JFS Definition Stands for “Journaled File System.” JFS is a 64-bit file system created by IBM. The initial version of JFS (also called JFS1) was developed for IBM’s AIX operating system and was released in 1990. In 2001, IBM released JFS2 (the Enhanced Journaled File System), as well as a version of JFS that is compatible with the Linux operating system. ..

Monochrome Definition The word “monochrome” literally means “one color.” Therefore, a monochrome image only includes one color, but may contain many shades. In computing, “monochrome” typically refers to a two-tone image, rather than one with several shades of a single color.

Halftone Definition A halftone, or halftone image, is an image comprised of discrete dots rather than continuous tones. When viewed from a distance, the dots blur together, creating the illusion of continuous lines and shapes. By halftoning an image (converting it from a bitmap to a halftone), it can be printed using less ink. Therefore, many newspapers ..

CMYK Definition Stands for “Cyan Magenta Yellow Black.” These are the four basic colors used for printing color images. Unlike RGB (red, green, blue), which is used for creating images on your computer screen, CMYK colors are “subtractive.” This means the colors get darker as you blend them together. Since RGB colors are used for light, not ..

Hertz Definition Hertz (abbreviated: Hz) is the standard unit of measurement used for measuring frequency. Since frequency is measured in cycles per second, one hertz equals one cycle per second. Hertz is used commonly used to measure wave frequencies, such as sound waves, light waves, and radio waves. For example, the average human ear can detect ..

Kilohertz Definition One kilohertz (abbreviated “kHz”) is equal to 1,000 hertz. Like hertz, kilohertz is used to measure frequency, or cycles per second. Since one hertz is one cycle per second, one kilohertz is equal to 1,000 cycles per second. Kilohertz is commonly used to measure the frequencies of sound waves, since the audible spectrum of sound ..

RGB Definition Stands for “Red Green Blue.” RGB refers to three hues of light that can be mixed together to create different colors. Combining red, green, and blue light is the standard method of producing color images on screens, such as TVs, computer monitors, and smartphone screens. The RGB color model is an “additive” model. When 100% of ..
