| 11224550939 | Heuristic | heuristic a problem solving approach (typically an algorithm) to find a satisfactory solution where finding an optimal or exact solution is impractical or impossible. | 0 | |
| 11224557117 | Lossless | This form of compression is reversible and does not lose any bits or quality in the processes of encoding or decoding. | 1 | |
| 11224557118 | Lossy | This form of compression is irreversible. It greatly decreases the size of the file, but loses the original bits through the process of encoding. | 2 | |
| 11224573326 | Kilobyte | 1,000 bytes | 3 | |
| 11224594713 | Megabyte | 1,000 kilobytes or 1,000,000 bytes | 4 | |
| 11224598898 | Gigabyte | a unit of information equal to one billion (109) or, strictly, 230 bytes. | 5 | |
| 11224594714 | Terabyte | a unit of information equal to one million million (1012) or strictly, 240 bytes. | 6 | |
| 11224608826 | Bitrate | the number of bits that are conveyed or processed per unit of time | 7 | |
| 11224608827 | Bandwidth | Transmission capacity measure by bit rate | 8 | |
| 11224625344 | Algorithm | a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. | 9 | |
| 11224629708 | Metadata | is data that describes other data. For example, a digital image my include metadata that describe the size of the image, number of colors, or resolution. | 10 | |
| 11224629709 | Encoding | 11 | ||
| 11224652706 | Byte | Made of 8 bits | 12 | |
| 11224652707 | Bit | a small piece, part, or quantity of something. | 13 | |
| 11224661744 | Data Compression | 14 | ||
| 11224845561 | Text Compression | Data compression is a reduction in the number of bits needed to represent data. Compressing data can save storage capacity, speed up file transfer, and decrease costs for storage hardware and network bandwidth. | 15 | |
| 11224933362 | Compression Dictionary | a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure (called the 'dictionary') maintained by the encoder. | 16 | |
| 11224933363 | Compression Rate | In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. | 17 | |
| 11225021305 | Decimal | Relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten. | 18 | |
| 11225021306 | Binary | A coding language that only uses 0 and 1 to represent all other characters and quantities | 19 | |
| 11225021307 | Hexadecimal | A coding language that goes from 0 to 9, then A to F. Each character is represented by 4 bits of binary. | 20 | |
| 11225026207 | Number System | A collection of various symbols which are called digits. | 21 | |
| 11225115648 | Pixel | 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. | 22 | |
| 11225115649 | B&W Pixel | Black and White picture element. Represented by 1 bit (on/off) which translates to black/white | 23 | |
| 11225119918 | Color Pixel | Short for Picture Element, a pixel is a single point in a graphic image. | 24 | |
| 11225257464 | RGB | RGB (red, green, and blue) refers to a system for representing the colors to be used on a computer display. Red, green, and blue can be combined in various proportions to obtain any color in the visible spectrum. | 25 | |
| 11225867529 | CODEC | a device or program that compresses data to enable faster transmission and decompresses received data. | 26 | |
| 11225867530 | Container | type of file format that contains various types of data compressed by standardized codecs. | 27 | |
| 11237274782 | ASCII | American Standard for Information Interchange - a system for character encoding. It uses 8 bits for a byte. | 28 |
