ipod

iPod is a line of portable media players designed and marketed by Apple and launched on October 23, 2001. The product line-up currently consists of the hard drive-based iPod Classic, the touchscreen iPod Touch, the compact iPod Nano, and the ultra-compact iPod Shuffle. iPod Classic models store media on an internal hard drive, while all other models use flash memory to enable their smaller size (the discontinued Mini used a Microdrive miniature hard drive). As with many other digital music players, iPods can also serve as external data storage devices. Storage capacity varies by model, ranging from 2 GB for the iPod Shuffle to 160 GB for the iPod Classic. All of the models have been redesigned multiple times since their introduction. The most recent iPod redesigns were introduced on September 1, 2010.

Apple's iTunes software can be used to transfer music to the devices from computers using certain versions of AppleMacintosh and Microsoft Windows operating systems. For users who choose not to use iTunes or whose computers cannot run iTunes, several open source alternatives are available for the iPod. iTunes and its alternatives may also transfer photos, videos, games, contact information, e-mail settings, Web bookmarks, and calendars to iPod models supporting those features.

The iPod branding is also used for the media player applications included with the iPhone and iPad; the iPhone version is essentially a combination of the Music and Videos apps on the iPod Touch. Both devices can therefore function as iPods, but they are generally treated as separate products.

Discontinued models of the line include the iPod Mini and the iPod Photo, the former being replaced by the iPod Nano, and the latter reintegrated into the main line as the iPod Classic.

wikipedia

A wiki  is a website that allows the creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. Wikis are typically powered by wiki software and are often used collaboratively by multiple users. Examples include community websites, corporate intranets, knowledge management systems, and note services. The software can also be used for personal notetaking.

Wikis serve different purposes. Some permit control over different functions (levels of access). For example editing rights may permit changing, adding or removing material. Others may permit access without enforcing access control. Other rules can be imposed for organizing content.

Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described it as "the simplest online database that could possibly work.
