Test Corrections

I scored 46/50. I got questions 5, 6, 42 and 44 wrong.

Q5

Q6

Each packet contains a portion of the data to be transmitted, along with metadata containing information used for routing the data. This metadata includes the source and destination addresses, as well as other information that is used by routers to determine the most efficient path for the packet to take to reach its destination. Once the packets reach their destination, they are reassembled in the correct order to reconstruct the original data.

Q42

Obtaining part of a text file is not useful when attempting to determine whether a word appears in two text files. Two calls to this procedure can be used to determine if a particular word appears in each of two text files. If both calls return true, then the word appears in both text files.

Q44

Since the student cannot modify the search procedure’s code or internal abstractions, the argument passed to the search procedure must be a word, not a definition. The student knows that the procedure searches for a value without knowing how it does the searching. This is an example of the use of procedural abstraction.

Reflection

I am not very comfortable with the questions about networking, mainly. I am mostly comfortable with the questions differentiating data and metadata. Identifying procedures is sometimes confusing to me, but I do understand after knowing the answer. I will study and watch the CB videos about networking.
