Answer
Binary representation of 'A' in ASCII will be binary representation of its code point 65.
Converting 65 to binary:
| 2 | Quotient | Remainder |
|---|---|---|
| 2 | 65 | 1 (LSB) |
| 2 | 32 | 0 |
| 2 | 16 | 0 |
| 2 | 8 | 0 |
| 2 | 4 | 0 |
| 2 | 2 | 0 |
| 2 | 1 | 1 (MSB) |
| 0 |
Therefore, binary representation of 'A' in ASCII is 1000001.
Converting 65 to Hexadecimal:
| 16 | Quotient | Remainder |
|---|---|---|
| 16 | 65 | 1 |
| 16 | 4 | 4 |
| 0 |
Therefore, hexadecimal representation of 'A' in ASCII is (41)16.
Similarly, converting 97 to binary:
| 2 | Quotient | Remainder |
|---|---|---|
| 2 | 97 | 1 (LSB) |
| 2 | 48 | 0 |
| 2 | 24 | 0 |
| 2 | 12 | 0 |
| 2 | 6 | 0 |
| 2 | 3 | 1 |
| 2 | 1 | 1 (MSB) |
| 0 |
Therefore, binary representation of 'a' in ASCII is 1100001.
