MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In a binary number, the bit furthest to the left is called the most significant bit (msb) and the bit furthest to the right is called the least significant bit (lsb). The MSB gives the sign of the number (sign bit), 0 for positive and 1 for negative. The remaining bits hold the magnitude of the number.

Detailed explanation-2: -In computer science, the sign bit is a bit in a signed number representation that indicates the sign of a number. Although only signed numeric data types have a sign bit, it is invariably located in the most significant bit position, so the term may be used interchangeably with “most significant bit” in some contexts.

Detailed explanation-3: -The most significant bit (MSB) is the bit in a multiple-bit binary number with the largest value. This is usually the bit farthest to the left, or the bit transmitted first in a sequence. For example, in the binary number 1000, the MSB is 1, and in the binary number 0111, the MSB is 0.

Detailed explanation-4: -For signed binary numbers the most significant bit (MSB) is used as the sign bit. If the sign bit is “0”, this means the number is positive in value. If the sign bit is “1”, then the number is negative in value.

Detailed explanation-5: -Signed integers are numbers with a “+” or “-“ sign. If n bits are used to represent a signed binary integer number, then out of n bits, 1 bit will be used to represent a sign of the number and rest (n-1)bits will be utilized to represent magnitude part of the number itself.
