B)=2P(C)
P(A)=2P(B)
But
P(A)+P(B)+P(C)=1
4P(C)+2P(C)+P(C)=1
P(C)=1/7
Then
P(A)=4/7
P(B)=2/7
Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}
iii
If X={A,B,C}
and P(Xi)={4/7,2/7,1/7}
where Id =logarithm to base 2
Entropy, H(X)=-{P(A) Id P(A) +P(B) Id P(B) + P(C) Id P(C)}
=-{(1/7)Id1/7 +(2/7)Id(2/7) +(4/7)Id(4/7)}
=5.4224 bits per symb
if P(C) =0
P(A)=2P(B)
P(B)=1/3
P(A)=2/3
H(X|Y="not C")= -(1/3)Id(I/3) -(2/3)Id(2/3)
=0.54902 bits per symb
<span>What is a sending device? </span>
A sending device is a device that initiates an instruction to transmit data, instructions or information.
The statement that correctly describes the difference between an IP address and a MAC address for a specific device is that the IP address can change, but the MAC address always stays the same.
For better understanding, let us explain what the IP address and a MAC address means
- IP address simply mean Internet protocol address
, it is a distinct string of numbers that is often separated by full stops that shows each computer using the Internet Protocol to link or communicate over a network.
- MAC address is simply regarded as a A distinct number also as it shows a device or computer that is linked or connected to the internet.
- One of the major difference between a MAC address and an IP address? is that the IP address gives the location of a device on the internet but the Mac address identifies the device connected to the internet.
from the above, we can therefore say that the answer The statement that correctly describes the difference between an IP address and a MAC address for a specific device is that the IP address can change, but the MAC address always stays the same, is correct
