Activities

1 - Write your name in binary.

1. 1. First figure out the binary for each character using the chart on Representing Characters.

   2. Keep each byte (8 bits) separated by a space. For instance, "homework" would be:

      1. 01101000 01101111 01101101 01100101 01110111 01101111 01110010 01101011

   3. How many bits is your name?

   4. How many bytes is your name?

2 - Explain the benefits of using two's complement

Explain

• Relate cause and effect.

• Make the relationships between things evident.

• Provide why and/or how.

3 - What is -7 in 4-bit two's complement binary?

More Thinking: If 10 is 00001010 in an 8-bit system, what would -10 be in an 8-bit system using two's complement?

4 - How would you represent 170 in both binary and hexadecimal?

Hint

The table on the previous pageDecimal to Hexadecimal to Binary is missing some numbers, but you can look at the logic to work it out.

5 - Explain how to count upwards one-by-one in binary AND hexadecimal. Provide examples to support your answer.

Hint

Look back at question 4 and how you worked it out. Consider the logic of the table on the previous pageDecimal to Hexadecimal to Binary - how do you count upwards one by one?
