The graphical ___MASK73___ ___MASK69___ ( GUI ), is a type of ___MASK73___ ___MASK69___ that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation , instead of text - based ___MASK73___ interfaces , typed ___MASK79___ labels or text navigation . GUIs were introduced in reaction to the perceived steep learning curve of ___MASK79___ - line interfaces ( CLIs ), which require commands to be typed on a computer keyboard . MPEG - ___MASK64___ 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 . Opendisc is an Enhanced ___MASK28___ CD ___MASK30___ 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 . ___MASK19___ ( 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 ___MASK66___ and other computer files as well as video programs watched using ___MASK19___ players . DVDs offer higher storage capacity than compact discs while having the same dimensions . A ___MASK44___ 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 ___MASK75___ of industrial and consumer devices . This includes simple special purpose devices like microwave ovens and remote controls , factory devices such as industrial robots and ___MASK44___ assisted ___MASK81___ , but also in general purpose devices like personal computers and mobile devices such as smartphones . The ___MASK93___ is run on computers and it connects millions of other computers . The ___MASK73___ ___MASK69___ ( UI ), in the industrial design field of human  computer interaction , is the space where interactions between humans and machines occur . The ___MASK4___ 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 ___MASK73___ interfaces include the interactive aspects of computer operating systems , hand tools , heavy machinery operator controls , and process controls . The design considerations applicable when creating ___MASK73___ interfaces are related to or involve such disciplines as ergonomics and psychology . Ripping is extracting all or parts of digital contents from a ___MASK60___ . Originally it meant to rip music out of ___MASK86___ games . Later the term was used to ___MASK62___ WAV or MP3 format files from digital audio CDs , but got applied as well to ___MASK62___ the contents of any media , most notable were ___MASK19___ and blue - ray disks . In the fields of physical ___MASK36___ and information ___MASK36___ , 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 ". A ___MASK83___ ( 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 ___MASK69___ such as Windows . The versatility of a ___MASK83___ is greatly enhanced by the use of peripheral devices such as a keyboard , monitor , ___MASK20___ , mouse , speakers , and an external hard drive . ___MASK51___ ( 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 ___MASK66___ and multimedia content ), as well as systems within devices that enforce these policies . The ___MASK86___ is a ___MASK13___ of personal computers sold by Commodore in the 1980s and 1990s . Based on the Motorola 68000 ___MASK13___ of microprocessors , the machine has a custom chipset with graphics and ___MASK42___ capabilities that were unprecedented for the price , and a pre - emptive multitasking ___MASK40___ called AmigaOS . The ___MASK86___ provided a significant upgrade from earlier 8 - bit home computers , including Commodore ' s own C64 . Copyright is a legal right created by the ___MASK85___ of a country that grants the creator of an original work exclusive ___MASK58___ for its use and distribution . This is usually only for a limited ___MASK90___ . The exclusive ___MASK58___ are not absolute but limited by limitations and exceptions to copyright ___MASK85___ , including fair use . A major limitation on copyright is that copyright protects only the original expression of ideas , and not the underlying ideas themselves . Waveform Audio ___MASK71___ ( WAVE , or more commonly known as WAV due to its filename extension ) ( rarely , Audio for Windows ) is a Microsoft and IBM audio ___MASK71___ standard for storing an audio bitstream on PCs . It is an ___MASK30___ of the Resource Interchange ___MASK71___ ( 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 peripheral is " an ancillary ___MASK61___ used to put ___MASK32___ into and get ___MASK32___ out of the computer ".
