## Exercise: Hexadecimal Conversion and Memory Location Analysis ### Questions 1. **Convert the decimal integers below into a hexadecimal number.** (3 points total) - a. 321 - b. 1023 - c. 100632 - d. 15 - e. 30 2. **The following words are contained completely of hexadecimal symbols. Convert each word to its decimal value representation.** In these problems an “S” is a “5”, an “I” is a “1”. (2 points) - a. SIDE - b. BEE - c. DEEDED - d. DAB 3. **Find the sum of the following pairs of hexadecimal numbers.** (2 points) - a. 1AE + BBC - b. 20CBA + A01 - c. ABCDE + 1111 - d. E000E + BAAA 4. **What letter is at memory location 0x000F?** (1 point) 5. **At memory location 0x0093 you can find the letter "J". It's the first letter in the word Jabberwock.** Using the ASCII Code chart (find on the Internet) you can see that the letter “J” is represented by the hexadecimal 0x4A. For each of the following words give the memory location of the first letter in each word and the hexadecimal code for that letter. Be careful to note that upper and lower case letters have different hexadecimal codes. (3 points) - Jujub - vorpal - uffish - snicker - beamish - frabjous 6. **How many spaces (ASCII code 0x20) appear from memory location 0x0000 to 0x002F?** (1/2 point) 7. **What is the two byte integer stored at memory location 0x52?** (1 point) 8. **The poem and file end exactly at hex location 0x034F. Thus you can see that the file has 0x034F bytes in it. How many bytes is that in decimal?** (1/2 point) 9. **What English words start at the following memory locations?** (2 points) -
