Explain the difference between MSB and LSb.

Solution

MSB: Most Significant Bit and LSB: Least Significant Bit

In a digital data bit string, the MSB is a bit of the highest digit, and the LSB is a bit of the lowest digit.They are just the names of two specific bits in a binary number. The least significant bit is the one which is written leftmost, and the most significant bit is the one which is written rightmost.

Example:

The number 99 in binary is 01100011. The least significant bit is 1 (from 0110001[1]), and the most significant bit is 0 (from [0]1100011).

In many signed binary representations the most significant bit determines the sign of the number (positive or negative). In signed magnitude the most significant bit is the sign (0 = positive, 1 = negative) and the remaining bits give the magnitude of the number. In two\'s complement, which is the most widely used signed representation, the most significant bit also determines the sign of the number.

Some important uses for the lsb are hash functions and checksums. A hash function is a function that can be used to assign an index value to digital data, enabling faster lookups of items in a database or a large table.

Considering inter-block interfaces, with a parallel interface, all the bits on the transmitting side and the receiving side correspond, so there is no problem in particular. However, with a serial interface, all the bits are transmitted and received through a single data line, so that the bit order definitions in the protocols of the transmitting side and the receiving side must match. In the case of the above data (number), the data is transmitted and received in the order of \"01100011\" in the case of MSB first, and in the order of \"11000110\" in the case of LSB first. As long as the receiving side matches the transfer mode (MSB first or LSB first) with the transmitting side, parallel data can be reproduced through serial-parallel conversion of the receive data.

In some of the cases least significant bit can be used to determine if a number is even or odd. If it is 0 the number is even, and if it is 1 the number is odd. The least significant bit of 01100011 is 0, which means 99 is odd.
