supports: A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive. The user interface (UI), in the industrial design field of humancomputer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology. The Amiga is a family of personal computers sold by Commodore in the 1980s and 1990s. Based on the Motorola 68000 family of microprocessors, the machine has a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS. The Amiga provided a significant upgrade from earlier 8-bit home computers, including Commodore's own C64. DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions. MPEG-1 and/or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players and computing devices. Ripping is extracting all or parts of digital contents from a container. Originally it meant to rip music out of Amiga games. Later the term was used to extract WAV or MP3 format files from digital audio CDs, but got applied as well to extract the contents of any media, most notable were DVD and blue-ray disks. Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time. The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves. The graphical user interface (GUI ), is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other 
  resource. The act of "accessing" may mean consuming, entering, or using. Permission to access a resource is called "authorization". Waveform Audio File Format (WAVE, or more commonly known as WAV due to its filename extension) (rarely, Audio for Windows) is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. It is an application of the Resource Interchange File Format (RIFF) bitstream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. It is the main format used on Windows systems for raw and typically uncompressed audio. The usual bitstream encoding is the linear pulse-code modulation (LPCM) format. A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. A peripheral is "an ancillary device used to put information into and get information out of the computer". Digital rights management (DRM) schemes are various access control technologies that are used to restrict usage of proprietary hardware and copyrighted works. DRM technologies try to control the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems within devices that enforce these policies. Opendisc is an Enhanced Music CD application for enabling multimedia content when a compact disc is played on a personal computer . Opendisc asserts that its technology conforms to the Blue Book specification and does not contain copy - protection functions . However , various computer users have reported that it interferes with third - party playback and ripping applications , effectively functioning as Digital Rights Management . Since version 2.0 , Opendisc embedded a direct link to a default audio player such as Windows Media Player or iTunes . Because of this , many CDs now simply feature access to a Web site of the specific artist , which features exclusive music , videos , and photo content . Like a Google alert , a user is informed of artist updates via e-mail .
