CMYK

CMYK stands for cyan magenta yellow and blacK and is a color system used in the offset printing of full-color documents.

Offset uses cyan, magenta, yellow, and black inks and is often referred to as “four-color” printing. Monitors use red, green, and blue light instead, so they display images using a different color system called RGB. One of the great problems of the digital age has been matching colors between these two systems; i.e., taking a digital RGB image and making it look the same in print using CMYK. These problems are addressed by applications such as the Pantone Matching System.

Hits

If anyone who isn’t a network engineer mentions “hits” to you, they’re probably trying to pull the cyberwool over your eyes. Hits are the individual requests a server answers in order to render a single web page completely. The page document itself, the various images on the page, any other media files embedded there – each of these items represents a separate hit. In other words, the more GIFs used in a page, the higher the hit count – so while hits may be a good indication of poor page design, they won’t tell you much about traffic.

Multimedia

Multimedia describes the ability of a computer to present and combine text, graphics, video, animation, and sound.

Before the personal computer boom, the word multimedia had a much simpler connotation – paper, glass, and acrylic on canvas was (and is) multimedia. The birth of the web led to a great potential for multimedia, because of the ability of networked computers to deliver this information to all users and to allow everyone to join in the world of multimedia publishing.

Raster


Raster graphics are bitmap images, which means they’re basically grids of individually defined pixels (as opposed to vector graphics, which produce images using mathematically generated points and lines). The dominant web graphics formats, GIF and JPEG, are raster graphics. Raster is often used with complex images, such as photographs.

Unix


Unix, along with Linux and Windows, is one of the most widely-used and oldest operating systems in the world. Since it operates on every hardware platform imaginable, Unix is used to running just about any type of software application you can think of. Banking applications, web servers, videogames and research stations are just a few possible uses for this diverse OS. Since Unix code was originally distributed freely among universities, government institutions and research laboratories, Unix is considered to be the first open-source operating system. Some open-source permutations of Unix are FreeBSD, OpenBSD, Darwin, and Linux. Some commercial distributions of Unix are SCO, Solaris, and AIX.
