AP Computer Science Vocabulary Set #2

If Else Statement

• a more thorough version of an if statement that stipulates what is to

  happen when a certain criteria is not met.

• type of selection statement that only executes when a certain criteria is

  met.

• binary values (usually denoted true and false), intended to represent

  the truth values of logic and Boolean algebra.

• algorithmic structure that uses "if...then" to tell computer how to select a

  step or to tell the sequence that should be executed.

If Statement

• (repetition) - one complete step of a loop, repeated until a certain condition

  is met

• type of selection statement that only executes when a certain criteria is

  met.

• a more thorough version of an if statement that stipulates what is to

  happen when a certain criteria is not met.

• algorithmic structure that uses "if...then" to tell computer how to select a

  step or to tell the sequence that should be executed.

Input

• Information sent to the computer by the user, in the form of letters, numbers, or

  symbols.

• logic structure where instructions are executed in order, one after another,

  one at a time. Often called linear.

• The rules that define the written structure of a programming language.

• The software that supports a computer's basic functions, such as

  controlling computer memory, scheduling tasks, and running applications.

Iteration

• (repetition) - one complete step of a loop, repeated until a certain condition

  is met

• (iteration) - one complete step of a loop, repeated until a certain condition

  is met

• algorithmic structure that uses "if...then" to tell computer how to select a

  step or to tell the sequence that should be executed.

• type of selection statement that only executes when a certain criteria is

  met.

Loop

• program instructions that are executed one at a time, in order.

• where different logic structures sequence, selection and loops are combined

  or nested in one another.

• the repetition of some code

• (repetition) - one complete step of a loop, repeated until a certain condition

  is met

Main Memory

• Short term, temporary memory. When computer is powered off, all

  information here is lost.

• developed by Gordon Moore, who accurately predicted that the number

  of transistors that could fit on a chip would roughly double every one to two years. This

  law has helped innovators predict and develop technology efficiently for the past 50

  years.

• The software that supports a computer's basic functions, such as

  controlling computer memory, scheduling tasks, and running applications.

• Long term memory, or storage. Preserved when a computer is

  powered off.

Moore's Law

• developed by Gordon Moore, who accurately predicted that the number

  of transistors that could fit on a chip would roughly double every one to two years. This

  law has helped innovators predict and develop technology efficiently for the past 50

  years.

• Digital information displayed or sent to the user by the computer, in a form

  that humans can interpret (sound, video, text, etc.).

• Programs that run on hardware.

• Variable - A

Nesting

• The physical machine; any part of a computer that you can touch.

• Information sent to the computer by the user, in the form of letters, numbers, or

  symbols.

• Short term, temporary memory. When computer is powered off, all

  information here is lost.

• where different logic structures sequence, selection and loops are combined

  or nested in one another.

Operating System

• The software that supports a computer's basic functions, such as

  controlling computer memory, scheduling tasks, and running applications.

• program instructions that are executed one at a time, in order.

• Information sent to the computer by the user, in the form of letters, numbers, or

  symbols.

• a simple diagram with symbols showing the "flow" of a process

Operators

• symbols that imply a comparison in conditional selection statements.

• The software that supports a computer's basic functions, such as

  controlling computer memory, scheduling tasks, and running applications.

• A name for a spot in the computer's memory where information can be

  stored.

• instruction in a computer program that can cause a computer to begin

  executing a different sequence of instructions.
