Terminal (OS X)

Terminal (Terminal.app) is the terminal emulator included in the OS X operating system by Apple. Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of OS X.

As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of OS X, by providing a command line interface to the operating system when used in conjunction with a Unix shell, such as bash.

The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. These settings do not alter the operation of Terminal, and the xterm settings do not match the behavior of xterm.

Terminal includes several features that specifically access OS X APIs and features. These include the ability to use the standard OS X Help search function to find manual pages and integration with Spotlight. Terminal was used by Apple as a showcase for OS X graphics APIs in early advertising of Mac OS X, offering a range of custom font and coloring options, including transparent backgrounds.

Mac OS X Snow Leopard

Mac OS X Snow Leopard (version 10.6) is the seventh major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers.

Snow Leopard was publicly unveiled on June 8, 2009 at the Apple Worldwide Developers Conference. On August 28, 2009, it was released worldwide, and was made available for purchase from Apple's website and its retail stores at the price of US$29 for a single-user license. As a result of the low price, initial sales of Snow Leopard were significantly higher than that of its predecessors. The release of Snow Leopard came nearly two years after the introduction of Mac OS X Leopard, the second longest time span between successive Mac OS X releases (the time span between Tiger and Leopard was the longest).

Unlike those of previous versions of Mac OS X, the goals of Snow Leopard were improved performance, greater efficiency and the reduction of its overall memory footprint. Addition of new end-user features was not a primary consideration: its name signified its goal to be a refinement of the previous OS X version, Leopard. Much of the software in Mac OS X was extensively rewritten for this release in order to take advantage fully of modern Macintosh hardware. New programming frameworks, such as OpenCL, were created, allowing software developers to use graphics cards in their applications. This is also the first Mac OS release since System 7.1.1 that does not support Macs using PowerPC processors, as Apple now intends to focus on its current line of Intel-based products. As support for Rosetta was dropped in OS X Lion, Snow Leopard is the last version of Mac OS X that is able to run PowerPC-only applications.

OS X El Capitan

OS X El Capitan (el-KAP-ɪ-TAN) (version 10.11) is the twelfth major release of OS X, Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security. Following the California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park.

The first beta of OS X El Capitan was released to developers shortly following the 2015 WWDC keynote on June 8, 2015. The first public beta was made available on July 9, 2015. There were multiple betas released after the keynote. OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.

System requirements

All Macintosh computers that can run OS X Mavericks or Yosemite can run El Capitan, although not all of its features will work on older computers. For example, Apple notes that newly available Metal API is available on "all Macs since 2012".

OS X Mavericks

OS X Mavericks (version 10.9) is the tenth major release of OS X, Apple Inc.'s desktop and server operating system for Macintosh computers. OS X Mavericks was announced on June 10, 2013, at WWDC 2013, and was released on October 22, 2013, as a free upgrade through the Mac App Store worldwide.

The update emphasized battery life, Finder improvements, other improvements for power users, and continued iCloud integration, as well as bringing more of Apple's iOS apps to OS X. Mavericks, which was named for the surfing location in California, was the first in the series of OS X releases named for places in Apple's home state; earlier releases used the names of big cats.

History

Apple announced OS X Mavericks on June 10, 2013, during the company's Apple Worldwide Developers Conference (WWDC) keynote (which also introduced iOS 7, a revised MacBook Air, the sixth-generation AirPort Extreme, the fifth-generation AirPort Time Capsule, and a redesigned Mac Pro). During a keynote on October 22, 2013, Apple announced that the official release of 10.9 on the Mac App Store would be available immediately, and that unlike previous versions of OS X, 10.9 would be available at no charge to all users running Snow Leopard (10.6.8) or later.

Electronics, telecommunication, and computers

Terminal (electronics)

A terminal is the point at which a conductor from an electrical component, device or network comes to an end and provides a point of connection to external circuits. A terminal may simply be the end of a wire or it may be fitted with a connector or fastener. In network analysis, terminal means a point at which connections can be made to a network in theory and does not necessarily refer to any real physical object. In this context, especially in older documents, it is sometimes called a pole.

The connection may be temporary, as seen in portable equipment, may require a tool for assembly and removal, or may be a permanent electrical joint between two wires or devices.

All electric cells have two terminals. The first is the positive terminal and the second is the negative terminal. The positive terminal looks like a metal cap and the negative terminal looks like a metal disc. The current flows from the positive terminal, and out through the negative terminal, replicative of current flow (positive (+) to negative (-) flow).

Terminal (band)

Terminal was an American rock band from Mansfield, Texas.

History

Formation and How the Lonely Keep

Formed in 1998 under the name Letter Twelve, the group signed to Tooth & Nail Records in 2004 and changed its name. The band's first, and only, release under this name was entitled How the Lonely Keep, and in 2005 they went on tour with labelmates Anberlin. The record hit number 39 on the Billboard Top Christian Albums chart in 2005. Matthew Tsai of Absolute Punk called the record "one of the great emo releases of the 00's". Melodic.net compared the group to Anberlin, Jimmy Eat World, and Third Eye Blind.

Shortly after the release of the album, all of the band's members except for lead singer Travis Bryant departed the group during their tour with The Spill Canvas and Rufio; Bryant toured with Terminal as a solo act for the remainder of the tour. Bryant found replacements for the members later in 2005 and continued to tour behind the album, touring with Saosin, He Is Legend, The Juliana Theory, Cartel, The Working Title, Codeseven, The Receiving End of Sirens, and Yesterdays Rising. Terminal split in January 2006.
