AP CSP exams questions and answers
Algorithm - -A precise sequence of instructions for processes that
can be implemented in a programming language and executed by
a computer.
-Control Structure - -one or more programming language
statements that control the flow of a computer program.
Examples: If/Else structure or a loop structure.
-Computer - -a machine that processes information under the
control of a program.
-Program - -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 - -the computer's electronic and mechanical
components.
-Software - -the programs that control computers
-General purpose computer - -a computer that can run many
different programs (e.g. a smartphone).
-Special purpose computer - -a computer that has a fixed program
( e.g. a calculator, a watch, a car's brakes)
-Memory - -physical device used to store information for use in a
computer or other digital electronic device( e.g. disk drive, flash
drive)
-RAM - -Random Access Memory- also called main memory stores
the computer's programs and data temporarily while power is on.
-CPU - -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 - -bring data and programs into the computer (e.g.
mouse, keyboard)
-Output devices - -transmit data to other computers to users (e.g.
printer, monitor, speaker)
-Motherboard - -houses the computer's main electronic
components
-Chips - -the computer's electrical components are composed of
these very tiny integrated circuits.
-Integrated circuit - -packed with millions of electronic
components
-Bit - -a binary digit, the smallest unit of data, a 1 or a 0.
-Byte - -is equal to 8 bits.
-High-level language - -a programming language that is human
readable (app inventor) and provides the programmer with easy
to understand abstractions.
-Machine language (or low-level language) - -a programming
language that is machine readable (binary code), closer to the
machine hardware and provides abstractions that are difficult for
the programmer to understand.
-Compiler - -a software that translates source code (human
readable) into binary code.
-Applications - -program or group of programs designed for end
users such as Firefox, Excel, Word, etc.
