Explanation / Answer

1. In the chart given in the question go to the character 'h' under the column Char and then check the hex column corresponding to the character 'h' . We find that it is 68, we look only at the hex column because in the main memory the hex code of the characters are stored(recognized by 0x in front of the numbers). Now, in the main memory table, the address of 0x68 is 0x20183019.

So, the answer is , the address of character h is 0x20183019.

2. Now, we first look at the main memory table. In the table we find the corresponding hex code to the address 0x20183011(given in question). We find it is 0x54. Now we find the character corresponding to the hex code 54 in the table given below. We find it is T.

So,the answer is, the firts character string starting from 0x20183011 is T.
