CSP Practice AP Exam A binary question is defined as a. A piece of information that is sent in pairs b. Two questions which share the same answer c. A message which has two possible states d. A question which can be answered in only one of the two possible ways - D A binary message consisting of four bits was sent to you by a friend. The message was supposed to be ABAB. Unfortunately your friend sent the bit on the wire once every 2 seconds, but you read the wire once every second. Assuming that the first bit was sent and read at the same time, what message did you receive instead? a. ABAB b. AABB c. AAAA d. BBBB e. ABBB - B When sending a response to a question with four possible answers, the most efficient method will require no more than how many bits? a. 5 bits b. 4 bits c. 3 bits d. 2 bits e. 1 bit - D If you had two different shapes ( a circle and a square) how many 3 place patterns can you make? a. 4 b. 6 c. 8 d. 10 e. 12 - C What is the minimum number of bits you will need to encode the 26 letters of the alphabet plus a space? a. 2 bits b. 3 bits c. 4 bits d. 5 bits e. 6 bits - D A standard QWERTY keyboard has 47 characters that can place characters on the screen. Each of these keys can also display a second character by holding the "Shift" key at the same time. How many bits would you need to encode everything that could be typed on this keyboard? a. 3 bits b. 4 bits c. 5 bits d. 7 bits e. 12 bits - D ASCII is an acronym for a. American Standard Cryptography Information Instruction b. American Standard Code for Information Interchange c. American Standard Cipher for Information Instruction d. None of the above - B ASCII has an encoding for every character of the alphabet as well as encodings for numbers-- that is encodings for the symbols of the digits 0 - 9. How many bits are required to store the text of the number "200" in ASCII? a. 3 bits b. 8 bits c. 16 bits d. 24 bits e. 32 bits - D The Internet is composed of many layers. Higher level layers depend on the functionality of the lower levels without worrying about precisely how those layers work. These layers in order from lower to higher are: a. Physical network, IP, TCP b. IP, Physical network, TCP c. TCP, IP, Physical network d. Physical Network, TCP, IP - D The Internet Engineering Task Force (IETF) defines the protocols and standards for how the Internet works. The members of the IETF are: a. An international coalition of government agencies who oversee the Internet in their countries b. The worldwide leaders of the Tier 1 internet service providers c. A loosely organized collection of citizens and engineers who communicate mostly by email d. Political leaders and heads of state e. There are no members. IETF is an "organization" in name only - C What is an RFC? a. Restricted Fiduciary Contract b. Request for Comments c. Radio Frequency Controller d. Related Fundamental Content e. ReFactored Code - B If I understand how the Internet works then I will be able to : (two correct responses)
