Answer: 1
Explanation:
a woman is born with about 1-2million ova, during puberty this figure reduce to between 600,000 and 1million. during her child bearing years the figure drops down to about 300,000 to 400,000 ova, out of which only about 500 would be ovulated during her reproductive years. the rest die out during menopause.
Answer:
a) Yes
b) Yes
c) Yes
d) No
e) Yes
f) No
Explanation:
a) All single-bit errors are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.
b) All double-bit errors for any reasonably long message are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
c) 5 isolated bit errors are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.
It produces nearly 100 % of error detection.
d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.
Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.
Answer:
a. 6 bits
b. 1
Explanation:
Ans (a)
40 Characters need to be represent by binary coded Zebronian (BCZ) , So You will need 6 bits.
5 bits wold only give you 32 = 2 x 2 x 2 x 2 x 2 unique characters.
So 6 bits would allow you to represent 64 characters.
Ans(b)
BCD = Binrary Coded Decimal is very common in electronics, particularly it displays numerical data.
BCD Encodes each digit of a decimal number into 4 digit binary form.
Each decimal digit is indiviidually converted to oits binary equivalent
For Example : 146 , the decimal degits are replaced by 0001 , 0100 and 0110 respectively
