• 22

• 37

• 41

• 82

ASCII is a character-encoding scheme that uses 7 bits (8 bits if you are using the extended ASCII table) to represent each character. The decimal (base 10) values 65 through 90 represent the capital letters A through Z, as shown in the table above.

Which ASCII character is represented by the binary (base 2) number 1000001?

• A

• B

• C

• D

• RLI

What is Abstraction?

• (A) Complexity made simple

• (A) Step by step instructions

• (A) Mathematical operations

• (A) Breaking data

Why is IP v4 going to be replaced by IP v6?

• IP v6 is easier to use.
• IP v4 does not work on old hardware.
• IP v4 was not encrypted.
• We are running out of IP v4 addresses.
