MSD means Most Significant Bit.

Suppose 1010.
MSD-1.
LSB-0.

@All.

Here is the Example: 260.06 here 2 is the MSD.

Before I introduce the number systems that are more commonly used in electronics lets discuss a number system that we all are aware of and which we use it everyday.
The Decimal number system got its name because it uses 10 symbols (or popularly digits) for counting and performing operations. It uses the digits 0 to 9.
In this number system, the radix or the base is 10 since the number of digits used is ten. The general format of decimal number representation is shown below

104 --- 103 --- 102 --- 101 --- 100 --- 10-1 --- 10-2 --- 10-3 --- 10-4 ---> Weights
S4 --- S3 --- S2 --- S1 --- S0 --- S-1 --- S-2 --- S-3 --- S-4

Where,
MSD is a most significant digit (leftmost digit of a number)
LSD is the least significant digit (rightmost digit of a number)

Note: From this, we can observe that the MSD has the greatest weight and the LSD have the smallest weight.

MSD means most significant digit. It has the highest weight.

This is because as already been said MSB is the most significant bit, so it holds the most weight and moreover for writing any bit we move from LSB to MSB.

In digital the weight-age of a bit is given by.

2^n i.e. if we start with left most digit it has highest weight.

32 16 8 4 2 1. Now we assume a number in binary is 11011.

So the MSB in this is left most 1 with weight 16 and LSB is right most bit with weight 1.

We know that MSB is the most significant bit, it holds the leftmost bit value and it most weight.

MSB is nothing but most significant bit.

EX: 11000.

'1' is the msb.

'0' is the lsb.

1110011.00101.

Tell what is msd and lsd in this number?

Sweta Verma said:   9 years ago
Msd = 1 and lsd, = 1.
