4 digit we can store. Because bcd means binary code decimal. This value should be (0-9).

Since bcd is the values ranging from 0-9 their equivalent binary can hold 4 bits. Hence we can store 4 bits.

I have problem calculating this number system. Can someone help me understand it before I will go for my exams?

Solve properly, this sum and give an explanation.

Binary has 10 values that ranging from (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).

So add 2+2+2+2=8 (because it's binary no so that's what we add 2).

It's value is up to 9. Eventually we get the value '8' which is less than 9. Final answer is 4.

In BCD used on 4-bit.

The reason is because a BCD should be able to represent all the digits (0-9).

The largest digit (9) needs for bits (1001). That's why 4 bits are needed for BCD.

BCD means Binary Coded Decimal. It stores 4-bit digit as it ranges from 0-9.
