Answer to Question 1

2
Rationale: Binary code is a series of 1s and 0s called bits, and one byte contains 8 bits. The binary system is positional with each position's value increasing by the power of 2.
The right most position value is 20 or 1 and continuing to the left the values would be 21 = 2, 22 = 4, 23 = 8 and so on. The Arabic number represented is the sum of the powers of 2 represented by the 0s and 1s. The sum of the powers of binary 00001000 is 0 + 0 + 0 + 0 + 8 + 0 + 0 + 0 = 8, so the correct choice for representing the Arabic number 8 is the binary code 00001000. The binary code 1000 represents the Arabic number 8 but is not a byte.

Answer to Question 2

1
Rationale: Correct. A CPO is mandated by federal legislation to protect personal health information of patients; this includes both paper and electronic information. CPO duties include strategic planning, information security, and overall management of the information system. A webmaster is responsible for the design, maintenance, and security of materials placed on the Internet. The security officer's duties include assigning and monitoring system access identification codes and passwords.
