Explain why we cannot bit-stuff in character-oriented framing to change a flag byte appearing in the text.

- Manchester encoding guarantees frequent clock synchronization by changing signal values. What is the maximum number of bits which may be encoded without a signal change? (Note: The way this question has been asked. you are not to include the bit which includes a signal change in your count)An 8-bit byte with binary value 10101111 is to be encoded using an even-parity Hamming code. What is the binary value after encoding? ANS: The encoded value is 101001001111 Why is this answer longer from binary value? Please solve this question with details. Please explain why you use that method.Floating-Point Representation. What is the floating-point value for binary 4. a) 11000010100000 using the simple model (14-bit format, 5 bits for the exponent with a bias 15, a normalized significand of 8 bits, and a single sign bit for the number)?
- Explain the term masking. How is it useful for data representation? Explain the concept using an example For a floating-point format with a k -bit exponent and an n -bit fraction, give a formula for the smallest positive integer that cannot be represented exactly (because it would require an n + 1 –bit fraction to be exact).Determinethe Decimal Value (Base 10) of the following IEEE-754 32-bit floating-point representation. Show your working. (Hint: identify the sign bit, the biased exponent and the trailing significand /mantissa). 0 01111111 110 0000 0000 0000 0000 0000Write down the bit pattern in the fraction of value 1/3 assuming a fl oating point format that uses binary numbers in the fraction. Assume there are 24 bits, and you do not need to normalize. Is this representation exact?
- If the floating-point number representation on a certain system has a sign bit, a 3-bit exponent and a 4-bit significand: What is the largest positive and the smallest positive number that can be stored on this system if the storage is normalized? (Assume no bits are implied, there is no biasing, exponents use two's complement notation, and exponents of all zeros and all ones are allowed.) What bias should be used in the exponent if we prefer all exponents to be non-negative? Why would you choose this bias?To represent real binary numbers in floating point notation, we use a 14-bit format with 1 bit for the sign, 5 bits for the exponent, and 8 bits for the significand. Assuming an excess-16 exponent bias, and no implied 1 bit to the left of the radix point, the negative binary (real) number -0.0000100101 is represented as O 11010010010100 O 11110010010100 O 10110010010100 O 00110010010100Suppose we have just found yet another representation for floating-point numbers. Using this representation, a 12-bit floating- point number has 1 bit for the sign of the number, 4 bits for the exponent, and 7 bits for the mantissa, which is normalized as in the simple model so that the first digit to the right of the radix points must be a 1. Numbers in the exponent are in signed two's complement representation. No bias is used, and there are no implied bits. Show the representation for the smallest positive number this machine can represent using the following format (simply fill in the squares provided). What decimal number does this equate to? Sign Exponent Mantissa
