Chime (bell instrument)
A carillon-like instrument with fewer than 23 bells is called a chime.
American chimes usually have one to one and a half diatonic octaves. Many chimes are automated.
The first bell chime was created in 1487. Before 1900, chime bells typically lacked dynamic variation and the inner tuning (the mathematical balance of a bell's complex sound) required to permit the use of harmony. Since then, chime bells produced in Belgium, the Netherlands, England, and America have inner tuning and can produce fully harmonized music. Some towers in England hung for full circle change ringing chime by an Ellacombe apparatus.
Notable chimes
Macintosh startup
The Macintosh startup sequence behaviors include the startup chime, Happy Mac, Sad Mac and Chimes of Death.
Startup chime
The Macintosh startup chime is the single note or chord (depending on model type) played when an Apple Macintosh computer is turned on. The sound indicates that diagnostic tests run immediately at startup have found no hardware or fundamental software problems.
Mark Lentczner created the code for the arpeggiated chord used on the Macintosh II. Variations of this sound were used until Jim Reekes created the startup chime used for the Quadra 700 through the Quadra 800. Reekes said, "The startup sound was done in my home studio on a Korg Wavestation. It's a C major chord, played with both hands stretched out as wide as possible (with 3rd at the top, if I recall)." He was also the creator of the iconic (or "earconic", as he calls it) "bong" startup chime used in most Macintoshes since the Quadra 840AV. A slightly lower-pitched version of this chime was used on all PCI-based Power Macs until the iMac G3. The Macintosh LC, LC II, and Macintosh Classic II do not use the Reekes chime, instead using an F major chord that just produces a "ding" sound. The first generation of Power Macintosh computers also do not use the Reekes chime, instead using a chord strummed on a Yamaha 12-string acoustic guitar by jazz guitarist Stanley Jordan. Further, the Power Macintosh 5200–6300 computers (excluding the 5400 and 5500, which still had the "bong" chime) used an exclusive chime not used on any other Macintosh model, and the 20th Anniversary Macintosh also used a special startup chime as well, exclusive to this particular Macintosh.
JPEG
JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.
The term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.
