Convert
0.625 to binary
Translate 0.625 into a fraction. We all know that 0.5 is ½. We know that the remainder, 0.125, is ⅛. Add them together, and you get ½ + ⅛ = ⅝.
Now, in binary, the positions to the right of the point are , which is ½, ¼, and ⅛ respectively.
⅝ is 5 × ⅛. 5 in binary is 101. So, ⅝ is
= 0.101
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

Answer:</h2>
Option A: Both POP3 and IMAP keep email on an email server by default.
is the correct answer.
<h2>
Explanation:</h2>
Following points will make the idea of POP3 and IMAP clear:
<h3>POP3:</h3>
- POP3 is the acronym for Post Office Protocol 3.
- POP3 is the method of receiving emails in which the emails received on the app can be downloaded on to the computer by having an internet connection.
- These downloaded emails can be viewed offline whenever needed and managed as well.
- POP3 makes it possible that the storage space of the default server do not run short as the downloaded emails are deleted from the server.
<h3>IMAP:</h3>
- IMAP stands for Internet Message Access Protocol.
- It is the method in which the mails are viewed and managed directly on the internet server instead of downloading them on the computer.
- IMAP makes sure to manage the mails so carefully and timely so that unimportant mails are deleted to make sure that the storage space does not run short.
<h3>
Conclusion:</h3>
So from these points we can make sure that both ways keep emails on email server but POP3 have option to download mails from server while IMAP dont have.
