A simple sketch of an idea or model for something new. It’s the original drawing from which something real might be built or created.

It refers to facts provided or learned about something or someone / It is data as processed, stored, or transmitted by a computer / It is the answer to a question.

A set of rules governing the exchange or transmission of data between devices.

A way of representing information using only two options.

A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1

8 bits

It’s the numerical value that a digit has by virtue of its position in a number.

Error from attempting to represent a number that is too large.

Error from attempting to represent a number that is too precise. The value is rounded.

A simplified representation of something more complex. They allow you to hide details to help you manage complexity, focus on relevant concepts, and reason about problems at a higher level

American Standard Code for Information Interchange; the universally recognized raw text format that any computer can understand.

A type of data used for graphics or pictures.

It is data that describes other data. For example, a digital image may include metadata that describes the size of the image, number of colors, or resolution.

short for "picture element", the fundamental unit of a digital image, typically a tiny square or dot that contains a single point of color of a larger image.

Data with values that change continuously, or smoothly, over time. Examples of it include music, colors of a painting, or position of a sprinter during a race.

Data that changes discreetly through a finite set of possible values

A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.

This color model uses varying intensities of (R)ed, (G)reen, and (B)lue light added together to reproduce a broad array of colors.

A process for reducing the number of bits needed to represent something without losing any information. This data compression algorithm allows the original data to be perfectly reconstructed from the compressed data. This process is reversible.

A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This data compression method uses inexact approximations, discarding some data to represent the content. Most commonly seen in image formats like .jpg. This process is not reversible.

a problem solving approach (algorithm) to find a satisfactory solution where finding an optimal or exact solution is impractical or impossible.

A work or invention that is the result of creativity, such as a piece of writing or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc.

 It is the exclusive legal right that a creator has to reproduce, publish, sell, or distribute his/her intellectual property (literary, musical, or artistic work).

A collection of public copyright licenses that enable the free distribution of an otherwise copyrighted work, used when an author wants to give people the right to share, use, and build upon a work that they have created.
