AP CSP Questions with Detailed Verified
Answers
Algorithm ANSWER: A precise sequence of instructions for processes
that can be implemented in a programming language and executed by
a computer.
Control Structure ANSWER: one or more programming language
statements that control the flow of a computer program. Examples:
If/Else structure or a loop structure.
Computer ANSWER: a machine that processes information under the
control of a program.
Program ANSWER: sequence of instructions that control the computer.
To run, it must be loaded into the computer's memory where the CPU
executes it one instruction at a time.
Hardware ANSWER: the computer's electronic and mechanical
components.
Software ANSWER: the programs that control computers

General purpose computer ANSWER: a computer that can run many
different programs (e.g. a smartphone).
Special purpose computer ANSWER: a computer that has a fixed
program ( e.g. a calculator, a watch, a car's brakes)
Memory ANSWER: physical device used to store information for use in a
computer or other digital electronic device( e.g. disk drive, flash drive)
RAM ANSWER: Random Access Memory- also called main memory
stores the computer's programs and data temporarily while power is on.
CPU ANSWER: Central Processing Unit is the hardware that carries out
the instructions of a computer program. It is made up of 3 main parts:
the control unit (CU), the arithmetic and register. The CU processes the
program's instructions, the ALU (arithmetic logic unit) performs the
arithmetic and logic operations and the register stores intermediate
data during program execution.
Input devices ANSWER: bring data and programs into the computer (e.g.
mouse, keyboard)
Output devices ANSWER: transmit data to other computers to users (e.g.
printer, monitor, speaker)
