Review this excerpt from a hex viewer. You can assume that all data shown is in hex. You can assume that two's complement is used to store signed integers with a 16-bit architecture which is byte addressable. Refer to this excerpt to answer the questions below:

0000007B00 8B00 ACA1 37AE 6A00 3202 9015 AD34

000010 0218 6D30 028D 3402 AD35 8802 3102 8D35

000020 0E30 0290 DAEE 3102 4C00 0200 0040 004A

Hex Viewer Questions:You must show your work as to how you got the answer. 1. Refer to the first byte of memory shown above, address 000000. Assume that this byte is used to store an 8-bit unsignedinteger. Write the decimal value stored in this byte. Show your work.

2. Refer to the third byte of memory shown above (8B). Assume that this byte holds a signed8-bit integer. What is the decimal value of this byte? Show your work.

• 8B00 8421

1000 1011 =

3. Refer to the fifth byte of memory shown above (AC). Convert this value to octal. Show your work.

• 37AE

11 011 110 101 110

3 3 6 5 6

4. Refer to the sixth byte of memory shown above (A1). Use XOR with a mask to set all bits to 0. Be sure to show the mask used.

• 
  

5.Refer to the seventh byte of memory shown above (37). Use OR with a mask to set all bits to 1. Be sure to show the mask used.

6.Refer to the eighth byte of memory shown above (AE). Use AND with a mask to set all bits to 0. Be sure to show the mask used.

7.Refer to the ninth byte of memory shown above (6A). Add the value 5C to that number. Give your answer in binary. Show your work.

8.Refer to the last byte of memory shown above (4A). Convert this byte intoan alphabetic character. Assume that ASCII (UTF-7) is used. (Hint: The character 'A' is 0100 0100)

9.Refer to the first byte of memory shown above (7B), perform a left shift of 2 bits. Show your work.

10. Notice that on the second line (in the latter half of the second line) there is a byte with the value 0x88. This is the only byte with that value in your memory dump. What is the address of the byte with the value 0x88?

11. If an entire alphabet consists of 14 different characters, and given that the first character of that alphabet table starts at binary value 0000 0001₂,what is the binary value for the last character? Give your answer in binary.

12. If an entire alphabet consists of 45 different characters, how many bits are required to represent that alphabet?

13. Identify each gate below.
