A process that runs in the background and performs a specified operation at predefined times or in response to certain events. The term daemon is a UNIX term, though many other operating systems provide support for daemons, though they’re sometimes called other names. Windows, for example, refers to daemons as System Agents and services.
Typical daemon processes include print spoolers, e-mail handlers, and other programs that perform administrative tasks for the operating system. The term comes from Greek mythology, where daemons were guardian spirits.
Pronounced DEE-mun or DAY-mun.
Often simply called a ‘driver’, this is a piece of programming code that enables a host device, such as a PC, to operate an attached device such as a mouse, graphics card or webcam. A large number of device drivers come pre-packaged with Windows and other operating systems, enabling the devices to work without any extra software. However, the latest features and bug fixes will be found in the most recent versions of the drivers, which can usually be downloaded from manufacturers’ websites.
Devil’s Canyon is Intel’s codename for the unlocked ‘K’ editions of the “refresh” revision of the Core i5 and Core i7 Haswell processors. These include the Core i5-4690K and Core i7-4790K which feature improved thermal interface material, thereby allowing cooler operation and improved overclocking.
Digital distribution (also called content delivery, online distribution, or electronic software distribution (ESD), among others) is the delivery or distribution of media content such as audio, video, software and video games. The term is generally used to describe distribution over an online delivery medium, such as the Internet, thus bypassing physical distribution methods, such as paper, compact discs, and DVDs. The term online distribution is typically applied to freestanding products; downloadable add-ons for other products are more commonly known as downloadable content. With the advancement of network bandwidth capabilities, online distribution became prominent in the 2000s.
Content distributed online may be streamed or downloaded, and often consists of books, films and television programs, music, software, and video games. Streaming involves downloading and using content at a user’s request, or “on-demand”, rather than allowing a user to store it permanently. By contrast, fully downloading content to a hard drive or other form of storage media may allow offline access in the future.
Specialist networks known as content delivery networks help distribute content over the Internet by ensuring both high availability and high performance. Alternative technologies for content delivery include peer-to-peer file sharing technologies. Alternatively, content delivery platforms create and syndicate content remotely, acting like hosted content management systems.
