Computer Science

What is an Computer Functions ?

• gathers data, allows users to input data.

• Input, Output, Process, Storage.

What is a computer Output ?

• displays data and information for user.

• Input, Output, Process, Storage.

• representation of fact, figure, or idea.

What is a Input ?

• gathers data, allows users to input data.

• displays data and information for user.

Examples of Input Devices

• CPU, ROM, RAM and cache, Slots for expansion cards

• monitors, printers, speakers and earphones

• keyboard, mouse, microphone, stylus, scanner, camera

Algorithm

• Pulling out specific differences to make one solution work for multiple problems.

• A list of steps to finish a task. A set of instructions that can be performed with or without a computer. For example, the collection of steps to make a peanut butter and jelly sandwich is an algorithm.

• Mental processes and strategies that include: decomposition, pattern matching, abstraction, algorithms (decomposing problems into smaller, more manageable problems, finding repeating patterns, abstracting specific differences to make one solution work for multiple problems, and creating step-by-step algorithms).

DEFINE: Command

• An instruction for the computer. Many commands put together makeup algorithms and computer programs.

• A way of representing information using only two options.

DEFINE: Computational Thinking

DEFINE: Computer Science

• Computer science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate, store, and communicate digital information.

• A way of representing information using only two options.

• The visual programming language used in Code.org's online learning system for K-5 students.

• the study of the principles and use of computers.

The smallest unit of information is ?

• a byte (Pronounced: bite)

• a bit

• a nibble

• a block

• Fortran

Which programming language is most commonly used for complex scientific programming?

• BASIC

• Cobol
