AP computer science principles exam abstraction - correct answerRemoving unnecessary details to focus on the essential characteristics. To break problems up into separate parts which can then be solved separately and recombined to form a complete solution. To focus on and use something based only on what it does and without concern for how that functionality is accomplished.Pulling out specific differences to make one solution work for multiple problems ASCII table - correct answerAmerican Standard Code for Information Interchange. ASCII is the universally recognized raw text format that any computer can understand bit - correct answerA contraction of "Binary Digit". A bit is the single unit of information in a computer, typically represented as a 0 or 1 byte - correct answera data measurement unit that contains eight bits hardware architecture - correct answerHardware uses transistors and logic gates at its lowest level hexadecimal - correct answerA number system consisting of 16 distinct symbols — 0-9 and A-F — which can occur in each place value logic gate - correct answerperform basic logical functions and are the fundamental building blocks of digital integrated circuits model - correct answerA 3D representation of a person or thing or of a proposed structure octal - correct answera base 8 number system overflow - correct answerHappen when numbers are larger than the computer can hold 1 / 2
parameter - correct answerAn extra piece of information passed to a function to customize it for a specific need procedure` - correct answerAlso called functions, reuse code is an example of abstraction Are flexible due to being able to have different values for parameters at different times round-off/rounding error - correct answerSometimes numbers are stored imprecisely and perceived results can be a bit off algorithm - correct answerA series of steps to solve a problem binary search - correct answerdivide and conquer approach Feedback about whether the value in question is higher or lower than the midpoint of the list determines which half to discard, and which half to continue searching. The dividing and searching steps are repeated until the value is found or determined that it is not in the list.boolean values - correct answercan only be true or false clarity - correct answerhow easy it is to understand models/simulations - correct answera program which replicates or mimics key features of a real world event in order to investigate its behavior without the cost, time, or danger of running an experiment in real life.linear search - correct answerSearch through a data set from one end to the other to find a value.readability - correct answerHow easy is it to read or follow correctness - correct answerAccuracy and whether or not it contains errors.
